Let's Visit Alentejo, Portugal through the Herdade do Esporão Reserva

Herdade do Esporão is a Portuguese wine brand that many readers might have familiarity with.  They are the largest producer in the Alentejo region and also the most widely distributed in the U.S.. We love receiving samples from this producer.

As a refresher, Alentejo covers much of Portugal’s southern half, spanning the flatlands below the Tejo River down to Portugal's southern Atlantic Coast. It accounts for 13% of Portugal's area under vine and 18% of wine production. Alentejo incorporates eight sub-viticultural zones (from north to south: Portalegre, Borba, Évora, Redondo, Reguengos, Granja-Amareleja, Vidigueira, & Moura).  The climate is hot and dry with both a Continental and Mediterranean climate with winters exceptionally cold whereas spring and summer are dry and hot. The region experiences high levels of sunshine in the growing season -- over 3,000 hours annually. Wine-searcher.com also shares that the "Alentejo is broadly flat with hilly areas dotted across its zone. Major mountainous or hilly regions across the area include the Serra de São Mamede (1025m) on the border with Spain at the very northeastern end of the area, and the Serra de Portel (421m) and the Serra d’Ossa (649m), both in the central east".

The Herdade do Esporão estate is located in the Reguengos de Monsaraz DOC sub-region which itself is located squarely in central Alentejo. The granite and schist soils and the local climate are particularly favorable to vine-growing and the region is well known for its production of high-quality wines with their own distinctive characteristics (VisitPortugal).  The region provides the estate with two key advantages: access to water and diversity of soils. According to the winery, "Alentejo is a dry region, averaging just 58 cm/23 inches of rainfall per year. The estate sits on a probable north–south fault zone; fault zones coincide with areas blessed with groundwater. This relative abundance of water was decisive to the medieval occupation of the land and building of the defensive Esporão tower.

Soil mapping begun in 2008 by geologist José Borrego established that at least seven different soils exist within the property, with dioritic soils (medium- to coarse-grained igneous rock) found only at the estate. Dioritic soils result in wines wines with lots of aroma, fruit, and acidity. Granite-origin granodiorite soils eventually yield wines with great freshness and minerality. Other soils include mottled schists (the Reserva Red) for grapes with high sugar and phenol levels, and two different versions of sandy clay loam soils are home to some of the white grapes".

The boundaries of the Herdade do Esporão estate were first established in 1267 and have been unaltered since.  In 1973, José Roquette and Joaquim Bandeira bought the property because the Reguengos sub-region "ensures wines that were full-bodied but elegant and both big and seductive, thanks to a mix of very poor, stony soils and a harsh climate".  The first wine was produced in 1985 using the brand name Esporão which coincidently was the Esporão Reserva Red -- which we will be reviewing the 26th vintage. Currently, they have 450 hectares of vines planted with 194 grape varieties, 37 of which are in full production. Three of these grapes are included in the Reserva White and five in the Reserva Red.

Esporão Reserva White 2022 ($23)
The grapes for this blend of Antão Vaz, Arinto, Roupeiro were grown on a granite/schist base with a loam/clay structure. After harvest, 75% of the grapes were fermented in stainless steel tanks and the remaining 25% in new American and French oak barrels. This slight oak treatment yields a creamy and structured core surrounded by a white floral and slightly citrus aroma and a fresh herbaceous finish. 

Esporão Reserva Red 2021 ($23)
Red blends comprise a large percentage of Alentejo output and this wine is a blend of Alicante Bouschet, Touriga Nacional, Aragonez, Trincadeira, and Cabernet Sauvignon. Each variety was vinified separately, destemmed, crushed, temperature controlled alcoholic fermentation in stainless steel vats, concrete tanks and small marble lagares, pressed, followed by malolactic fermentation in stainless steel tanks. The wine then spent 12 months in new (20%) and old (80%) American and French oak barrels. After bottling, the wine aged  at least 6 months in the bottle. This is one of my favorite Portuguese wines with dark fruit (blackberries, plums, and dark cherries), spice and herbs, and a wonderful structured balance with the approachable tannins and pop rocks acidity. 

Notes on the Grapes:

Antão Vaz: This is the most dominate white grape in Alentejo and most prevalent in the Vidigueira and Reguengos sub-regions. The berries are loosely clustered and thick skinned providing disease resistance and they are also able to cope with drought-like conditions. In general it can provide stone and tropical fruit notes, various nuts, minerality, and ripe citrus. 

Arinto: Alentejo's best white blending variety, thanks to its exuberant acidity. Discreet aroma. Green apple, lemon, and lime freshness and mineral notes. Arinto has large leaves for shading and super-high acidity, making it well suited to the hot Alentejo climate.

Roupeiro:  A pale-skinned grape variety that is grown throughout Portugal under several aliases. Wines with Roupeiro exhibit citrus and stone fruit flavors with noticeable aromatic lift.

Alicante Bouschet: Although not indigenous to Portugal it has found a home accounting for 2% of all Portuguese plantings and ranking #8 for all reds. The grape thrives in Alentejo, particularly in Vidigueira and Reguengos, and is the second most planted red grape after Aragonez. It produced dense wines with dark fruit, pepper, smoke, and abundant tartness and astringency. 

Touriga Nacional: A dark-skinned grape variety that is widely believed to produce the finest red wines of Portugal. Called Portugal's answer to France's Cabernet Sauvignon. 

Aragonez: This is a southern Portuguese name for Tempranillo known to produce red wines with red fruit and leather aromas, high tannins, moderate to low acidity, and moderate alcohol. 

Trincadeira: Considered one of the oldest varieties of Portugal. The wines produced from this grape grape are full-bodied and very rich as to their flavor. The aromas are fresh and herbaceous with flavors of blackberries and flowers.

The 'A's of Alentejo Wine Masterclass

Alentejo is Portugal's largest viticultural zone and covers much of Portugal’s southern half, spanning the flatlands below the Tejo River down to Portugal's southern Atlantic Coast. It accounts for 13% of Portugal's area under vine and 18% of wine production. Alentejo incorporates eight sub-viticultural zones (from north to south: Portalegre, Borba, Évora, Redondo, Reguengos, Granja-Amareleja, Vidigueira, & Moura). 

The climate is hot and dry with both a Continental and Mediterranean climate with winters exceptionally cold whereas spring and summer are dry and hot. The region experiences high levels of sunshine in the growing season -- over 3,000 hours annually. Wine-searcher.com also shares that the "Alentejo is broadly flat with hilly areas dotted across its zone. Major mountainous or hilly regions across the area include the Serra de São Mamede (1025m) on the border with Spain at the very northeastern end of the area, and the Serra de Portel (421m) and the Serra d’Ossa (649m), both in the central east".

Portugal has one of the most expansive number of native grape varieties at close to 250, which is the highest density of native grapes per square mile of any country in the world. These grapes are also reflected in Alentejo with the native Antão Vaz, Arinto, and Alfrocheiro joining the international varieties Aragonez (Tempranillo) and Alicante Bouschet as major players. 

These Alentejo wine facts were stressed during a recent Masterclass presented by Master Sommelier Evan Goldstein titled The 'A's of Alentejo. During the presentation we sipped six wines, each representing an "A" fact about the region. The wines were part of a Master the World wine kit of small bottles.

Antão Vaz - The Grape
This is the most dominate white grape in Alentejo and most prevalent in the Vidigueira and Reguengos sub-regions. The berries are loosely clustered and thick skinned providing disease resistance and they are also able to cope with drought-like conditions. In general it can provide stone and tropical fruit notes, various nuts, minerality, and ripe citrus. These characteristics were prevalent in the Herdade de Malhadinha Nova Antão Vaz da Malhadinha Branco 2022 ($30) with tropical, tangly lemons, cashews, and racing minerality. 

Altitude
Although Alentejo is predominately flat, there are areas of significant height that provides important micro-climate benefits. In the northern region of Portalegre, vines planted on on steep slopes at close to 2,500 feet in the Serra de São Mamede benefit from lower temperatures and higher levels of humidity, yielding fresh, elegant wines.  This was evident in the Quinta da Fonte Souto Branco 2021 ($29), a blend of 75% Arinto and 25% Verdelho and aged in various oak treatments. The grapes were harvested from two vineyards located at 1,640 feet. The wine is excellent with a creamy, generous mouthfeel; stone fruits; and a lasting somewhat chewy and tannic finish.  

Amphora/Talha
The Phoenicians introduced viticulture into Portugal 2,500 years ago as well as the use of clay pots in the winemaking process. These talhas de barro or amphorae hold up to 520 gallons of wine and can be as large as seven-feet in height, and weigh a ton. The clay pots are lined with Pez - a mix of pine resin and beeswax to make the clay impenetrable. Unlike the Georgian process, amphora in Alentejo are stored above ground and are moistened during the fermentation process to lower temperatures.  During this segment we sampled the Jose Maria da Fonseca Jose de Sousa 2017 ($19), a blend of Grand Noir, Touriga Francesa, and Touriga Nacional.  It is dry, jammy with cherry and plums and a jolting tannic structure that mellows as the wine settles in the glass. 

Alentejano Blends
Red blends comprise a large percentage of Alentejo output and the Fitapreta Tinto 2021 ($27) was appointed as their representative. This wine was fermented using native yeasts an is a blend of four grape varieties featuring primarily Aragonez (Tempranillo) and Alicante Bouschet. Expect a dry wine with loads of dark plum flavors interspersed with earthy tones and a chewy-tannic finish. 

Activism
In 2015, the Wines of Alentejo Sustainability Program (WASP) was created to identify and certify sustainable farming and winemaking practices. Today the certification includes 171 criteria which 651 members have met. These criteria include reducing pesticides and other chemicals, conserving water,  soil management, and worker wellbeing. Casa Agricole Alexandre Relvas is WASP certified and dedicates a portion of its land to preserve local endangered plant species.  We sipped a wine from their first label, the Herdade de São Miguel Colheita Seleccionada Tinto 2018 ($16). This another four grape red blend dominated by Alicante Bouschet and Touriga Nacional and is fresh and vibrant with a bright cherry nose, fresh fruit, and a long acidic finish. 

Alicante Bouschet
Although not indigenous to Portugal it has found a home accounting for 2% of all Portuguese plantings and ranking #8 for all reds. The grape thrives in Alentejo, particularly in Vidigueira and Reguengos, and is the second most planted red grape after Aragonez. It produced dense wines with dark fruit, pepper, smoke, and abundant tartness and astringency.  The Herdade de Rocim Alicante Bouschet 2021 ($23) is drinkable now but will benefit with more age as the licorice and tart, astringent, and tannic characters mellow into juicy dark fruit. 

Grape Spotlight: Alentejo's Portalegre DOC and Arinto

Located along the Spanish border, the Portalegre DOC is Alentejo's northernmost subregion and is completely different from the rest of the Alentejo -- from the altitude to the soils, from the vineyard sizes to the age of the vines. The vineyards are located at the foothills of the Serra de São Mamede mountain range, between 600 and 700 meters above sea level. Thus the climate is cooler and wetter than the baking plains of southern Alentejo. And it receives influences from both the Atlantic and Mediterranean. The soils are primarily granite and interspersed with small patches of schist in the lower areas. Vineyards tend to be fragmented in the hills, divided into numerous small plots of very old vines -- many of which may be seventy years old.  In general, these conditions help produce fresh and elegant wines, yet equally powerful.

Arinto is a late-ripening, medium-sized yellowish grape that's naturally high acid content makes it well suited for the hot Alentejo environment. And the tightly packed bunches are shaded from the hot sun by the vine's large leaves. The grape provides a range of profiles from grapefruit to lemon and lime and green apple to some stone fruits. 

The Adegas de Portalegre Winery was founded in 1954 by a small group of winegrowers and is actually located in a Natural Park -- the Natural Park of Serra de São Mamede. This means the vines are planted at high altitudes, between 600 and 700 meters, and the average age of these vineyards are 70 years old. We received a sample of their Conventual Reserva Vinho Bianco 2018 which is a unique blend of Arinto, Fernão Pires, Syrah, and Bical. The Syrah grapes were harvested from the Serra da Penha vineyard -- an eight-hectare granite soil plot that starts at 450m and runs to the top of Serra da Penha at 650 meters. The other grapes were grown in the Quinta da Cabaça vineyard, an even higher plot with clay and granite soils. The wine is very complex starting with a white flower aroma, then moving towards a saline and white peach profile, and ending with excellent acidity. The 14% alcohol is unnoticeable. 

The Herdade da Torre de Palma is located in Monforte, Portalegre, and farms seven hectares in their estate vineyard, which interestingly enough, is planted with seven different grape varieties. The vineyard consists of light clay soil on top of the granite with smaller instances of limestone, schist, sandstone, and marble. The vineyard receives wide diurnal temperature swings which extend the maturation period - leading to increased acidity. The wines are created by enologist Duarte de Deus who tends towards a minimalist approach. That being said, the Torre de Palma Arinto - Alvarinho 2021 was fermented and aged on its lees in French oak. There is definitely a sense of depth in this wine with a strong citrus profile, complemented by a touch of tropical notes and minerality. 

White Wines from Portugal's Alentejo Wine Region

I'm rather excited about receiving these six white wines from Portugal's Alentejo wine region -- a region of rolling plains that covers more than 30% of Portugal and is the largest in the country. Alentejo is located a 90-minute car ride to the east of Lisbon and is a hot and dry Mediterranean climate influenced more by the continent than by the Atlantic Ocean or the Mediterranean Sea. Since Portugal has the highest density of native grapes per square mile of any country in the world, it's no surprise that there are plenty of autochthonous grapes in Alentejo like Antão Vaz, Arinto, Viosinho, and Fernão Pires. The region is also home to many international white grape varieties such as Roupeiro (Malvasia), Verdelho, Vermentino, and Viognier. 

The Alentejo DOC consists of eight sub-regions: Borba, Évora, Granja-Amareleja, Moura, Portalegre, Redondo, Reguengos and Vidigueira. In general, these sub-regions share a common soil structure alternating between schist, clay, marble, granite and limestone. Borba, Évora, Redondo and Reguengos are the core of Alenejo's identity where the wines display a balance between freshness and fruit, intensity and softness. The sub-regions of Granja-Amareleja, Moura and Vidigueira are located in the southern areas of the appellation where the climate is harsher and soils more nutrient-poor. Wines from this region are softer with more minerality.  Portalegre is the most unique sub-region, with predominantly granite soils, and influenced by the Serra de São Mamede. Vines are planted on the steep slopes of the mountain and benefit from a microclimate that delivers both freshness and complexity.

Culturally, Alentejo has experienced the influences of numerous civilizations from the Phoenicians, Greeks, Celts, Romans, and Moors. The Phoenicians introduced the knowledge of writing (the Iberian script is based on the Phoenician’s), the potter’s wheel, and contributed to expanding the arts of agriculture, navigation and iron metallurgy in the Iberian Peninsula (Phoenicians and Greeks in the Iberian Peninsula).  The Celts perhaps introduced brewing to the region with archaeological evidence showing beer production over 2.5 - 3 thousand years ago. The basis for the Latin cremor,  Portuguese cerveja, and Spanish cerveza is thought to be the Proto-Celtic word kormi.  The Romans had the largest impact on viticulture and wine made in Alentejo was perhaps the first export of Portuguese wines to Rome.  The marks of Roman civilization are still noticeable over two thousand years later with the continued use of trimmer or clay jars for the fermentation of musts and the storage of wine. And the conquest by the Moors did not completely eliminate these practices and the remnants of that civilization can be seen in the numerous castles, Muslim mosques, and walls built to protect the cities. 

I started my tasting with two Colheita wines, each from the Reguengos and Évora sub-regions. According to their website, Herdade do Esporão, the boundaries of the estate were first established in 1267 and have been unaltered since then. They have 450 hectares of vines planted with 194 grape varieties, 37 of which are in full production. In 1973, José Roquette and Joaquim Bandeira bought the property because the Reguengos sub-region "ensures wines that were full-bodied but elegant and both big and seductive, thanks to a mix of very poor, stony soils and a harsh climate".  The first wine was produced in 1985 using the brand name Esporão. The Esporão Colheita Branco 2021 ($18) is made from organically and estate-grown Antão Vaz, Viosinho, and Vermentino grapes that were partially fermented in concrete tanks. After fermentation, the wine was left on the fine lees for 4 months.  The wine is very complex with a tropical nose, lemon and stone fruitson the velvety palate, and a spicy, funky, lasting finish 

Évora shares a common topography as Reguengos' continental climate wth the soils derived from schist and clay-limestone. In 1989 João Portugal Ramos planted five hectares of vines in Estremoz after almost a decade as a consultant oenologist which had culminated in establishing his winemaking consultancy business Consulvinus. He chose Estremoz to make his own wines after working in all the main wine-growing regions of Portugal. The first wines were produced in rental facilities which established the Vila Santa brand. In 1997, the construction of the Vila Santa winery in Estremoz commenced as did the birth of the Marquês de Borba Reserva brand, with the Colheita label following the next year.  According to the winery, "the label remains the strongest brand in the group showing unwavering consistency year after year". 

The Marques de Borba Colheita White 2020 was assisted by João Maria Ramos as two of his five children have continued the family business. This wine is a blend of Arinto, Antão Vaz, and Viognier from hand-harvested grapes that were fermented in stainless steel tanks. The result is a wine showing white flowers and citrus aroma, white stone fruit, and minerality, with a structured and lasting finish. Most impressive.

Notes on the Grapes:

Antão Vaz: Versatile, perfumed and shows great solo or blended, Antão Vaz is Alentejo’s white star. This hot-climate variety is highly resistant to drought and disease, producing consistently reliable yields which ripen evenly.

Arinto: Alentejo's best white blending variety, thanks to its exuberant acidity. Discreet aroma. Green apple, lemon, and lime freshness and mineral notes. Arinto has large leaves for shading and super-high acidity, making it well suited to the hot Alentejo climate.

Viosinho:  Grown primarily in northern Portugal, it makes a full-bodied wine that adds structure and acidity to a blend along with floral and stonefruit flavors. Its wines are often described as having notes of apricots and peaches

Grape Spotlight: Alentejo's Vidigueira Antao Vaz

During the Wines of Portugal tasting that I've previously written about, I spent a considerable time at one booth, sampling several excellent wines from the Alentejo DOC. This region is named for its southerly position from the Tejo river and occupies an area directly east of Lisbon to the Spanish border.  It is sparsely populated, hot and dry, and is best known for the cork industry. Yet, it is also a highly respected wine region with a generally wave-like topography that protects much of the land from the cooling effects of the Atlantic. This contributes to the production of rich, easy-drinking red wines, as ripeness is easy to achieve in these conditions. Thus wineries in Alentejo usually focus on red wine grapes: Aragonez (Tempranillo), Castelao, Trincadeira,  Alicante Bouschet, Syrah, and Cabernet Sauvignon.

The Alentejo DOC contains eight subregions, which span from the mountains to the hot, dry center of the region: Portalegre, Borba, Évora, Redondo, Reguengos, Granja-Amareleja, Vidigueira and Moura. During the tasting, I became very impartial to the white grape Antao Vaz, which historically is autochthonous to the Vidigueira region. 

Located in the heart of the Alentejo region, the lands surrounding Vidigueira have the perfect microclimate for the perfect vineyards. Bound in the north by the Serra do Mendro mountain range, which creates a natural frontier between the Upper Alentejo and the Lower Alentejo regions, the average annual rainfall here is higher and temperatures more moderate, despite its southerly location. The schist soil too offers perfect conditions and adds mineral notes to the wine. 

The Antao Vaz grape thrives in Vidigueira's hot and dry climate yet maintains a surprisingly high level of acidity. The berries are loosely clustered and thick-skinned, giving them good disease resistance, and even in drought-like conditions remain productive and evenly ripened. Antao Vaz is also versatile and how the grapes are harvested determines the type of wine produced. If the berries are picked early, they will be used to produce light, citrusy wines with good acidity, but if left on the vine for longer, they will give a rounder, plumper wine that can be barrel-aged.

Quinta do Paral is located in the Vidigueira sub-region and had a few varietal and blended versions of Antão Vaz at the Wines of Portugal tasting. The estate is composed of 102 hectares of mature vines, olive groves, and cork oaks situated around the village of Vidigueira. Some of the grapevines are over 40 years old including Antao Vaz.  The Quinta do Paral Estate Bottled Branco 2018 is a blend of equal parts Antão Vaz, Verdelho, Vermentino & Viognier fermented in stainless steel; and exudes ripe, tropical fruit flavors with citrus and honey overtones. In contrast, the Quinta do Paral Vinhas Velhas Branco 2018 is richer where the 70% Antão Vaz and 30% Perrum are fermented in French oak followed by extended aging on lees. This is an excellent Burgundian-styled wine and made using 50+-year-old grapevines.
