Barón de Terón Brut Nature: a Quality Sparkling Wine from Rioja

For decades, talking about bubbles in Spain meant talking about cava. Rioja, the region of great long-aging reds, also made sparkling wines, but without a category of their own to set them apart on the label.

Barón de Terón Espumoso Brut Nature belongs to that new generation. Bodega Virgen de la Vega makes it from 100% viura grown in the Rioja Alta, harvested by hand and early, using the traditional method of second fermentation in the bottle.

Bodega Virgen de la Vega is based in Haro, the capital of the Rioja Alta.

It is a quality sparkling wine from the DOCa Rioja in its driest version, the one that gets no sugar after disgorgement. It smells of green apple, pear and pastry, and on the palate it is both tense and creamy.

This guide covers what you should know before opening it: what the Rioja rules demand of its bubbles, how a sparkling wine like this is made, how to read the label, what temperature to serve it at and which dishes on the Christmas table it suits best.

Where it fits at Bodega Virgen de la Vega

For this selection, the winery sent three very different wines, all from the Rioja Alta:

• Barón de Terón: the house bubbles, made from viura, at around €14-15.
• ARVS 67 Blanco Crianza 2023: viura from vines over 30 years old, aged on its lees in French oak, at around €20-25.
• Vnvega 2009: tempranillo from their best vineyards, with 12 months in new French oak barrels, at around €15-20.

The sparkling wine and the white share grape and origin. The difference lies in the path: one is picked early to capture acidity and bubbles; the other ripens on the vine and then rests on its lees in wood.

Rioja’s quality sparkling wines: what the rules say

In 2017, the Regulatory Council of the DOCa Rioja approved the quality sparkling wine category.

The rules require the traditional method, with the second fermentation taking place in the very bottle that reaches the table. They also set a minimum of 15 months of aging in the bottle.

Above that there are two tiers: Reserva, with at least 24 months, and Gran Añada, with a minimum of 36 months and a mandatory vintage.

Rioja Alta: Atlantic freshness for the bubbles

In 1991, the DOCa Rioja became Spain’s first qualified denomination of origin, although its history as a denomination goes back to 1925. It stretches mainly across La Rioja, Álava and Navarre, along the Ebro valley.

It has three zones: Rioja Alta, Rioja Alavesa and Rioja Oriental. The Rioja Alta lies in the west, upriver, and is the zone most strongly influenced by the Atlantic.

That cooler climate extends ripening and protects the grape’s acidity. In a sparkling wine, acidity is the backbone: without it, the bubbles feel heavy and the wine goes flat after two sips.

Viura, the same grape as cava’s macabeo

Viura is the most widely planted white variety in Rioja. Outside the region it is known as macabeo, and it is one of the three classic cava grapes, together with xarel·lo and parellada.

It produces wines with discreet aromas, hinting at apple, pear and white fruit, and an acidity that stands up well to time. That is why it works both in aged whites and in sparkling wines.

For this sparkling wine, the harvest is manual and early, and the vineyard aims for moderate yields so the grapes keep their acidity and tension. Picking earlier means grapes with less sugar and more acidity: the base wine will have less alcohol and more freshness, exactly what the second fermentation needs.

If you wonder why a sparkling wine is harvested earlier than a still white, the answer is simple: the second fermentation raises the alcohol level, so it is best to start from a less ripe, more acidic grape.

How a sparkling wine is made by the traditional method

These are the stages of the traditional method, the same one the Rioja rules require for its quality sparkling wines, with the details the winery applies to Barón de Terón:

• Gentle whole-cluster pressing: the bunches go into the press whole and are squeezed delicately, giving a clean must without the bitterness of the skins.
• Base wine: that must is made into a dry, acidic still white, fermented at low temperature to preserve the aromas of viura.
• Tirage: the wine is bottled with a mixture of sugar and yeast, known as the tirage liqueur, and closed with a crown cap.
• Second fermentation: the yeasts consume that sugar inside the bottle; the carbon dioxide cannot escape and dissolves into the wine.
• Aging on the lees: the dead yeasts, the lees, rest in the bottle and contribute the pastry aromas and creamy texture. For Barón de Terón this lasts 17 months, above the 15 required by the Rioja rules.
• Riddling: the bottles are tilted and turned little by little until the lees settle in the neck.
• Disgorgement: the neck is frozen, the bottle is opened and the pressure pushes out the plug of lees; the bottle is then topped up and given its final cork.

What Brut Nature means on the label

After disgorgement, many wineries add the dosage liqueur, a mixture of wine and sugar that sets the final sweetness. In a Brut Nature, no sugar is added at that moment.

European regulations classify sparkling wines by their sugar content. These are the most common levels, from driest to sweetest:

• Brut Nature: less than 3 g/l and no added sugar.
• Extra Brut: up to 6 g/l.
• Brut: less than 12 g/l.
• Extra Dry: between 12 and 17 g/l.
• Dry: between 17 and 32 g/l.
• Medium Dry: between 32 and 50 g/l.

Choosing Brut Nature means trusting the grape: with no sugar to soften it, the acidity and the fruit are laid bare.

Tasting notes for Barón de Terón Espumoso Brut Nature

In the glass, stage by stage:

• Appearance: pale yellow with greenish reflections and fine bubbles.
• Nose: green apple, pear and citrus, with notes of pastry and yeast.
• Palate: tense and creamy at once.
• Finish: long, with hints of fresh fruit and toasty nuances.

The greenish reflections and green apple speak of youth and an early harvest. The pastry and yeast are the mark of the lees.

“Tense” and “creamy” sound like opposites, but they describe a good Brut Nature well: the acidity sets the pace, and the fine bubbles, integrated after aging, leave a soft sensation on the palate.

The winery’s figures confirm it: 12% vol., a total acidity of 6 g/l and 6 bars of pressure in the bottle, the usual figure for a traditional-method sparkling wine. It is a wine light in alcohol, with acidity as its backbone and bubbles with just the right energy.

How to serve it without losing the bubbles

Serve it between 6 and 8 °C. The most practical way is an ice bucket with water and ice for about 20 minutes: it chills faster than ice alone.

Forget the narrow flute. A white wine glass or a tulip glass leaves room for the pear and pastry to come through.

To open it, remove the wire cage while holding the cork down with your thumb. Tilt the bottle and turn the bottle, not the cork: it should come out with a sigh, not a bang.

Pour in two stages: a short first splash, wait for the foam to subside and fill up to halfway. That way it does not overflow and the bubbles last longer.

Pairings: from starters to rice

It goes well with oysters, seafood, white fish, tempura, creamy rice dishes and young cheeses. Here are some specific combinations:

• Raw oysters: the salinity of the sea and the acidity of the wine reinforce each other, with no sugar getting in the way.
• Boiled prawns or king prawns: the natural sweetness of the shellfish contrasts with the dryness of the sparkling wine.
• Vegetable or prawn tempura: the bubbles cut through the fat of the frying with every sip.
• Grilled sea bass or hake: delicate white fish that call for a wine without oak.
• Creamy mushroom rice: the acidity cuts the richness of the rice and the pastry notes connect with the mushrooms.
• Fresh Camerano cheese: the goat’s cheese from Rioja with protected designation of origin, mild and lactic.

Avoid sweet desserts, nougat included. Next to something sweet, a wine without sugar tastes sour and bitter; for the final toast, serve it before the polvorones arrive.

At Christmas, think of it as more than the toasting wine. Open it with the seafood starters and let it accompany that whole first part of the menu.

Rioja sparkling wine or cava: how they differ

They share the traditional method and, often, the same grape. Even so, they are not the same:

• Origin: cava is made mostly in the Penedès; Rioja’s quality sparkling wine only within the DOCa Rioja.
• Grapes: cava relies on macabeo, xarel·lo and parellada; Barón de Terón is 100% viura.
• Minimum aging: 9 months for a basic cava, against 15 months for Rioja sparkling wine.
• Landscape: the Mediterranean climate of the Penedès against the Atlantic freshness of the Rioja Alta.

If you usually buy cava, serve both side by side with the same starter. It is the best way to discover that Rioja’s viura has its own accent.

How long it keeps and how to store it

A sparkling wine that has already been disgorged is ready to drink and gains little with the years. It is best enjoyed in the months after purchase, while it keeps the liveliness of green apple.

Store it in a cool, dark place at a stable temperature, away from the kitchen and from light. Do not leave it for weeks in the fridge: the dry cold dries out the cork and the vibrations of the motor do it no favors.

If you have half a bottle left, close it with a stopper made for sparkling wines and put it in the fridge. That way it keeps its bubbles for a day or two.

Price and who it is for

Its indicative price is €14-15, and the winery’s shop sells it in cases of three and six bottles. In a restaurant, a sparkling wine in this range usually sits on the list between €28 and €40, depending on the venue.

It is for those who want to step away from the usual cava without giving up the traditional method, for those who prefer dry, food-friendly sparkling wines and for a Christmas dinner where seafood opens the meal.

It also makes a good gift for the Rioja enthusiast who only knows its reds. Few things surprise as much as Rioja bubbles served blind.

What if this year the toast began with the oysters and did not wait for the nougat?
