Sherry Styles: Oloroso (No Flor, Fully Oxidative, Dry)

The first rules governing the Denomination were the Regulations of the Guild of Raisin and Grape Harvesters of Jerez, established by the town council on 12th August 1483. The norms of the Vintners' Guild restricted the ageing of wine, which it considered a speculative practice. In 1775 local producers began the so-called 'Extractors' Action', a lawsuit that concluded several decades later with the abolition of the Vintners' Guild. The solera and criadera system, bodega architecture and Jerez wines as known today began to take on their distinct characteristics in the late 18th century, and the so-called 'Cathedral Bodegas' began to appear in the first half of the 19th century. In 2000 the Consejo Regulador created two categories of Sherry of Certified Age, V.O.S. and V.O.R.S., for wines over twenty and over thirty years of age.

• The Vintners' Guild's norms favoured the trading of young wines and hindered producers from selling the type of wine for which demand was increasing
• The criaderas and solera system arose from the prolonged storage of wines from different harvests and the need to supply a product consistent in quality
• González Byass, Domecq, Harveys, Williams & Humbert and Sandeman are among the firm names that began or consolidated in the first part of the 19th century

Ten towns have vineyards in the Denomination: Jerez de la Frontera, El Puerto de Santa María, Sanlúcar de Barrameda, Chiclana de la Frontera, Chipiona, Puerto Real, Rota, Trebujena, San José del Valle and Lebrija, the last belonging to the province of Seville. The average annual temperature is 17.3ºC, with between 3,000 and 3,200 hours of effective sunlight and rainfall averaging six hundred litres per square metre per year, usually falling in autumn and winter. The characteristic soil, albariza, is a limestone soil rich in calcium carbonate (up to forty percent), clay and silica, and its moisture-retaining power stores each winter's rainfall to nourish the vines during the dry months.

• The Consejo calls albariza the best type of soil for producing Palomino grapes
• The DO has three soils: albariza, clays and sands
• Two prevailing winds mark the growing season: the cool, humid Poniente from the west, under which humidity can reach ninety-five percent, and the hot, dry Levante from the south-east, with humidity of around thirty percent

Seven varieties are authorised for the DO's wines: Palomino, Listán Blanco or Palomino Fino, Pedro Ximénez, Moscatel de Alejandría, Beba, Perruno and Vigiriega. Oloroso is made from palomino grapes. After fermentation, tasters classify each batch of new wine, and batches that show greater structure, or gordura, are earmarked from the very start for oloroso, their tanks marked with a circle symbol. Segunda yema must, whose structure derives to a greater extent from solids, is used to produce wines better suited to oxidative ageing. Wines classified as olorosos are fortified to at least 17%, and above 17% by volume not even the flor yeast cells can survive. A second route exists: wines first classified for biological ageing whose flor proves less vigorous, or disappears, during the sobretablas stage are fortified to 17% so that oxidative ageing may give rise to oloroso sherries.

• Wines classified for oxidative ageing are identified as future olorosos from the very first day, which is not the case for wines classified for ageing under flor
• The American oak 600 litre butt, also known as a bodega butt, is the preferred and most widely employed cask today
• Merma, the evaporation of wine through the butt, accounts for losses of 3 to 5 percent per year and continually concentrates the wine's other components

González Byass's Alfonso is a dry oloroso with a minimum of 8 years in American oak cask following the traditional Solera system, made from 100% Palomino Fino at 18% vol. Lustau, whose origins date back to 1896 and which merged with the Luis Caballero company in 1990, makes Olorosos from 100% Palomino that include Don Nuño, aged for 12 years in Bodega La Campana in Jerez de la Frontera; Emperatriz Eugenia, aged for 15 years, from a solera founded by Emilio Lustau in 1921 to commemorate the visit to Jerez of Eugenia de Montijo, the last Empress of France; and an Oloroso VORS with an average age of 30 years. Equipo Navazos bottles wines drawn from individual soleras and butts under its 'La Bota' label, in limited, numbered editions with the date of the saca identified, and its list includes several Olorosos.

• Lustau's Oloroso VORS comes from a selection of 9 casks made by Manuel Lozano, former Cellar Master of Lustau, among the oldest solera casks
• The Oloroso VORS is bottled without any kind of treatment, drawn straight from the barrel
• Equipo Navazos began in December 2005; its La Bota editions include Nº14 de Oloroso Viejísimo 'Bota NO' and Nº28 de Oloroso 'Bota Punta'

The pliego de condiciones of the DOP Jerez-Xérès-Sherry, consolidated under the Order of 13 May 2026, defines Oloroso as a wine of exclusively oxidative ageing after the disappearance of the initial veil of flor, and requires vinos generosos to have a minimum average ageing of two years. It sets Oloroso at 17 to 22% vol with no more than 4 g/L of sugar, and all vinos generosos are considered dry wines. Generosos with qualified age may reach up to 9 g/L of sugar through the concentration of long ageing, subject to an acidity condition, and oxidatively aged wines may exceed the alcohol levels in the pliego's table. Sweetened blends form a separate group, the vinos generosos de licor, in which Medium carries from 4 to under 115 g/L of sugar and Cream from 115 to 140 g/L. Cream is a blend of Oloroso with an amount of Pedro Ximénez, commonly known as Sweet Oloroso. In general terms, the quota system requires that for each litre of sherry sold, three litres remain in stock in the ageing bodegas.

• V.O.S. ('Vinum Optimum Signatum', Very Old Sherry) certifies an average age of over 20 years and V.O.R.S. ('Vinum Optimum Rare Signatum', Very Old Rare Sherry) over 30 years; for each litre sold, at least 20 or 30 litres must remain in the ageing system
• Certified age is granted to each individual saca, not to a brand, after an independent Tasting Committee and laboratory analysis of parameters such as Carbon 14
• Sherries with an Indication of Age of 12 or 15 years are certified for the whole criaderas and solera system, with annual sales quotas of one-twelfth and one-fifteenth of the stock held

Jerez de la Frontera is a city of around 200,000 inhabitants where sherry wines share the stage with flamenco and horse breeding. Bodegas in Jerez can be as tall as 15 metres at their central arch, and their floors are covered with albero earth that can be sprinkled with water to regulate temperature and humidity. Lustau acquired six 19th century bodega buildings in the centre of Jerez in 2000, which today house its principal ageing bodegas, and calls itself the only winery producing wines in each of the three cities of the Sherry triangle. From the middle of the 19th century a trade ran in empty casks from bottling lines in the south of England to Scottish distilleries. After the Consejo prohibited bottling outside the production zone at the start of the 1980s, cooperages, bodegas and distilleries formed commercial alliances to keep seasoned casks in supply.

• Serve Oloroso at 12 to 14ºC in a white wine glass; its composition allows it to be stored in open bottles for months
• The Consejo calls Oloroso the most suitable wine for red meat and game, and pairs it with meat stews and casseroles, wild mushrooms and well cured cheeses
• Bodegas season casks for the whisky trade using exclusively wines from the vineyards of the Denomination
