Port wine in the context of "Douro River"

A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg.

Barrels have a variety of uses, including storage of liquids such as water, oil, and alcohol. They are also employed to hold maturing beverages such as wine, cognac, armagnac, sherry, port, whiskey, beer, arrack, and sake. Other commodities once stored in wooden casks include gunpowder, meat, fish, paint, honey, nails, and tallow.

The Douro (UK: /ˈdʊəroʊ, ˈdʊəruː/, US: /ˈdɔːruː, ˈdɔːroʊ/, Portuguese: [ˈdo(w)ɾu], Mirandese: [ˈdowɾʊ]; Spanish: Duero [ˈdweɾo]; Latin: Durius) is the largest river of the Iberian Peninsula by discharge. It rises near Duruelo de la Sierra in the Spanish province of Soria, meanders briefly south, then flows generally west through the northern part of the Meseta Central in Castile and León into northern Portugal. Its largest tributary (carrying more water than the Douro at their confluence) is the right-bank Esla. The Douro flows into the Atlantic Ocean at Porto, the second largest city of Portugal.

The scenic Douro railway line runs close to the river. Adjacent areas produce port (a mildly fortified wine) and other agricultural produce. A small tributary of the river has the Côa Valley Paleolithic Art site which is considered important to the archaeological pre-historic patrimony, designated a UNESCO World Heritage Site. Within Spain, it flows through the middle of the autonomous community of Castile and León, with the basin spanning through the northern half of the Meseta Central. The latter includes wine producing areas such as the Ribera del Duero DOP.

Dessert wines, sometimes called pudding wines in the United Kingdom, are sweet wines typically served with dessert.

There is no simple definition of a dessert wine. In the UK, a dessert wine is considered to be any sweet wine drunk with a meal, as opposed to the white fortified wines (fino and amontillado sherry) drunk before the meal and the red fortified wines (port and madeira) drunk after it. Thus, most fortified wines are regarded as distinct from dessert wines, but some of the less-strong fortified white wines, such as Pedro Ximénez sherry and Muscat de Beaumes-de-Venise, are regarded as honorary dessert wines. In the United States, by contrast, a dessert wine is legally defined as any wine over 14% alcohol by volume, which includes all fortified wines—and is taxed more highly as a result. This dates back to when the US wine industry only made dessert wines by fortification, but such a classification is outdated now that modern yeast and viticulture can produce dry wines over 15% without fortification (and German dessert wines can contain half that amount of alcohol).

Whisky or whiskey is a type of liquor made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, commonly of charred white oak. Uncharred white oak casks previously used for the aging of port, rum, or sherry may be employed during storage to impart a unique flavour and colour.

Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels.

California wine production has a rich viticulture history since 1680 when Spanish Jesuit missionaries planted Vitis vinifera vines native to the Mediterranean region in their established missions to produce wine for religious services. In the 1770s, Spanish missionaries continued the practice under the direction of the Father Junípero Serra who planted California's first vineyard at Mission San Juan Capistrano.

California wine production grew steadily after Prohibition, but was known mostly for its sweet, port-style and jug wine products. As the market favored French brands, California's table wine business grew modestly, but quickly gained international prominence at the Paris Wine Tasting of 1976, when renowned French oenophiles, in a blind tasting, ranked the California wines higher than the premier French labels in the Chardonnay (white) and Cabernet Sauvignon (red) categories. The result caused a 'shock' in viticulture industry since France was regarded as foremost producer of the world's finest table wines. This event contributed to expanding the recognition and prestige of vintners in the New World, specifically, the "Golden State".

Fortified wine is a wine to which a distilled spirit, usually brandy, has been added. In the course of some centuries, winemakers have developed many different styles of fortified wine, including port, sherry, madeira, Marsala, Commandaria wine, and the aromatised wine vermouth.

Mourvèdre (French pronunciation: [muʁvɛdʁ] ; also known as Mataro or Monastrell) is a red wine grape variety grown in many regions around the world. It is found in the Rhône and Provence regions of France, the Valencia, Alicante and Jumilla, Bullas and Yecla denominaciones de origen (DOs) of Spain, as well as the Balearic Islands, California and Washington and the Australian regions of South Australia and New South Wales, plus South Africa. In addition to making red varietal wines, Mourvèdre is a prominent component in "GSM" (Grenache, Syrah, and Mourvèdre) blends. The variety is also used to make rosé and port-style fortified wines.

Mourvèdre tends to produce tannic wines that can be high in alcohol. The style of wine produced from the grapes varies greatly according to where it is produced, but according to wine expert Jancis Robinson Mourvèdre wines often have wild game, or earthy notes to them, with soft red fruit flavors. According to wine expert Oz Clarke, young Mourvèdre can come across as faulted due to the reductive, sulfur notes and "farmyard-y" flavors that some wines can exhibit before those flavors mellow with age.
