Sherry in the context of "Casks"

An oak is a hardwood tree or shrub in the genus Quercus of the beech family. They have spirally arranged leaves, often with lobed edges, and a nut called an acorn, borne within a cup. The genus is widely distributed in the Northern Hemisphere, with some 500 species, both deciduous and evergreen. Fossil oaks date back to the Middle Eocene. Molecular phylogeny shows that the genus is divided into Old World and New World clades, but many oak species hybridise freely, making the genus's history difficult to resolve.

Ecologically, oaks are keystone species in habitats from Mediterranean semi-desert to subtropical rainforest. They live in association with many kinds of fungi including truffles. Oaks support more than 950 species of caterpillar, many kinds of gall wasp which form distinctive galls (roundish woody lumps such as the oak apple), and a large number of pests and diseases. Oak leaves and acorns contain enough tannin to be toxic to cattle, but pigs are able to digest them safely. Oak timber is strong and hard, and has found many uses in construction and furniture-making. The bark was traditionally used for tanning leather. Wine barrels are made of oak; these are used for aging alcoholic beverages such as sherry and whisky, giving them a range of flavours, colours, and aromas. The spongy bark of the cork oak is used to make traditional wine bottle corks. Almost a third of oak species are threatened with extinction due to climate change, invasive pests, and habitat loss.

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.

Vernaccia is a white wine grape that is found in many Italian wines but is most commonly associated the Tuscan wine Vernaccia di San Gimignano. Ampelographers have determined that the Vernaccia vine has many clonal varieties but is unrelated to some Italian vines known as "Vernaccia" such as the Sardinian varieties used in the Sherry-like wine Vernaccia di Oristano, the Trentino-Alto Adige/Südtirol red wine grape known as Vernatsch or the black grape used in the red sparkling wine of the Marche Vernaccia di Serrapetrona. A possible reason for this is that the root of the name Vernaccia translates to different Italian vernaculars and other languages (such as German and Sardinian) and can apply to any local grape.

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).

Vin Santo (Italian: [vin ˈsanto]; lit. 'Holy Wine') is a style of Italian dessert wine. Traditional in Tuscany, these wines are often made from white grape varieties such as Trebbiano and Malvasia, although Sangiovese may be used to produce a rosé style known as "Occhio di Pernice" or eye of the partridge. The wines may also be described as straw wines since they are often produced by drying the freshly harvested grapes on straw mats in a warm and well ventilated area of the house (however, several producers dry the grapes by hanging on racks indoors). Although technically a dessert wine, a Vin Santo can vary in sweetness levels from bone dry (like a Fino Sherry) to extremely sweet. While the style is believed to have originated in Tuscany, examples of Vin Santo can be found throughout Italy and it is an authorised style of wine for several denominazione di origine controllata (DOC) and indicazione geografica tipica (IGT).

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.

Trifle is a layered dessert of English origin. The usual ingredients are a thin layer of ladyfingers or sponge cake soaked in sherry or another fortified wine, a fruit element (fresh or jelly), custard and whipped cream layered in that ascending order in a glass dish. The contents of a trifle are highly variable and many varieties exist, some forgoing fruit entirely and instead using other ingredients, such as chocolate, coffee or vanilla. The fruit and sponge layers may be suspended in fruit-flavoured jelly, and these ingredients are usually arranged to produce three or four layers. The assembled dessert can be topped with whipped cream or, more traditionally, syllabub.

The name trifle was used for a dessert like a fruit fool in the sixteenth century; by the eighteenth century, Hannah Glasse records a recognisably modern trifle, with the inclusion of a gelatin jelly.

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.
