As a bit of a 'leftover' from things gone past we still have over a hundred or so bottles of sherry that we cook with. And not that salted down cooking sherry, noooo, the good stuff. The stuff from Jerez Spain where Sherry comes from!

History of Sherry (by Wikipedia, edited even further by me)

Sherry is a fortified wine, made in and around the town of Jerez, Spain, and hence in Spanish it is called "Vino de Jerez". According to Spanish law, [1] Sherry must come from the triangular area of the province of Cádiz between Jerez, Sanlúcar de Barrameda, and El Puerto de Santa María.

Sherry differs from other wines because of how it is treated after fermentation. After fermentation is complete, it is fortified with brandy. Because the fortification takes place after fermentation, all natural sherries are dry; any sweetness is applied later. In contrast, port wine is fortified halfway through fermentation, stopping fermentation so not all the sugars are allowed to turn into alcohol and so leaving a sweet wine.

So I guess it would appear that we have 'the good stuff' as good as THAT can be at room temperature!

AND as stated in Beer Batter and Fish & Chips it makes a pretty darned good substitute for the beer in beer batter!
