Wine making is really all about fermenting grape juice – although other fruit juices  fermented in the same way are considered (in some circles) to be wine, and some people would describe both cider and mead as wines. 

However, in this setting we will use wine to describe drinks made primarily by fermenting grapes and their juices.  In the modern world there are many different types of grape that are used to make wines, but to keep life fairly simple, I am going to assume that most wines are made from a local grape (lets call it Vitis Robusta) that thrives in a range of different environments, it matures to a medium sweet grape with a light red skin colour. As such it will work as a dessert grape and will make reasonable raisins when it is dried.  There are, however, other varieties of grape available, but they are more difficult to grow and need more care and greater skills to make wine from  :) 

Wines, generally, are about 10% to 12% ABV,

Local Wine

Most wines are a fairly bland rose wine made from the ubiquitous Robusta grape, the fermentation period is fairly short and it is often bottled early.  It must be drunk within one year or else it starts to get vinegary. It generally costs about 2sp for a pitcher.

Red Wine

Some vineyards specialize in growing a small dark grape that, when mixed with the local grape, can make a light red wine, this is considered a bit of a specialty product and is normally left to mature for a year or so before bottling.  It is seen as an expensive wine, charge about 3gp for a bottle.

White Wine

Some vintners use the local grape to make a dry white wine, however the process involves a lot of work separating the stalks and skins from the grape juice and then a period of maturation before the wine is ready for drinking.  It is seen as an expensive wine, charge about 3gp for a bottle.

Thunderbird Wine

Is a fortified wine which is made from a mixture of the local grapes and plum juice that is fermented into a deep red wine.  A small measure of aquvit is then added, which strengthens the mixture, fixes it and acts as a preservative.  Because it is fortified Thunderbird will last for more than a year,  however it should be drunk fairly quickly after opening.    Thunderbird is generally 15% to 18% ABV.  It is seen as an speciality  wine, charge at 1gp for a bottle.

Fine Wines

Fine wines are always imported from abroad, they can be Red, White, Rose, Fortified, Port-Wine, Sherry, Madera, Sack, Champagne or any other type of named wine that the PC asks for.  They always cost at least 10gp a bottle and more if they want a ‘prestige’ brand.
