Much like I said about the suggestion to add wine, I love the idea, and can see a number of spin offs from it as well. Spirits can be used by your healers to disinfect wounds and make stronger medicines. It can be combined with your orchards to make peach brandies. And alcohol (as well as vinegar from the winery) can be used to preserve more foods, like pickled eggs, fish, and greens. And that just opens the door to specific “pub snacks” for an even further upgraded pub.
Overall, great idea though. Thanks for the suggestion.
More importantly, the majority of ‘spirits’ are from Grains or Fruit, many of which are already in the game:
Brandy, from any number of fruits like apples (Calvados) or pears, or wine
Whiskey, from Barley, Wheat, or Buckwheat (Japanese Shochu)
Vodka, from Wheat
A Distillery would require not only the ‘raw material’ of grains or fruits or even vegetables, but also large quantities of Firewood and some input from your Forges or Blacksmiths to build the distillation vats in the first place, so this would be a High Tier undertaking, with distilled spirits possibly being a Tier 4 or 5 Luxury - and a really lucrative trade good.
