I'd like a mod that re-structures alcohol production to increase authenticity and difficulty, requiring fresh water and fuel as additional inputs. This would mean defining a difference between a brewery and a true distillery, turning this vital aspect of the dwarven economy into a more nuanced industry.
Fruit-derived drinks (wines) would be produced at a brewery identically to the current system. Simple grain alcohol (Beer, ale) would require water as an additional reagent, as well as a heat source (with wood, charcoal or coke being usable). A distillery would turn brewed alcohol into stronger distilled spirits, requiring fire safe materials for construction and fuel for operation. It's true, however, that common practice is to brew alcohol meant for direct distilling in the still itself, so the still workshop could either combine brewery and still functionality, or simply take brewed alcohol as a feedstock, or some combination of both. Perhaps it may be best to have only one workshop, that can both brew and distill. Production of whiskey would be: grain + water + fuel -> beer; beer + fuel -> whiskey.
Produced spirits (proper rum, whiskey, vodka, etc) could be useful as a high-value trade good, medical disinfectant, and be highly flammable, if that's possible. In addition to being more pleasing to your dwarves. While we're at it we may as well make cooking require fuel (again, wood, charcoal or coke should be suitable). Would make fortresses depend much more on access to both fresh water and reliable fuel.
I know very little of modding for DF, so my questions are: How feasible is this as a mod, and is there already anything out there similar to this?
Would this be as simple as coming up with a few new reactions?
Would it be possible to have fermentation take an amount of time (days to weeks), instead of the current situation where it's done as soon as your brewer slaps the ingredients together?
Hope this post makes sense.
