A buildable distillery that would allow potatoes or berries for input. Then over time, produces vodka or gin, respectively. Mainly used as items for trade. Vodka and gin could be consumed by your colonists for some temporary mental boosts though.
JuliaEllie did a mod called RumWorld for alpha 7. I don't think she updated it yet though. I also am working on a wine production mod that is almost finished and only needs a couple adjustments before I release it. Mine adds in grapes and 3 types of wine, including berry wine. Keep watching the released mods section. I promise you'll see more alcohol related mods soon.
