Since we now have a lovely mixture of alcohols, why not improve upon this by adding more.
1. Add grapes (and maybe barley)
2. Add a distillery
3. By boiling "soup" beer that has already been fermented as much as possible, you should get whiskey, distilling for long periods of time gets stronger alcohol to the point it might become a viable fuel. Distilling wine makes brandy but distill it for too long, and it just tastes nasty (nausea and blindness).
4. Add wine, whiskey, brandy, and maybe cider and calva (like they have in Milenaire)
5. Unrelated but let a macerator turn cobblestone into gravel and add a sifter that can sort items and turn gravel into sand and flint
If cider is done, then unfermented drink of cider and water would be non alcoholic and restore hunger and/or hearts and stronger alcoholic cider could be able to be distilled into Calva. That is what they do in Millénaire.
