here are my thoughts on this
0. new concepts
Thirst vs drunkenness
Thirst becomes the result of a moving activity (climbing, foraging, running). This would separate working activities (using Phlegm) from moving around activities (using Beverages).
For a constant threat just standing around so to say living could also increase thirst. If you didn’t drank enough you lose consciousness. (after a while reappearing on the homestead with some thirst quenched – due to sleepwalkingly sucking water out of the soil – or so, not permadead you no?)
Alcoholics would increase drunkenness. As mentioned before this is relevant because people at the time of Salem were drunk all the time

Drunkenness would help you fight fear that you might experience if you engage a bear. But also decreases your humors Yellow and black bile. It makes it thus difficult to learn and fight while you are drunk. (what a surprise!). It could also not just reduce the black bile but decrease the regeneration of it if you consume food.
1. Beverages inside Gluttony
You drink a beverage while in gluttony and it reduce full & fed up time as well as restore “food group-percentage”. I know that there are already foods for this but it is mostly part of our culture to assume some food and some drink fit together.
To keep it “simple” let’s have not for every food group a beverage group. It should be sufficient to take famous combinations like
tea & coffee (bitter) reduces time/restores sweat stuff like berry pastry
red wine -> red meat
white wine-> seefood
schnapps -> kritters and insects …
In Addition there could be the concept of an aperitif. It must be consumed before the next food Item. It would only affect the next one or few of the specific food group from which it is the counterpart.
2. Beverages outside Gluttony
Different categories of beverages have different abilities.
Non Alcoholic:
2.1. Juce:
-quench thirst
-regenerates humors
made from: Pumpkins, Berries, Carrots, Tomatoes (Apples, cherries – Yeah!)
2.2. Tea:
-quench thirst
-counterpart in gluttony
-Allows you to sit in a rocking chair or in front of your house sip on it for a while and regenerate humors (later probably with pipes). It is a great addition for RPG and help to feel like you are really relaxing after hard day work. For the balance in game it would exchange time you need for searching food items with time to drink tea.
(Similar to the bed where you can sleep and slowly regenerate (online off course) the rocking chair could be in “cabinet maker”)
made from: herbs, dried fruits, and of course tea (boston)
alcoholic
3. Beer:
-add to drunkenness
-quench thirst
-regenerate humors
-give points in gluttony
-counterpart in gluttony
I remember that the railroad layers in early British industrial time where feed with bread and beer so it has obviously humor increasing abilities. I would tread I like normal food with the addition of weak alcoholizing effects.
I want to have hop. It would be a smaller field like 2x2 and would need wood to construct it because it grows on a scaffold. (I am so excited for such a thing)
new structures: big barrels
4. Wine
-add to drunkenness
-quench thirst
-counterpart in gluttony
-regenerates humors
Wine plants should behave like bushes. Maybe they could just be plant in this new 2x2 field to give it additional fertilizer and so on.
new structures: wine press, big barrels, wine bottles or glasses, vine cellar a 2x2 door in the floor of a building could lead to a cellar with the same dimensions like the building above
5. schnapps
-add to drunkenness
-not quenching thirst!
-counterpart in gluttony
-may give some inspiration
Everything that has to go through some kind of distillation or even double or repeated distillation to refine its quality
Vermouth, pure alcohol, fruit schnapps (Mirabelle and pear), brandy
Special ones (multiple times distilled, with aspecial caterpillar inside or from a nice cactus) helps you regenerate inspiration
4. Introducing fermentation
With alcohol there comes fermentation.
new kinds of food that has to be fermented like (cucumber, onions, pepper)
pickled gherkin
new plant: cucumber + salt in a fermenting pot (made from clay in kiln stand on the ground like urn)
normal gherkin (acid)
the whole animal thing (eggs, milk from later possibly coming cows and sheeps for cheese…)
vinegar – salad dressing
mead (made from honey which I will describe later in my second edition of “beekeeping in detail”)
water kefir to introduce some kind of lemonade or ginger ale (in earlier times alcoholic). This could be an early game alcoholic (fermenting fruits (in a clay pot) and hoping you get the culture of bacteria right – chance of failure) if you have the right culture you should keep it as the gelatinous “kristalls” for further use. Or even use purity system on the yeast and bacteria cultures introduced … I am amazed by my own ideas.
just recognize that water kefir in English is Tibicos…oO

And with drinking comes urination
making colored clothing (blue jeans

Isatis tinctoria + urine in a trough to make the famous indigo color for otherwise white shirts…
Urine with some influence on the tanning liquid or as tanning fluid itself (I think urine was used at some time in history for it)
extracting red and yellow color from flowers (red devil, sunflower)
