The multipliers
Kegs: fruit becomes wine at 3× base price (ancient fruit = 550 → 1,650g), vegetables become juice at 2.25×, hops become pale ale, wheat becomes beer. Jars: pickles and jelly at 2× base price + 50g. Kegs multiply harder; jars work roughly 2–3× faster (jars take 2–3 days, wine a week, juice about 4 days).
Match machine to crop
High-base-price fruit (ancient fruit, starfruit, melons, pomegranates) belongs in kegs — the 3× multiplier on a big number beats everything. Low-price bulky crops (corn, blueberries in bulk) often earn more per day in jars because of the speed. Hops are the keg sleeper: pale ale daily harvests keep kegs continuously fed.
Scaling the machine room
Keg and jar recipes are cheap (wood, copper/iron, stone) — the real constraint is space and crops. The shed is the classic keg warehouse: a fully loaded shed holds 137 machines. Put the machines beside the field, fill them the day of harvest, and let the cellar age the best wines to iridium for double price over two in-game months.
