Hops

 are a type of crop that is grown from hops seeds in the vineyard. Alternatively, they can be bought directly from the Miller. Hops are an improvable crop, meaning they have a variety of quality levels and can be improved upon with fertilizer. The quality of the hops will effect the quality of the products made from it. For more information, see farming.

Alchemy
Hops can be decomposed to solution and powder at the hand mixer and alchemy mill, respectively. Having unlocked Master of Alchemy produces one additional reagent at each workstation.
