Washback
A washback (also called a wash back or fermentation vessel) is a large container used in distilleries where fermentation happens - this is where grains or other ingredients are mixed with yeast to create alcohol before distillation. It's like a giant tank where the first major step of making spirits takes place. Traditionally made of wood (especially in Scotland), modern versions can also be stainless steel. Understanding washbacks is important in spirits production because they affect the final taste of products like whiskey, and proper management of these vessels is crucial for quality control.
