A '''still''' must be lit to work, and the liquid will gradually change to the final drink over time. A '''still''' will grant passive skill-gain in [[beverages]] and [[cooking]] as it burns.
Still quality affects the fuel-burn efficiency. A still built to 50ql and fueled with one log, for example, will burn for about 1 hour and 15 minutes to 1 hour and 30 minutes. This burn time increases and decreases in conjunction with still quality.
To light the still, activate a [[steel and flint]] with a [[kindling]] in your inventory, then to fuel the still activate any item that can be used as [[fuel]] (for example, wooden items), right-click the still and select '''Burn'''.
