Artisan Goods produced by a keg will always be more valuable than the input materials. Their final value is not affected by the quality of the ingredient. So, compared to selling the raw crops, a keg will produce profit faster if normal quality (not silver or gold) crops are processed. However, sometimes a keg will still produce profit faster if processing an expensive gold quality crop than it would processing a less expensive normal quality crop.

For example, processing a silver quality Pumpkin is more profitable (per time spent) than processing a normal quality Red Cabbage, but processing a gold quality pumpkin is less profitable then either. Processing Starfruit always generates profit faster than Hops, regardless of crop quality.  All cases are considered below.

The rate of productivity of a keg is: ([Sell Price of Artisan Good] - [Sell Price of Input Produce]) / [Processing Time]<ref name="timing caveat">Caveat: presumably, Artisan Goods that complete processing during the night incur "wasted" time until morning, when the player can refill the Keg. This potentially undermines the practical productivity rates of Beer and Pale Ale, which require more frequent refills and are more likely to be delayed by finishing at night.</ref>
