Especially to dogs--even just a small portion of raw dough can lead to a reaction. This arose back when we were still storing foods. The ability to consume rotting fruit is pretty important. Nowadays we are regressing back to small-batch brewing. Up until maybe 20 years ago, the majority of alcohol in the u. s. was from 3 companies.

Intentional brewing 101 kill the seeds but preserve the enzymes.
