I am not familiar with homebrewing. Can you tell me anything about the process?
First of all, it's small scale beer brewing for personal and non-commercial use.
Is it actually done is someone's home?
Yes and it has been done on the domestic level for thousands of years prior to commercial production.
HaHa Is this like moonshine?
I guess you can compare it to that somewhat. Ironically, it was always tradition for women to do the brewing because it was considered a part of baking or kitchen duties.
Wow! That is funny for some reason. What exactly was involved in the process?
Both grape wine and beer was cultivated.
Did they grow their own grapes?
Yes and the growing of grapes is viticulture and there are many varieties.
