It seems like the process of making wine and similar is about using food ingredients to make a food product. Are questions about this subject disallowed for some other reason(s)?
The short answer is "we" don't want them here. The community has nearly unanimously decided they are off-topic since the original definition of this site.
Simply searching for "brewing" will find these and more:
Those interested in winemaking/brewing should be committing to the relevant Area51 proposal here: http://area51.stackexchange.com/proposals/1619/beer-and-wine-brewing
However, even that site isn't successful, they still don't belong here.
If you disagree and would like to argue your point, I kindly ask that you use one or more of the existing topics instead of this one.
If you're asking about the recent question stating that someone had made some champaigne (technically, they made a sparkling wine), and was asking about other alcoholic beverages they could make, I'm not the one who deleted it (I was waiting to see community response), but I personally thought it was inappropriate just because it was too broad.
Imagine I asked a question:
- I made a lasagne last week, and it was really good, what other Italian food can I cook?
- I made a pilaf last week, what other rice dishes can I make?
- I made a lentil curry last week, what other vegetarian dishes can I make?
All of these are blatantly too broad, and should be closed at the very least, if not deleted as well.
