Home brewing is becoming more popular… Check out this video from Time.
I enjoy wine but I haven’t gotten to the point that I want to make my own for consumption. The wine I buy for daily consumption is relatively inexpensive. I do not see myself as a craftsman of fine wine and taking the time to make something I want to do. There are kits to make wine and you have to keep the wine in a temperature controlled area, in the dark, agitate the container. With the money that I could spend buying the kit, I could have gone to a wine ship, or even a grocery store and found a nice inexpensive bottle of wine to have.
Granted people like making their own things. There are things I make that others would never even consider. There is a cult status of making wine and beer. Depending on the ingredients you may not really save that much money, but it is something that you can say you did yourself and gives you a pastime.
