I want some home-made wine and I live in Scranton, PA?!
Answers: Where can I buy some good, home-made vino? It's like some sort of underground club or something: if you don't have some sort of "connection," you can't find it to buy. HELP! I want some!
It is illegal to sell your homebrew without a federal and or state permit. If anything, what you have heard about are swaps. In the homebrew community it is quite common for brewers to swap some of their homebrew for another homebrewer's. It's not really much of an underground club, if you were to start homebrewing (whether it's beer, wine, cider, etc.) and join a local homebrew club or a website like http://www.homebrewtalk.com then you would probably be able to swap what you make for other people's brews.
If you want more information on homebrewing, or start homebrewing yourself and are interested in a swap, feel free to email me.
Make it.
