I know of several people that brew their own beer and make their own wine, both of which i love, but the process has always seemed way too complicated for me to even attempt.
I haven't done it recently but I have brewed my own ale. Lot's of fun.
Corrados in Clifton NJ has a great store for wine and beer brewing supplies. It's huge.
I'm in Hunterdon County (Whitehouse Station). I brew beer, typically parti-gyle all-grain. I also have a mobile brewery for those who don't want to invest in the equipment themselves.
