IMO, before you start, READ,READ,READ as much as you can on brewing science. Also, and again this is just my opinion, go straight into all grain brewing. Thats not to say there is anything wrong with extract because there isn't,BUT, all grain is where you will eventually end up. I brewed extract back in the late 80's and made ok beer but not good enough to spark the intense interest I now have for brewing and i quit. I started brewing again about 6 years ago and it is an obsession! I brew about once or twice a month. If there is a craft brewer near you then go introduce yourself and volunteer to work. That dirty grunt work will give you some great insight. If there isn't a brewer, join a brew club! One last opinion, if you have some fairly deep pockets, go electric and don't settle for a system less than 10 gallons. When I started brewing again I went all grain with a keggle, 2 -10 gallon gott style coolers,carboys and the such and was garage bound weather permitting. Now I have a pretty awesome 20 gallon electric system in my basement and I never tire of brewing.It really is a love affair and one that the wife enjoys too. GO FOR IT!! You won't regret it!
