Before I started, I bought HOMEBREWING FOR DUMMIES used off amazon for like $7.00, and it has been a really good resource. It quotes JOY OF HOMEBREWING quite often. It is about 150 pages, but it is a VERY quick read. I read the whole thing on a two hour plane flight. It is a good primer on homebrewing to get you used to all the lingo and the basic process. If you just rely on the recepie you get with your first kit, you are going to have trouble understanding some of the sections.
Oh, and if I had any advise for you (I started brewing in October 2010), they are these:
#1: Of all the equipment you buy, do not skimp on the brew pot!! If you have the $$$, go ahead and get a 7-15 gallon stainless steel brew pot to start. It might cost you an extra $100.00, but it is going to be the first thing you want to replace once you get going, so go ahead and get the biggest and best you can afford! Trust me, the second you start moving to partial grain or all grain, you are going to be consumed with wanting.......neeeeeeeeding.......a 15 gallon brew pot to make 10 gallon batches. I'm buying mine next week!
#2: Start off with extract kits. I'm on my 9th batch. I've done 7 extract kits and 2 batches of hard cider. Just now, I feel like I'm proficient enough to go ahead and start all grain brewing. The thing about extract kits is they are MUCH more forgiving if you make mistakes. You are going to make good, maybe not great, but good beer every time with an extract kit if you can follow simple directions. The extract kits are EASY, and you won't get frustrated beyond the inevitable impatience for the beer to be conditioned and ready for mass consumption!
All the posts you read of newbies with messed up batches are usually over eager, impatient, or think they are too smart for the directions. Follow the directions and you'll make good beer. THEN, once you have the basics down, move to all grain. All grain allows for more creativity, has the potential for much better beer, but also has the potential for small errors to lead to subpar batches. I for one wanted to have the system down before I headed to that level. Now I'm a robot from the time I start sanatizing to the time my brew is in the primary fermentation bucket. Get that part to where it is consistent and repeatable, and you'll start to make really good beer, even from extract kits.
#3: Also don't skimp on sanitizer. Sanatizing is one of the most important parts of the process, so make it as easy and proficient as possible. Get StarSan and a spray bottle. The bottle of StarSan itself is a little more expensive than IodoPhor and other rinse sanitizers, but a little StarSan goes a LONGGGGG way (1 oz per 5 gallons) and can be reused for a few weeks, plus, you just spray it (or soak in it) and let it dry, no rinsing, no staining (like the Iodine-based sanitizers). A 32 oz bottle of StarSan costs like $20.00, but it will last for a year! Don't buy the large thing of IodoPhor that cost like 8 bucks but lasts three brews.
Anyway, that's all of my suggestions for starting out! Best of luck!! I bet you have 50 gallons brewed by Xmas!!
