Congrats on taking the plunge into homebrewing. I remember my first batches and how much better my beer was by the time I was on my 3rd or 4th. :-) Sometimes several small adjustments can add up to a noticeable improvement. Things like getting to a boil quickly, getting cooled down quickly, covering the fermenter (out of sunlight), etc.. all of which are mentioned or hinted at above are fairly minor changes that add up to a big improvement in the final product. Those same things I added to my process pretty quickly. Other things, I haven't yet added.... For example, I haven't added a proper brew kettle...I can't do full volume boils, about 3.5 - 4 gallon is all I can manage (extract brewer, BTW). One of these days I will probably add one, but, probably not for a while unless I decide to give all grain a try. Anyway, good luck and enjoy!
