My first batch was the Imperial Pale Ale from Sam Calagione's Extreme Brewing book. It was my 2nd batch too.
I did 2 5-gallon batches back to back.... probably like 10 hours, lol.
I thought it was decent. Not nearly as complex to the craft beer I was used to. And I used chlorinated water without knowing better.
Besides being overly anal about sanitation, the recipe being edited poorly*, a boil over on the first batch, snow falling (Dec. 22nd in PA) on the second batch, not enough propane, wind kept blowing out the burner too so you had to stand outside, no idea about fermentation temp control.... it went pretty well. I stressed myself out, but I stressed my girlfriend out even more. I think she avoided brew days for the next few beers.
*The Extreme Brewing book has a huge error on that recipe. It says use "2 teaspoons (28 g) gypsum." Apparently an ounce is 2 teaspoons. Thankfully I got volumetric measurements elsewhere... that would have been a ton of gypsum for 5 gallons.
