Have no fear though, when things go wrong, it provides you with another opportunity to get it right.
In my first attempt of cloning a Guinness Dry Irish Stout, I started off by using Jamil Zainisheff’s Dry Irish Stout recipe from Brewing Classic Styles as a base. That beer turned out fantastic. I made no water adjustments to it, and the final result was quite delicious. For the second round I wanted to try and match the highly alkaline water of Dublin, as well as add some acidulated malt to try and emulate the Guinness ‘twang’.
Water chemistry in brewing is a very complex subject, one that I certainly haven’t mastered. Most home brewers would say don’t even bother messing with it, but I want to find out how to make the best beer possible. I don’t want to make ‘good’ beer, I want to make ‘great’ beer, so I will mess with everything I can until I find out how to, even if that means having some casualties along the way.
