Best beer I've ever made.
Fixed mash ph with Citric acid, and then added a little bit more post boil to get the beer ph down to about 4.9. This was suggested to me by a friend who is a professional brewer, on the basis it will really help ensure a crisp lager.
It worked! Very crisp! To my tongue the citric acid is quite noticeable, and a very pleasant yet subtle modification to a traditional style. Lends a slightly more modern taste to it, but only slightly - it still tastes very much like a European light lager, in the range of czech pale/munich helles.
OG was 1.042 which is a little short, and finished exactly at 1.011. Beer in no way tastes like it missed out on those 3 points - I can't believe how good this tastes.
