Having now made ales for some years, I am going to be branching out this next week and trying to brew a lager. My first batch will be a classic Pilsen. Some of the warnings that I have read seem to indicate that due to its sheer simplicity of ingredients, it is not as forgiving or able to mask off flavors as in the heavier ales. Too, I have never attempted lagering or brewing with real lager yeast. are there any areas or differences that I need to be aware of as I make my preparations? Anything specifically NOT to do?
