I have 2 questions regarding the conversion of hte 6.72kg of Weyermann Bohemian Pils malt: 1) What do you recommend that I use as an extract? Amber Extract? I don't know enough. 2) Since the brewer is assuming 90% effeciancy, do I need to adjust my correction factor of 0.6 for dry, or 0.75 for liquid? I don't know much about all-grain and 90% seems to be an exceptionally good sugar extraction. Let me know if I'm at all on base. How big of a difference will there be between the grains? I recently tried one of these tasty beers and loved it and want to make something similar.
