Mark & Tess Szamatulski. I am looking it up now!
That’s the one. It is an excellent recipe book. I adjust the recipes and always use all grain. Another favorite from that book was my first homebrew “Blanc de Bruggs.” A Belgian Wit. I like it better than Hoegarden.
Just went to my bookshelf... It’s gone.
Taught my kids to homebrew. Now I must double check ingredients prior to brewing as supplies just disappear! Same with the good recipe books!
