I used S-04, fermented this at 65F but didn't do the temp. raise. I also used Great Western NW pale ale malt, omitted the gypsum and it turned out very good. Close enough for me, the pale ale malt really is the key, gives it great body. This will be going on my regular rotation of brews. Next time I'll try adding the gypsum, but maybe only half as much. After about six weeks grain to glass this turned out to be a smooth, balanced pale ale.
