I've not tried this but it is supposedly very much like S.A. S.A.
5 lbs Pilsner
4 lbs Wheat Malt
1 lbs Flaked Wheat
.5 lbs Cara-Pils
.75 oz Hallertauer 4.8% AA 45 min
.25 oz Hallertauer 4.8% AA 60 min
.5 oz Grains of Paradise 20 min
1 oz Lemon Zest 20 min
Belgian Witbier yeast
If I made this as a clone of Sam Adams Summer Ale I would most likely use White Labs "East Coast Ale" as I don't remmeber S.A. as having a Wit like yeast character. In my experiance East Coast Ale is slightly tart and it is called the "Brewer Patriot Strain" by White Labs, so I think it would be perfect for this clone.
