Notes

Ensure that wheat is milled properly, sightly finer than the setting for barley.
Probably should move to a 2 gal strike and 2 gal sparge on a 3-gal batch.
Performed about 20 slow vorlauf re-circulations with a quart-sized pitcher (~15 minutes)
[!!! IMPORTANT !!!] Cut off the mash drain/sparge when total wort volume is around 2.5 gals and/or the brix is reading ~3. The most recent batch (while delicious) was lighter in color and mouthfeel than previously.
Prone to cloudiness. Use Irish moss.
Added 1 cup of cold brewed coffee to ~3 gal before kegging. This ratio should be increased.
