I did my first AG BIAB batch on 01/09/10; it fermented for 3 wks, conditioned for 3 wks, has been in the fridge now for 3 wks. The problem is some beers taste good, others have a hot alcohol taste. The bad ones have NO head, but are carbed. This was a 3.5 gal batch, the recipe is:
5.00 lb::American two-row
1.00 lb::Crystal 60L
0.25 oz::Sterling::Whole::5 minutes
0.25 oz::Sterling:ellet::20 minutes
0.25 oz::Sterling:ellet::60 minutes
Safale US-05
Mashed @ 158° for 60 minutes (too high?), did not have my wort chiller yet, took 2.5 hrs to cool outside in 0 deg day. The yeast was pitched @ 78° (also too high), but the wort was down to 68° w/in 4 hrs. Fermention was steady @ 62°.
I used my well water (tested by Ward labs) diluted 20% w/RO water, I used the E-Z Water Spreadsheet & added Gypsum & Epsom salt to get all mineral levels w/in the acceptable range. I did not get the complete home test, just the basic, so I don't have my iron level. But, I have very hard water that stains clothes & plumbing (iron?).
What would cause this off flavor, & why would some bottles be good. I brewed 14 extract batches before this with very good results (all RO water). Thanks for taking the time to read this very long post.
