Batch #48: Munich dunkel

Brewed the same day as the previous batch, timed much better than the last double-brew day. An easy-drinking dark lager to go with the Pilsner. Suffered from the same efficiency problem as the previous batch, too, but without as disruptive a result.

Timeline

Brew day: December 29, 2004

3:00: Mash-in with 3.5 gallons of 165F water.
4:05: Transfer to lauter tun onto 1 gallon 180+F foundation water.
Assume 1 pint/lb retention, giving 2 gallons + 1 pint free liquid.
notes fragmentary
4:22: Add 2nd sparge water batch of 3.5 gallons.
4:27: Finish second runoff.
5:00: Boiling! (refractometer give 8 brix? What's going on here?)
5:15: Add hops.
6:30: Add whirlfloc.
6:45: Start chilling.
6:50: Finally got the bubble out of the line. Wort flowing through Therminator fine.
6:55: Done transferring, wort at 66F.
7:20: 11.8 Plato (refractometer, about 1.0476), 1.046 (hydrometer)
7:25: Pitched and stowed in low-mid-50s basement.
8:00: Done with clean-up.

1/1/2005: seems to have stopped fermenting (?), may need to check on this one a bit more.

1/2/2005: took hydrometer and refractometer readings. Refractometer reads 7.8 brix, with the correction calculation from primetab.com, puts this at 1.022. Hydrometer roughly agrees, 1.020-24 (still foamy, can't shake all the bubbles, but it's in that range). Wort is gassy and yeasty, which means there's still hope that it's fermenting, just not kicking up a persistent head. Will let it rest a couple days and do the refractometer reading/calculation to see if it decreases....

1/5/2005: Took a refractometer sample, 7.8 Brix, corrected gives 1.021. Not much of a drop, so there may be a need for a rescue yeast :-(

1/10/2005: Another reading, no change. Added sachet of Saflager S-23, hope for the best.

1/14-15/2005: Another reading, no change. Kegged, and hope for the best.
