Notes

Used 2/3 Reverse Osmosis water (5 gallon) and 1/3 Madison for a total of 28 l which brings the bicarbonates back from 364.0 to 120.

I thought I had the step temp at 70 C but my turkey bash meter is probably off by +4 C. Aimed for 19 but got only 17.5 l in fermentor (before adding starter).

pH dropped from 5.7 to 5.5, 10 and 20 minutes into mashing. It's temparture corrected. The chilled wort pH was still a high 5.6. pH 4.0 calibration solution measured 4.2 so values might be a bit too hi?

Hops were green when frozen back in September (3 months ago). I expect they went back in acids and I used more because the green ones must have been wetter, yes by a factor of 4.1.

850 ml starter from Wyeast 1762 (Belgian Abbey II) of the Potbelly Dodo Nov. '06. Was 2 weeks after it's hi krausen (late). Bubble every 20 seconds after 12 hours.

Cooler with manifold and spigot weighs 3.5 kg.

With the 5.6 kg grains there was 15.6 l in the mash tun filled up to the rim (~3 l water per grain kg dillution)

First taste is plenty bitter. Color looks dark redish/copper.
Moved fermentor to basement at hi spot where it's 65.5 F (18.6 C), down from 68 F iin kitchen.

Took back to kitchen for 3 days. Then put in 0C garage for 5 hours for the yeast to settle and raked into carboy.

First taste is sweet and fruity. surprisingly at FG 1.011 when kegged after 11 days. Final 7.3 Brix indicates 6.2% ABV which is in style defs.
