First wort pulling 1.080, shooting for 1.048 preboil. Actual preboil gravity is 1.042 with 7 gallons in the kettle, so I'm looking at 1.050 with 6 gallons postboil. Turns out, with boil down to 5.75 gallons, I pulled 1.055 for OG, so that is good. I left 0.5 gallons in the kettle due to a malpositioned dip tube, so I lost that. Pitched 375mL yeast slurry. Aerated 45 seconds, producing lots of foam so that is max time likely otherwise foam would pour out carboy. 11/10/17 - Fermentation started about 5 hours after pitch. High krausen, about 3 inches of foam, at 10am on 11/10. Bubbling is rapid but not extremely so. Looking good. 11/12/17 - Primary fermentation is essentially done. There's a bubbly layer of foam on top similar to what my Xmas beer had; best way to describe it is almost gelatinous, which I've only seen when I've aerated so perhaps there's a connection. I will wait and see. 11/18/17 - Foam has mostly subsided. I'm tempted to take a hydrometer sample but I'll leave it for another 10 days or so for when I'm going to bottle. 11/27/17 - Ready to bottle. Will prime to 2.4 volumes. Hydrometer reads 1.012 and pycnometer pulled 1.0121, so I am feeling confident about using the pycnometer for official OG and FG readings. Hydrometer sample tasted of bread and nuts, faint yeast fruitiness on the back end. It almost seemed to lack depth so I'm hoping that, with carbonation, it will round out.

Gravity Estimates

Based on boiling 7.00 gallonsliters at 1.042 for 60 minutes, this will decrease your wort by 1.00 gallonsliters, bringing your after boil OG to 1.048.

You wanted an OG of 1.055. It looks like it will be under.

Notes:

Poured with minimal head that dissipated quickly. Aroma is wheat bread and yeast primarily with a slight nuttiness. Color is brown and, when in the light very dark, translucent amber. Flavor is toasty malts, wheat bread, and finishes with a nutty chocolate flavor. Mouth feel is good, not too dense or watery. Carbonation is lacking, so may not be fully primed. The clarity of this is surprising as it's as clear as professional brews yet I don't filter. It's a successful brown ale but not my favorite as I would like something where the yeast imparts more flavor. This grain bill with a stronger, English ale yeast strain would be good I think.
