**Brewday Notes:** \\

Pitched onto yeast cake from Vetemjölk (after 5 months in primary). \\
Strike hit perfect, 65C. \\
7.5L extracted in mash out. \\
Teabag sparged in 4.5L, got a lot more sugar, brought up to 11L. \\
OG: 1.050 \\
Bubbling in the morning (8 hours later). \\
\\
Bottled over a fucking year later: 2016-11-13! \\
Small pellicle on top looks like it might be lactobacillus, but what do I know? \\
FG just a touch under expected: 1.008 (5.5% ABV) \\
Primed with 150g table sugar, aiming for a high 2.6-2.7 volumes CO2 \\
No idea if the yeast is still alive, and don't have any to re-pitch. \\
