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.
