Just put away almost a full 19 litre Corny keg plus around half a 5 litre MJ Mini using traditional gravity fed method, no purging since we’re not overly hoppy. It’s in the kegerator now on pure CO2 at about 15 PSI.

Checked in on my imperial stout just now, and maybe I should have fitted a blow-off tube right from the start, because it seems we’ve had something of an explosion. I’m not sure what caused the airlock to separate into two halves and explode toward the top of my fermentation fridge, but I was half expecting to find a dent in the ceiling.

Replacing the stricken part with a taller type of airlock caused that one to fill up immediately as well, so I did what I should have done yesterday and fit a blow-off tube filled with sanitiser. Let’s hope this one doesn’t erupt.

#wisdom: Air-locks are for beginners, just use a blow-off tube from the start.

* the original brew day was delayed 24 hours by a ‘gastric episode’ which may or may not have been related to rare duck.

Fairly standard brew day today but with disappointing results, probably due to the thickness of the mash. To be honest I’m still not sure whether to manually correct my hydrometer readings before plugging them into Brewfather, or if it’s smart enough to know that a pre-boil reading following mash-out at 75℃ needs to be corrected for 75℃, and doesn’t expect the user to leave the batch screen, head over to the tools screen, do the correction, then plug the values back into the batch screen. On a previous batch (Hornindal Pale) I worked out that the efficiency is the same and just the actuals vary, but on this one I’m unsure. Anyway, these things are probably best pondered over with a fresh head, and not after a long brew day. A couple of images and raw notes to follow.

Usual approach for Yeti; 184g DME, 1.5 litres water, a dollop of Lipohop, pinch of yeast nutrient. The original brew day was scheduled for next day which would have been a bit tight in terms of growing this starter, but a short-lived tummy bug intervened and I’m now brewing two days after building the starter. Looking at the foam atop my Erlenmeyer flask I’d say this is a sweet spot anyway, so I’m hoping for it to take off not long after pitching.
