I’ve just put away approximately 15 litres via gravity transfer to a purged 19 litre Corny keg, which also received half a crushed Campden tablet. The keg was placed on CO2 at 20 PSI. No time to measure gravity – got my hands full with an unexpected boiler leak in the utility room.
One final observation was that the Krausen trace inside the fermenter was a good six inches tall, which I’ve never seen before. Good job there weren’t 20 litres in there, would have made one helluva mess of the fermentation chamber!
