Bottling done - and out of the fermenter this is tasting stunning.

I've given the polypin another go... it will be disappointing if this is 5L wasted. I think the mistake last time was releasing pressure in the polypin too quickly/frequently- so I think I was pushing oxygen back into the beer each time. The plan this time is to try wait a week before doing anything with the polypin. Leaving it later should give enough co2 build up to make sure the oxygen is purged.
