The one on the left is my first batch, the right my second (just bottled).

I'm very happy with the colour improvement and the sample tastes were better too. Fingers crossed I'll have a much less bitter batch.

My changes to the first run were blocking any outdoor lights (newspaper over window -my wife loved it) and keeping it in a water bath to regulate temperature until sampling time.

In the next batch, or the one after, I should have an under counter fridge to keep it in so this'll help even more.
