Brewed my APA today, Bairds Pearl with global light and pale crystal to 8% combined. Pacific Jade to bitter and Simcoe & Amarillo at 15/10/0 and dry hop later on. A gain in efficiency today of about 5%. BIAB but with a sparge step, increased the time the sparge water sat on the grains for the last two brews and it's paying off. Up from 66% to 72%. I'd love to be able to get a consistent flame to get really accurate with gravity and volume. It's the one variable I don't have much control over, hopefully I'll have a garage one day to avoid the wind playing a part!
I find stacking some old bricks about half way around the burner on the side the wind is blowing shields the flame and gives a more consistent boil off. While the wind blowing over the top of the kettle will increase boil-off I find that it's a negligible amount.
Yeah I've got some bricks set up and also a few bits and pieces lying around to try and create some cover. Today was southerly so I'm quite covered and didn't suffer from too much wind and ended up being able to turn off 1 of my rings. However because of this constant change I just can't seem to nail my boil off rate.
I think today's was a lowly 11%, is that getting a bit too low? At some points my boil just looked way too ferocious so I backed off the gas.

OG 1.061 was a little high but we'll see how it goes.
Cheeky Bloody neighbour popped her head in the pot and said "That doesn't smell like beer, it looks like pumpkin soup."
She nearly bought it.
