Another Spearmint-wino spur of the moment brewday

[spearmint-wino]

Enjoying these last-minute brews, today's is something based on DaaB's version of Summer Lightning, lightened-up due to lack of malt and called Thunderstruck as a nod to the 2 random strikes of lightning that happened on my previous 2 brewdays, both just as the mash had gone in

Its a sign alright...

Mash well underway and holding steady around the 65.6 mark

Excellent, I'm quite partial to a bit of GFB and trying to get a stock of summer beer ready for the no-brew months.

Sparge nearly finished...

What would the efficiency be? I got 29 Litres at 1039...

[spearmint-wino]

95%

Somethings got to have gone wrong then!

[delboy]

did you temperature correct the hydro reading?

[spearmint-wino]

It read 1037 at 28°c, so I added 2 points to compensate
