Stout!

[drjim]

So I've assembled a new brewing area, or rather built a tiled worktop next to the shed. Cleaned out the mash tun and the bizarre green copper gunge in my big kettle caused by leaving copper cooler in what may have been chemsan - abundant verdigris if you forget about it and go on holiday for a couple of weeks and are then ill for a week or so after!

Did a quick bag brew in my 40L buffalo boiler. Wood fired joy tomorrow all being well.

So in honour of my late Father I made a batch of Grandad stout.

Too much malt for it to work properly as BIAB, volume numbers don't work at all, so I dropped the bag into a spare fermenter and sparged 5L through it. Topped up the kettle at the start of the boil.

OG came out at 1058, was expecting 1052, this is export strength stout!

It's now sat in my shiny klarstein conical, got 30L so it's full almost to the top. Cooled down to 22 degrees using water from the swimming pool which needs draining anyway. Going to ferment cool by leaving it in the shed, ambient temps round here will be below 20 for the next week or so, hopefully it will ferment itself slowly without bursting out of the airlock and there will be a nice stout at the end.

We shall see!

I’d love to try a bottle of that, but what is XML Ale yeast?

Crossmyloof, just how I abbreviated it in my inventory in brewfather.
