Although the recipe in the BrewDog book was apparently shared by Beavertown. The numbers don't add up. Book saying 45 IBU, calculator saying 18 IBU and Beavertown website saying 55 IBU 🤔
Currently The Malt Miller do two sizes.
15ml £2.50 = approx 2 doses per 23lt batch.
250gram £8.99= approx 35 doses per 23lt batch.
I probably won't get through the larger pack before the expiry date. It's a shame they don't do something in between.
I love Gadd's dog bolter, I remember back in the 90s you could get a Bruce's dog bolter extract kit.
I spoke too a brewer from Gadd's at a promotion at my local garden centre, he said he'd worked at Bruce's back in the day and it was the same recipe.
I've used the flow stopper in both my methods of transfer.
If you're using the spunding valve method, you just need to fit the spunding valve after the flow stopper and get it reasonably close to vertical.
