flaked barley + overnight mash

[gurtpint]

Should get back to brewing come Sunday after a bit of a hiatus... Would like to do an overnight mash but I'll be using 1 kg (16%) of flaked barley. Could this spell trouble when it comes to sparging? The whole recipe can be found here: recipeview.php?recipe_id=1750

Cheers!

You could do a glucan rest first, Usually used with oats but I think I read aleman saying to do it with flaked barley as well. Mash it with 10% of its weight in pale malt at 35-40c for about 30 mins then raise the temp up to mash temp and mash with the rest of the ingredients.

I do this with oats in overnight mashes however that is a hell of a lot of flaked barley :wha: :wha:

Ta gray! Might well be doing a glucan mash then. Yes, it's a hefty amount of barley and I've been thinking about maybe decreasing it a bit. My last stout had 750g of flaked untoasted oats and it wasn't that bad. I was thinking along the lines of what I've read about the "classic"proportions of stouts - 70% pale, 20% flaked barley, 10% roast barley. Maybe scale down the fb to 800g?
