AJ, to verify I have a correct understanding of the baseline water treatment, I should make the following additions to 100% use of RO or DI water for the following BIAB recipe.
Grist
8 lb 2 row
8 oz caramel 10
7.75 gal mash water-no sparge
ADD:
7.7 gm calcium chloride (1 gr per gal of water)
2.7 oz sauermalz (2% of 136 oz grist)
Optional addition to baseline of 6 gr of gypsum (.8 gr per gal) for a pale ale.
Yes but suggest you work up to the gypsum. You might also want to start with 1/2 g/gal on the calcium chloride IOW work up to that too.
Also, should I avoid any sauermalz addition for a recipe like the following due to the amount of roasted malt in the recipe?
GRIST
8 lb 2 row
8 oz chocolate malt
8 oz roasted barley (Briess)
8 oz C-60
Yes, in general if you have 10 - 20% high colored grains you can get away without any acid or alkali.
