Abbey yeast this time to compare ester levels. M41 too much yeast character for BPA
1 heaped tsp CaC03 in the mash and same again in sparge water
1 flat tsp CaCl in the mash and same again in sparge water
aerated 6 hrs by accident, meant to do 2 hrs
Weyermann Pilsner
Gladfield Biscuit
Weyermann Vienna
Mash slightly higher next time - 66C is a little too fermentable
Very surprised by the difference in malt flavour the CaCl has made. So much more malt flavour than I'm used to in my beers. Will have to always add... Duh.
