So ive already done my mash mineral additions and lactic acid addition. Im now heating the sparge water. Add my second rd of minerals to the sparge water or wait to collect pbv, get it up to heat and past the hot break and then add the other minerals? I’ve always added them to the sparge water just wondered what the effect would be if any adding them to the kettle instead. It’s a neipa so I’ll be adding, gypsum, Epsom, canning salt and cal chloride and I’ve already worked out the amounts as i Use bru’n water religiously.
