Having watered the relatives with light coloured ales over christmas, and brewed a keeping IPA for Easter, I thought it time to return to my fave, copper coloured best bitters. This was the first time I've brewed this recipe with an adjusted alkalinity and mineral additions. The brewday was Sunday, and all went well, no problem chilling it post boil
