Hi guys, Not really looking for a solution here, just general thoughts. I have brewed a few sweet stouts now using lactose and I never really get on with it. The brews have generally contained around 5-10% oats so this this could easily be the culprit - or the combination of the two. I always seem to have issues with carbonation and head retention when using lactose. I will either get a huge head, which dissipates quickly with little carbonation. OR average carbonation with no head at all. Whenever I do get good carbonation, its often a gusher! I don't think I have ever brewed a milk stout that has had good carbonation with a stable head. Has anyone else experienced this kind of thing? Thinking this may be a blog discussion! Happy brewing.
