Hi Gang, I've been drinking a dunklewiezen i made for a few weeks now. After 2 weeks in the bottles I've had to be very careful about opening the bottles. If I open normally - quickly - I get a volcano and the yeast cake breaks up and dissolves into the beer ruining the nice flavors. I carbed it to about 3 volumes. When I open it slowly and gently and pour it fairly quick the yeast stays in tact until i get most of the beer into a glass but it still catches me out now and again, It also has made the beer almost impossible to share with people as they haven't got the knack of opening them. Anyone else encountered this? Anything I could have done that is causing it? The yeast I used was Mangrove Jacks M20. I've another regular Bavarian wiezen to do this weekend, my recipe says 3-3.5 vols. I really don't want it ruined by loose yeast, I think its going to be a good one! Thanks!!
