I brewed miunchen wheat beer and bottled one week ago. I used carb drops to each bottle for carbonisation. I checked bottles yesterday, all bottles have few mm white yeast cake on the bottom and it seems all of them also have white film on top. I put one bottle into fridge and tasted it few hours later, carbonation and head was still too weak, there were no strange smell, white film more or less was gone, but there were some of it in a glass, maybe some yeast got into glass. Taste was not sour, almost normal maybe just need more conditioning time, but there were some very little slick or viscous mouthfeel. Does it look like lacto/pedio infection? Should I throw it away?
