I just bottled a batch of Irish Red Ale and have some white stuff floating in the top of each bottle - looked in on them after a week. In the late 80's I moved to a house and got a crud in the top of every bottle (that affected the taste of the beer) even though I am (and was) fanatical about sterilization. I assumed it had to be something either in the water or air there and quit brewing for many years because of it. Now this is my 10th batch this year and don't know of anything I did different. Any suggestions? Thanks - Jimmy
