So my old timey Boddington's beer-a-like is going into casks today and the people who drink this demand clarity, it's one of the characteristics that Boddngton's was always judged on. Personally, I can't abide isinglass - it's a foul product - but needs must sometimes. My question is should it behave like this? I put some in a glass to see what happens and am surprised to see it coagulate at the top, i thought it would drop through. My worry is that I dispense from the top rather than the bottom in casks.
