I am fermenting a batch of double IPA, and the instructions say to sprinkle the 2 additional ounces of hops over the top of the krausen. They assume that it is in a bucket, but mine is in a 6 gallon carboy. How am I supposed to sprinkle through a 2" hole and get it to spread and cover the top of the krausen? Is there another method or should I ferment initially in my bucket for this style of beer in the future?
