I brewed my first batch using hops in a muslin sack and it wasn't until I was into it that I realized that I didn't know how to use them for sure. I cut off a portion and then added 1.5 oz of hops like I planned. I tied a knot in both ends and trimmed off the excess. It was then I realized that I had packed the sack fairly tight. How tightly packed should I make a sack when using it? Does it matter? Does anyone have a picture of what a properly prepared muslin sack looks like that they would be willing to post here?
