I purchased 5 lbs of bulk hops that I plan to store in mason jars with a vacuum sealed lid. I was just wondering, is there any thing I should be concerned about when I use them for dry hopping? I have been used to using vacuum sealed pouches, which I sanitize before I open, but I am not going to be able to do that once they are in jars. Whats the best way to deal with the hops? I figured I would clean/sanitize the jars, and then put in the hops.... but, I am a bit worried about when I take them out and measure the weight for the dry hop additions. Am I being overly paranoid about the hops getting some bugs on them before they go into the beer?
