Two words: mason jars!
If you have the space in your freezer, these are the way to go for pellet hops. I split up 8lbs from a group buy and it was a snap. FYI one pound of pellets fit perfectly in a one quart wide mouth mason jar!
Use the foodsaver to vacuum seal one jar; when you need hops, break the seal, weigh out what you need, put the lid back on, run the foodsaver again, put hops back in freezer!
