I vacuum seal the whole pound in a large bag with a lot of extra space. When I need hops I cut open the top, take out what I need, then reseal the bag. One of the reasons why I like bulk hops is that I brew smaller batches and don't often use even numbers of ounces in a recipe. If my hop bill is 1.6 ounces of one hop, 3.5 of another and 2.25 of a third I don't need to worry about wasting hops. If I broke everything down into smaller bags I would.
