Bulldog 100 gram T90 type hop pellets, nitrogen flushed for extreme shelf life in metal layer bags for maximum oxygen barrier. The hop pellets are protected by the inert nitrogen athmosphere in the bag. This method is much better at protecting the hops in the bag, than just vacuum alone.
When you have opened the bag, you can squeeze out the air and reseal it with the “ziplock”. The left over hop pellets should then be stored in a fridge.
