If hops are fully dried and vacuum sealed
do they need to be frozen?
Thanks
Yes
Lower temperatures reduce the effects of aging. Here’s a calculator that you can play around with to see the effect of temperature.
Absolutely should be kept frozen for as much as their life, as possible. When stored in metalized mylar packaging, I’ve had hops last for many years with little or no degradation in flavor, aroma, or bittering. I’ve investigated those bittering loss formulas, but they seem to predict much more loss than I perceive when I brew with them. That must have something to do with keeping them frozen.
Yep. Keeping them frozen and vacuum packed makes all the difference.
