Humidity and Additives

[Ignoble Grape]

Hi All -

Moved from a relatively dry climate to one with more humidity. Went to add my pectic enzyme to a fresh batch of strawberry wine and it was caked into the bottle. For salt, I add rice grains.... How do you keep your powders fresh if you live in a humid climate?

Thanks!
Erin

Yep, refrigerate. Both heat and humidity are issues. Or could vacuum seal the non-volatiles.
