Can I store coffee in mylar bags or do I have to vacuum seal because it needs air like flour and sugar?
I don’t know about the Mylar bags but I use whole beans, 1/2 gal canning jars, and oxygen absorbers and works well in dark place. 2 years later and still tastes fresh
I don't know about the coffee, but I store my tea in a stainless bottle I bought them through adagio tea coupon code. They are good and easy to carry.
