I'm sure this question has been beaten to death but I'm going to ask it anyway. I just picked up an 8oz. bag of Mylar sealed Penzance from one of our Canadian brothers. I normally pop the seal on everything I get and pack it down into wide mouth four or eight oz. canning jars. But, it's the middle of winter here and the few jars I can find are of the narrow mouth variety.
I'm a glass half empty guy so please bear with me.
Will this well sealed pouch be okay until the earth rewarms, daffodils spring up and the Dogwoods start blooming? At that time, Wal-Mart, Lowe's, Home Depot and our new Menard's will be restocking their canning supplies and I'll be able to purchase the jars I prefer.
I'm also just as interested in preserving recently 8oz. purchases of well sealed P&C's Larry's Blend and 10 to Midnight.
