Now that funds are tight for affording this great hobby I'm glad that I've stocked up on supplies.
It's always a good idea to buy the 50 lb. bag of your basic base malts such as American 2-row and now I'm glad I did.
Also stocking up on the old standby hops like Cascade or Northern Brewer or E.K. Goldings when you find them at a good price is smart. They keep a long time in your freezer if kept in the oxygen barrier bags they come in.
I'm so glad that I canned starter wort too since now I have starters available for my next 6 brews. It's also practical and economical to save the yeast from the fermenter from your last brew to use in future brews. Stored correctly they can be kept viable for a couple of months.
So, now if I can come up with a good recipe for the yeast, hops and grain I have on hand, I can brew the next batch or two without ANY outlay of cash!
