So I am going to have a $500 windfall that I want to put into my brewing setup. I eventually want to go to 10G batches. How would that money be best spent. Currently doing AG with the typical turkey fryer burner/alum pot/cooler setup.
Could not agree more, while you're at it consider gear for making starters, (stir plate and bar, flask etc) and maybe an aeration kit.If you don't already have a temperature control fermentation setup, I'd put your money in that and then the rest into your brewing system.
Begin saving money to reinvest in your brewery.Yeast starters are a great (and easy) way to make better beer. Get yourself a stir plate and flask. You'll still have plenty of $$$ left over for any other single upgrade.
