More and more I find myself in the need of a little Starsan to sanitize equipment in between brews. To sanitize a pipet to do a gravity read, to sanitize raking equipment, etc.
I’ve been thinking about making a decent amount and then storing it in 1 Gal water jars. Does anyone know how long it will stay “good” or keep it’s sanitizing power? Is making a batch and then storing it a good approach or should I figure out a way to make small amounts “fresh” every time? The way I’ve been making it at brew day is to add an amount to 2 gal in a brew bucket and that works great but I’d love to hear how you do it.
