Hey guys, sorry if this has been discussed before, but I haven't seen this specific question answered yet...
I have a starter that I've been building up by using bottle dregs from various sours and adding fresh starter wort. It's about 1/2 gallon now and I plan on building it one more time to a full gallon and adding a few more bottle dregs. My plan is to do a complete fermentation with just the cultivated dregs. (no primary sacc yeast)
My question is, should I be aerating this starter? I tried to keep oxygen out as much as possible, even purging the growler with some CO2 before adding the starter wort and its still very active. I know that oxygen is not good for certain organisms like pedio, but good for others. And what about when I pitch this starter to the beer? Should I aerate like usual, or not at all? I really don't want a lot of acetic acid in this beer. I would like a more gentle, lambic like sourness. I plan on aging this for at least a year or two.
Any suggestions from experienced wild brewers would be appreciated. Thanks!
