blending sours

I made myself a one gallon sour that is 9 months old now. Tastes pretty stellar. If i threw this one gallon into a keg and carbed it and let it sit could I then blend with it another one or two gallon sours in a few months?

Or should i just rack it to the keg and purge oxygen and just let it wait?

The idea is that i would like to be able to drink it while it sits and just kind of have an ever evolving sour. I adding stale beer to carbed beer is no good then I'll avoid it though.

nice a keg solera. should work well given the gallon actually lasts til the blend

Oh yeah, I can make this first gallon last plenty of time. I am pretty good at hiding beer away and forgetting about it. I can have two or three more gallons going in a couple weeks. Then blend in 6-9 months.

Any other sour batches will just wait till there is space in that keg...if it ever gets full. And i just have to make sure it never runs dry, which will be simple given the premise of the whole thing.

So mixing carbed and uncarbed is ok?

As long as you can avoid oxidizing the beer during the transfers.

Yeah i can do that.

I just researched the term solera, had no clue this technique existed. It's pretty much exactly what I am going for, except I will be drinking from the holding vessel and filling it whenever I feel like it, vs just a holding tank that I take a set amount from every year.

This will be fun, and as long as nobody drinks all of it one night I will be fine lol
