Like many homebrewers I only grazed the info of what other posters were talking about and pieced it together to create my kind of story. A lot of “sour soleras” for homebrewers means whipping up a massive 30-60 gallon batch, letting it age in a barrel, then at X number of months/years pull 5-15 gallons and replace with new. Headspace fills back in, you’ve got aged beer and fresh beer, it’s in a neat in a little package, and so it goes. To me this sounds like someone took the idea of what Rodenbach does with bottling for their Grand Cru and ran with it. Only, this isn’t really what on is, this a solera is:
Quick details: Brew 8 gallons of ‘house’ every other month for a year (solera -> 5). Bottle 4 gallons (solera), blend 2 gallons from each fermentor down newest (6) added to stack while birthing a 4 gallon one-off.
First thing one would likely notice is the painful vertical nature of my solera. I toyed with a building a ‘base’ solera first to then move build up and attempt to blend down, but this is simply a starter project. It’s really a peek into how much I’ll hate brewing the same thing over and over, how much I’d enjoy working a brewery, and an exercise in patience. I may end up not loving the idea after a year and a half and just bottle the thing and give up. It’s a working example.
