slightly off topic, but the OP and I are making near identical batches concurrently and I'm curious.
and thank you for sharing your BOS Lambic recipe and notes AK.
Yes. The reason Rodenbach (IMO) is so dang good is the complex intermingling of acetic and lactic sourness with the oak/fruit/malt flavors. Based on this source
, I would say it is in their wood. I get it from bottle dregs since Roeselare doesn't have it. I don't necessarily want it, but it's in some of my favorite beers, so it goes in. I just have to be mindful of any oxygen sources during aging/transferring/bottling.
I would not , however, use vinegar itself to get an acetic character. That would be like souring with straight 88% lactic acid. Yes, it will be sour, but it will be boring. (Mike over at the Mad Fermentationist did a 'quick sour' experiment with lactic acid and Brett, I believe...)
OT, but you're quite welcome! I hope to post the results of the blending I did once my score sheets come back from the UMMO and another comp.
