I was also only referring to Spon beers in reference to their discussion on The Session. They also seemed to relate that the spontaneously fermented beers were hit and miss, with many not coming out - or one dimensional on their own. Some of the comments from the BN folks on the podcast also seemed to indicate that they really did not like the single variants they were sampling, but the blended products of Spon came together well.
They also discussed the labeling of Spon as "Methode Gueze" and the idea that they wanted honesty in process of a beer that was truly spontaneously fermented and blended from years worth of barrels, as opposed to something that is kettle soured, pitched with a known yeast and cranked out in a fairly short time.
