I have a bottle of OWA and a bottle of W12. They were opened on the same day. The other day I poured some OWA and noticed quite a bit of bubbles and they seemed to take quite a while to dissipate. I remember reading somewhere that the quicker the bubbles dissipate, the higher proof. Or at least that was an early test method people would use to make sure they were not getting ripped off. Anyway, I grabbed my W12 and shook it and the OWA simultaneously. The W12 bubbles dissipated nearly twice as fast. So is my memory of reading that factual and if it is does anyone have a reason to why the W12 bubbles would dissipate faster than OWA? Thanks in advance.
