  Neat, that's very interesting as it does mention it's present in the ferment.

  There's also the possibility of forming an azeotrope (like with ethanol/water at 96% ethanol). Azeotropes are cool, they're exploited a lot e.g. as working fluids in heat pumps.

    Interactions between ethanol, water and guaiacol are a key concept in the article. So there could be an azeotrope, I suppose. There's one for anisole aka methoxybenzene. Its BP is 153.8°C, and the anisole-water azeotrope (40.5% by weight) boils at 95.5°C.[0] Guaiacol is 2-hydroxyanisole, so maybe there's one for it too. 0) Horsley (1947) Table of Azeotropes and Nonazeotropes http://sci-hub.io/10.1021/ac60008a002 http://sci-hub.io/10.1021/ac60008a002
