A Reminder about Transferring High-Proof Ethanol
I got a note today from David E. Block and Konrad V. Miller at UC Davis regarding the operational dangers of high-proof ethanol. I’m sure that this is all very familiar information to any distillers as well as winemakers making fortified wines. All the same, I’m going to post the note in it’s entirety just in case anyone in the wine industry that doesn’t have experience handling high-proof ethanol is now doing so. High-proof (e.g. 70%) ethanol can be an effective sanitizing agent against the coronavirus causing COVID-19. Spraying of small winery surfaces or equipment for sanitization with this solution is not problematic, especially in a well-ventilated area. However, pumping high proof ethanol (for the purpose of creating sanitizing solution or sanitizing large pieces of equipment) using a normal winery pump could be hugely dangerous (explosion hazard) and should be avoided. While winery and distillery pumps are extremely similar, there are critical operational a...
