The isopropyl alcohol blew off after a few minutes just as you described, but the fellow broke out another bottle from his library just for the insult of the thing.
Hmmm....that's interesting about the use of isopropyl as a commercial winery sanitizer. Especially when there are good inexpensive food-grade, no-rinse sanitizers availible these days (Star San, idophor, potassium metabisulphite, sodium metabisulfite, One Step, etc.) Does anyone now if the use of isopropyl as a sanitizer is a common practice in commercial wineries?
