Safe Transfer of High-Proof Ethanol Using Pumps

March 27, 2020

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

Climate change is coming for your wine. What the world's wineries are doing to save grapes Ahmad Hakim September 09, 2019
Soaring temperatures, irregular rain patterns and the ever-present threat of fires is causing winery owners here and around the world to adopt aggressive strategies to safeguard their livelihoods. These tactics include experimenting with new varieties of grapes, finding new ways to maximize water use and even seeking out land in areas that formerly were too cold for vineyards.
New System More Accurately Estimates Vineyard Crop Yields Ahmad Hakim August 06, 2019
A company is developing a computer vision system to estimate vineyard crop yield with the collaboration of UC Davis scientists. On Friday, Nathan Strong, president and chief executive officer at Terroir AI in Menlo Park, demonstrated the system at UC Davis’ Oakville Station. Strong installed a box containing four sensor cameras in the back of the station’s ATV, the cameras adjusted for the high-wire trellis system of the experimental block.
