Colossal Cabernet trial under the California sun Ahmad Hakim May 08, 2020
A huge Cabernet trial is underway in California, encompassing 100 clone/rootstock combinations and covering 3.5 acres. Researchers designed it to help identify genetic variations that impart a greater resilience to climate change — notably, improved drought tolerance that will enable more effective and sustainable water-use practices while also producing high-quality fruit and wine. 

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

Student Profile: DEVO president Hannah Hanlon Andrea Thompson January 21, 2020

Undergraduate Hannah Hanlon grew up in rural Minnesota, complaining about working for her parents as many children do. When she was ten years old, her parents opened a small family-run winery. Working summers in the vineyard and tasting room, and winters in the winery, she was determined to get out of the country and out of farming.
