AMES, Iowa – Winemakers can improve their chemistry skills through a series of virtual workshops offered by specialists with Iowa State University Extension and Outreach.

Four workshops will be presented live via Webex, beginning April 3 and concluding May 1. Each workshop will include a background presentation, live demonstration of laboratory techniques, a hands-on practice, guidance through calculations and group discussion.

“This is the first time for us to offer a live ‘virtual’ workshop on wine chemistry,” said Watrelot. “The topic is important to winemakers and those interested in making wine, and the format will allow them to complete the same practices as the speaker.”

Watrelot said participants will need to have some basic equipment to complete the tasks involved. Some supplies will be shipped to participants in advance.

The goal of the workshops is to provide knowledge and tools that can be used in Iowa wineries and beyond.

Presenters will include Watrelot, in addition to Alex Gapinski, a wine scientist who holds a master’s in food science and technology from Iowa State University.

Each webinar will last from 10-11:30 a.m. Participants can register for as many webinars as they would like, and should register by March 20 to help with planning.
