How Grape Ripening Follows Growing Degree Days and
Managing Vineyards for High Quality,
With Luke Haggerty, Cornell University and John Thull, University of Minnesota
Tuesday, December 10, 2013
11:00 am Central and 6:00 pm Central
Join Luke Haggerty and John Thull for a two-part webinar. Luke, who was recently hired as the Viticulture Extension Specialist for the Lake Erie Regional Grape Program, will discuss the MS Thesis work he completed at the University of Minnesota. Over three seasons, he tracked fruit chemistry changes during ripening to determine if GDD could be used to predict grape berry maturity.
John Thull is the vineyard manager at the University of Minnesota Horticultural Research Center and owns a four acre vineyard. In these roles, he has gained a lot of experience in managing cold hardy grapevines to product top quality fruit. John will share the strategies he uses to achieve high quality year in and year out.
Register for the webinar at the link below. Registration will be open through 8 am (Eastern) on Monday, December 9th.
Participants will receive an email the MONDAY before the webinar containing the web address (URL) for both webinar sessions as well as connection instructions.
Registering for one Northern Grapes Webinar will place you on the mailing list, and you will receive announcements and connection instruction for all further Northern Grapes Webinars.
