It's harvest time!
A busy season when all of our hard work comes to fruition. Our team at Guillaume wishes you and your team the best of luck this harvest season.
As grapes reach full maturity (and as time permits), this is the perfect time to reflect on the season. It's essential to assess the health and quality of the grapes while considering their potential for wine production. Any virus issues in the vineyard should be addressed by rogueing and removing infected material. These findings can guide future projects, helping to make decisions about rootstock choices or adding new clones for variation and blending potential.
Dormancy preparations, which are often overlooked, should also be considered. If you have irrigation, now is the time to give the vines one last drink of water. A final spray to reduce mildew pressure before leaf senescence may also be beneficial. This practice, although new to me, is promoted to allow the vines to capture all available nutrients from the senescing leaves, storing reserves for the next season.

Guillaume's Estimated Bareroot List is now available! Reach out for the current list by emailing or calling Dylan at (530) 379-5007 or dylan@guillaumenursery.com.
At the heart of every great wine is exceptional grape quality, a topic we never stop discussing! In a recent conversation with Jean Hoefliger and Ryan Pass, we dove into the importance of yeast selection, with a key takeaway: everything comes back to the quality of the grapes.
