Grgich Hills Estate Flyways, Wildways and Waterways Field Day

150 S Kelly Rd
American Canyon, CA 94503

Registration is now closed, but if you want to attend, please contact Shelly at [email protected] or 828-406-9484.

Join WFA for an interactive field day at the Grgich Hills Estate American Canyon Vineyard, the largest of their five vineyards.

Grgich Hills Estate Winery celebrates the role biodiversity plays in growing wine grapes. Rather than eradicate all pests, they seek to keep them in check with the use of Barn Owl and songbird boxes. They also keep the ground covered in between vine rows, mow cover crops rather than tilling, and leave roots other than vines for pest voles to eat.
