NYWGF visits the Chautauqua Region

The New York Wine & Grape Foundation, led by Executive Director Sam Filler, is thrilled to announce their upcoming visit to your region this April!

During this visit, NWYGF will host an information session about programs affecting our industry. As you may know, NYWGF is sponsoring a Vineyard Survey aimed at gathering accurate and insightful data about grape growing in New York. If you are a grape grower or wine maker in the state, your input is crucial in shaping the future of funding and promotion for the industry. By participating in the survey, you will be contributing valuable data that will help inform decisions about the industry's future growth. We invite you to learn more about the Vineyard Survey, how you can help by providing your data, and how the results will be shared and will support the industry.

The NYWGF team will also be sharing information about our valuable membership benefits and services, as well as giving you an overview of the New York Sustainable Winegrowing Program. The New York Sustainable Winegrowing Program provides a clear pathway for vineyards to achieve certification by implementing regionally defined sustainability standards.

To make the visit even more valuable, a free lunch will be provided.

This is an amazing opportunity to learn more about the exciting developments happening in New York's wine and grape industry. NYWGF is thankful to our partner, American National Insurance, for making this visit possible. This public-private partnership showcases the impact that we can have when we work together towards a common goal.
