This year the vineyard has picked a tonne of Sauvignon Blanc grapes from a trial plot planted four years ago. The harvest is expected to make around 1,000 bottles of wine.
Denbies, the largest privately owned vineyard in the UK, planted the Sauvignon Blanc vines in the hope that they would thrive in the UK's changing climate.
English Wine Producers marketing director Julia Trustram Eve said: "It's encouraging to see them experimenting at Denbies and it will be really interesting to see how it fares.
"The real development is the new planting of the sparkling wine varieties - Pinot Noir and Chardonnay. This is the sector that's growing the most in the UK."
