Description
Neptune is a table grape for people who like the look and texture of a big green bunch grape. The clusters are large and showy, the berries are firm and oval, and the flavor is mild and fruity rather than strongly foxy.
One of its best practical traits is cracking resistance. Where late-summer rain can split thinner-skinned grapes just as they are getting good, Neptune holds together better.
It does ask for a long season. Give it full sun and a warm exposure, and let that guide placement without making it the whole story of the vine.

Additional Notes
- 🌿 Grower’s Insight: If autumn rain is part of your climate, cracking resistance is a trait you notice at harvest rather than in a catalog.
- 🌿 Regional Insight: Neptune is best in regions with a warm September and long frost-free season. In cool coastal climates, use a heat-holding exposure and pair it with an earlier grape if you want a wider, more dependable harvest window.
