See it on our grape and kiwi disease chart (opens in a new tab)At a glance: Somerset Seedless Grape is a grape vine rated hardy to zone 3 in our ratings (winters to -40°F), and self-fertile, so one plant can crop.
| Hardy to | Zone 3 to 8. A bare number means the whole of zone 3, colder half included (winters to -40°F). Find your zone with our cold hardiness calculator. |
|---|---|
| Chill hours | About 500 hours (350 to 750). Our estimate. No published figure exists for this variety yet. Montana winters give it plenty. In milder climates, make sure your winters average at least this much. Check your chill hours or see our sources. |
| Pollination | Self-Fertile. Bloom group 4 of 7 (mid), late spring to early summer here. Somerset Seedless has perfect flowers and sets fruit on its own, so one variety is enough. Seedless grapes still need their flowers pollinated, but Somerset does that itself. Grapes bloom in June, well after tree fruit. Bloom group is our estimate from the variety's origin and relatives.

Somerset is arguably one of the most cold-hardy seedless grapes. It produces rosy, small to medium-sized compact clusters with medium-sized berries that have adherent skins and a strawberry-like flavor.
Best Uses
Best known for fresh eating, Somerset also holds potential for use as a sweet red dessert wine. It could also be used for jams and juices. Its versatility and great flavor make it an excellent addition to your edible landscape.
Cold-Hardy Performance
Somerset does well all over Montana, with the exception of the coldest microclimates east of the Continental Divide, where temperatures can dip below -40°F. For example, we spoke to a customer in Joplin, Montana, who claimed the ambient temperature Jan. 2024 hit below -65°F (though we still need to verify this). Even if it reached -55°F, Somerset may struggle in such extreme conditions.
Protecting Somerset in Extremely Cold Climates
In these colder climates, consider training the vine’s arms (cordons) low to the ground and mulching over them in the fall for added protection. This technique can help guard against severe frost. Hardy to -40°F, Somerset is a resilient variety, but a little extra care may be needed in extreme conditions.
Plant Size
These are vines going on their second year with an established root system.
