Overview
Valiant is easily the most cold-hardy grape available, having survived -50°F winter temperatures and still produced a crop the following year.
Flavor and Uses
Valiant grapes are blue in color and have a taste similar to Concord. These grapes can be enjoyed fresh or used for jams and juices. While some have tried them for wine, the results have been mixed, so they may not be the best choice for winemaking.
Cold-Hardy Performance
Hardy to zone 2, Valiant is a reliable choice for gardeners in extremely cold climates. Its resilience in harsh winters makes it a top pick for colder regions. Valiant has survived in some of the coldest parts of Eastern Montana, and has still borne a crop there, where temps reached near -50F.
Plant Size
These are vines going on their second year with an established root system.
Questions we get about Valiant Grape
Does Valiant Grape need a pollenizer?
No. Valiant Grape is self-fertile, so a single tree can set fruit. Valiant has perfect flowers and needs no pollenizer. Grapes bloom in June, well after tree fruit.
How cold hardy is Valiant Grape?
We rate Valiant Grape hardy to zone 2, which means winters down to about -50°F. Our ratings come from real winters at our two Montana sites and from trusted growers across the North, not from a catalog average.
How many chill hours does Valiant Grape need?
About 500 hours of winter chill (we count hours at or below 45°F), likely somewhere between 300 and 800. Nobody has published a chill figure for it, so that's our estimate from its relatives and origin. Valiant's chill need is met easily in Montana. Late frost after budbreak is a bigger risk than too little chill. Our chill hours guide has a calculator for your winters, and our research page lists the sources.

Is Valiant Grape disease resistant?
Not really. It holds up moderately well against powdery mildew. It's very prone to downy mildew, and prone to black rot, botrytis bunch rot and crown gall. Nobody has published solid data on it for anthracnose and Phomopsis cane spot yet, so we list those as unknown. Our grape and kiwi disease resistance chart has every rating, the notes and the sources.
Will deer eat Valiant Grape?
