Jupiter grape
variety of grape
The Jupiter grape is an interspecific seedless Muscat grape developed at the University of Arkansas in 1998. It is a cross of Arkansas 1258 x Arkansas 1762, both of them V. labrusca and V. vinifera hybrids. The Muscat flavor comes from “Gold” (vitis vinifera) variety; the seedlessness comes from “Reliance” (vitis labrusca) variety.
This 1998 grape variety patent by the University of Arkansas lapsed in 2019..
Jupiter has large, oval blue-purple berries on large clusters. Its skins are not too tough or too tart to impede its desirability as a table grape. It has mild but pleasant flavor and a pronounced flowery "Muscat-type" aromatic profile that carries through in wines made from it. It can be trained to an upright growth habit. The grape has moderate-to-strong resistance to fungal diseases, and can be grown successfully in climates as different as the South and the Pacific Northwest. The variety can attain 21 Brix in sugars and has reached high yields of 25-29 tons per acre.

Why this record matters
“Jupiter grape” is worth following because a concise public description often conceals a longer documentary argument. Here, Jupiter, grape and variety provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 16, 2026. The linked authority identifier is Q16253072. The first chronological checks are 1998, 1258, 1762 and 2019.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
