The Glenora Grape is the first black seedless variety. The seedless bluish black berries grow on loose, well-filled clusters. They have smooth, thin skin with sweet and spicy, highly-flavored flesh. The fruit is of a superior quality and it keeps well on the vine. Glenora has the odd trait of being a bit of a flavor-mixer. It can be foxy* and very much American in character some years and very firm, meaty and much like the European Vinifera in other years. Luckily, both ways are just delicious! It is a highly vigorous plant with medium productivity, ripening in late August or early September, about 20 days before Concord. Hardy to approximately -10F, in zones 5-8.
* Foxy: a flavor note that is wild, musky, tangy and earthy.
