Table Grape "Theresa"

"Theresa" is a late-ripening Hungarian table grape bred from "Eger 2" x "Olympia" with particularly large grapes. Fungus-tolerant, this variety likes sunny south / west-facing walls or slopes with minimal shade. It can be grown in rows or against a wall. Conditionally suitable as a staked freestanding plant (i.e. without a wall) and for pergola greening -- if it gets enough sun and is protected from wind. Can be grown at altitudes up to 150 m, and when trellised on a facade- up to 350 m. Due to its late ripening, damage from wasps is rarely a problem. Ideal for heavily frequented areas like house entrances.

From the 2nd or 3rd year: very large bunches, 20 - 30 cm long, loosely branched, especially beautiful ~ a 'showcase' grape ("like the ones you'll find in the supermarket"). Be careful not to keep too many bunches per vine shoot. The fruit needs a lot of initial thinning and later, moderate thinning as needed.

Yellow-green to grey-yellow; at full maturity also yellow with a touch of pink, ellipsoidal, 2 - 3 cm, tartish-sweet to very fruity and sweet; taste improves continuously during the long ripening process. Very few pips.

Late, starting in mid-September, sometimes even in November. The fruit can and should remain on the canes for a long time to reach full ripeness. Occasionally it is necessary to thin out the grapes to one bunch per cane, and do not hesitate to reduce the number of clusters to promote ripening. Make a uniform pre-harvest as soon as they are ready to eat. This ensures that the remaining grapes can ripen better and also promotes lignification of the canes.

This grape fruits better (especially in the first years) with rod pruning or cane pruning, which needs to be considered when choosing a trellis and its design. In the first years this grapevine tends to overcrop (produce too much fruit), so thinning is required. Due to the late ripening, plants may be susceptible to heat stress or "sunburn" and the associated berry wilt in early summer, especially in sudden weather changes (high temperatures / direct intense sunlight). At such times, additional watering can help. Canopy thinning around the grapes should be done (if at all) in late summer-- not all at once, but gradually in 2 - 3 stages. In late summer, some berries tend to split / burst after watering, so do not water the vines from August onwards.
