"Muscat bleu" is the second of two table grape varieties that FassadenGrün recommends for walls. The grape is delicious and the resistance to fungi relatively high, so spraying is usually not necessary. Due to its dark colour, however, "Muscat bleu" is more likely to be spotted and eaten by birds than the green-yellow "Muscat Birstaler," and the harvest window is not quite as long.
("Muscat bleu" or "Blauer Muskataler," Swiss variety from "Garnier 15/6" x "Seyve-Villard 20-347")
Bare-rooted from March - May; reserving a plant (from January on) is recommended due to limited annual quantity. Available all year as a potted plant (3 litre).
"Blue Muscat" is a Swiss variety bred from "Garnier 15/6" x "Seyve-Villard 20-347" and is currently one of the most popular table grape varieties for home gardens, walls, etc.. thanks to its particularly succulent fruit. It is also grown professionally for grapes and juice. It is a grapevine for sunny southeast or west facing walls, and is highly resistant to powdery and downy mildew. It can be grown on a free-standing trellis or pergola, provided it is protected from the wind. Autumn foliage is not red but yellow!
From the 2nd or 3rd year on-- large, 15 - 20 cm long, scattered branching
Turning blue from midsummer, ellipsoid, approx. 1.5 - 2 cm, sweet with a muscat aroma, which eventually disappears if berries are left on the vine for an extended period of time after ripening. Few pips (seeds)-- approx. 1-2 pips per berry. The thick skin provides a degree of protection against wasps and usually does not affect consumption.
Early, sometimes already at the end of August
This grapevine sometimes does not produce enough buds close to the stem, which can make it difficult for beginners to prune. "Regent" is a good alternative here.
The protected status of the "Blue Muscat" variety is not yet definite. This type is sometimes used for pressing and winemaking in Switzerland.
