"Birstaler Muscat" is one of the varieties that we recommend for façade planting. From 15 years of experience, it is our favourite! The berry has a neutral or slightly muscat taste, as is expected with grapes, and without a disturbing "foxy" taste. The ripe grapes can be left on the vine for up to 6 weeks or longer and be eaten little by little. At the same time, their resistance to mildew is so high that no spraying is necessary. The grapes "hide" from birds and wasps. All this makes "Muscat Birstaler" one of the most valuable table grape varieties for facades!

Bare-rooted from March - May. Reserving a plant (as early as January) is recommended because of limited quantity. Available all year as a potted vine (3 litre).
"Birstaler Muscat" is a cross between the extremely high fruit-yielding "Bacchus" and the fungus-resistant "Seyval Blanc," universally suitable as a table grape and for grape juice, and especially recommended for commercial organic cultivation due to the unusually high fungus resistance (even in humid years, in regions with high humidity such as North Germany or in areas where mildew-infested vines jeopardise other nearby grapevines, such as in wine-growing regions). The high fungus resistance makes this grape also ideal for greenhouse cultivation (glass or vinyl/plastic). Flowering is also very good and reliable, making it also suitable for cultivation on wind-exposed sites. Another advantage is the fact that the grapes can hang on the vines for a long time after full ripeness... the extended "harvest window" extends the grape season! Another plus: yellow-green varieties-- unlike the blue ones -- are less visible to wasps and birds, and therefore more protected (although this is already the case with mass-plantings). Apart from that, same as per "Palatina." The grape bunch shown here (from the research garden Radebeul) comes from a plant that has *not* been thinned out-- hence the relatively small berries (only about 1.5 cm).
From the 2nd or 3rd year onward:-- medium to large size grapes, 15 - 25 cm long. Yield is usually very high, manual thinning down to 1-2 grape bunches per cane immediately after flowering is necessary for good berry size and to promote the ripening process.
Green-yellow to yellow, medium size with a diameter between 1.5 - 2cm, fruity sweet taste with a fine musk tone, very sweet and raisin-like when overripe after 6 weeks of hanging. Very few seeds.
Early, around the beginning of September. Can remain on canes for a little longer (about 4-6 weeks) and be harvested gradually.
"Birstaler Muscat" is a protected variety-- propagation is prohibited.
