Growth and leaves. Growth is strong to vigorous and the vines are highly adaptable. The leaves are medium-sized, dark green, glossy, five-lobed and moderately incised – one of the variety's distinctive identifying features.

Flowers and fruiting. The flowers are hermaphrodite, so the variety is self-fertile and needs no pollinator. Each shoot usually carries two inflorescences and fruiting buds form every year. Cane ripening is consistent even in unfavourable seasons, and cuttings root very readily.

Clusters. Large to very large, averaging 500–600 g, with the biggest reaching 1.5 to 2 kg and more. They are conical, often branched, medium-dense to loose, and command a high market value.

Berries. Medium-sized to large, weighing 4–6 g and measuring roughly 20 × 18 mm, slightly oval. The colour is creamy yellow to amber with a fine waxy bloom. Around a third of the berries in a cluster tend to be seedless.

Flavour. The flesh is crisp and very juicy, the taste harmonious and sweet with a well-balanced sugar-to-acid ratio. In tasting trials of fresh grapes it scores up to 8.8 points out of 10. Sugar content reaches 19–22% at an acidity of 3–5 g/l.

The marker is plotted on a 0–25% sugar scale and shows the midpoint of the stated range (20.5%).

Ripening. An extra-early variety with a growing period of only 100–118 days at an active temperature sum of 2000–2200 °C. Depending on the region it ripens from the second half of July to early or mid-August. A major advantage is that the berries ripen satisfactorily even in climatically poor years.

Pruning and bud load. Medium pruning to 5–6 buds or long pruning to 8–10 buds is recommended. The optimum load per vine is 35–45 buds.

Yield. Very high and stable, averaging 8–10 kg per vine and reaching up to 25 kg under top care. The variety has a strong tendency to overcrop, so leave one cluster – two at most – per shoot and remove crowding lateral shoots.

Site and lifespan. It needs the warmest, best-lit spot in the garden, for example against a south-facing house or fence wall, and does not tolerate excessive moisture. A healthy vine given proper care crops well for 15–20 years.

Growth. Strong and vigorous, which makes the variety ideal for covering pergolas, garden shelters, fences and walls.

Clusters and berries. The clusters are medium to large at 350–500 g and, importantly, loose – the berries do not deform one another and no laborious thinning is required. The berries measure roughly 2 cm across and are dark reddish-brown.

Ripening and yield. A mid-late variety that ripens in mid-September under Latvian conditions. Productivity is high: on his 1.8-hectare vineyard Sukatnieks himself produced up to 8 tonnes of grapes a year alongside 20 to 26 tonnes of apples.

Hardiness. It withstands frosts down to −30 °C, with some sources citing −35 °C. It needs no winter covering; in the harshest years it is enough to lay the canes down in autumn and cover them lightly with conifer branches. The variety is also noted for its overall vigour and good health.

Vine and pollination. Growth is moderately strong, so the variety is easier to keep in check in smaller spaces. It is self-fertile and will crop even as a single planted vine.

Clusters and flavour. The clusters are medium-sized, averaging 120–150 g. The berries are green, sweet and carry a very pleasant honey aroma.

Storage life. The variety's greatest asset. If the clusters are harvested in autumn before the first frosts arrive, they keep successfully in a cool cellar until January.

Risk. The fruit ripens on the vine only in October. In cooler years or in more northern sites there is a risk that it will not ripen fully before the heavy autumn frosts. The smaller clusters are the price paid for the late harvest date.

Vine and leaves. Growth is moderately strong to strong. The leaves are small to medium-sized and three-lobed, with the central lobe longer than the side lobes and a half-open petiole sinus. The variety is self-fertile.

Clusters. Medium-sized, 10–12 cm long and weighing 150–180 g, cylindrical-conical and elongated like an ear of maize. They are medium-dense to dense, some with a single wing; the cluster stem is short and green with reddish stripes.

Berries. Medium-sized and round, weighing 2–3 g, yellow-green with light bronzing on the sunny side. The skin is thicker and firm, so the berries do not crack. The flesh is fleshy, juicy and slightly gelatinous – a typical trait of varieties with Vitis labrusca in their background – and contains two to four small seeds.

Flavour. Very good and sweet, with the typical labrusca character and pronounced muscat notes. Sugar content reaches 18% at an acidity of 5–7 g/l.

Harvest and use. It ripens in the second to third decade of September. It is excellent as a dessert grape, but also for quality juice and for a highly aromatic wine with floral, muscat and exotic-fruit notes that is best drunk young.

Growth. Strong and vigorous, which makes the variety suitable for covering pergolas, garden shelters, fences and building walls. It is self-fertile, so a single planted vine will crop.

Berries. Relatively large by northern-variety standards, slightly oval and green-yellow. The skin is thin, a considerable advantage for fresh eating compared with many other frost-hardy varieties. The flavour is sweet and very pleasant.

Ripening. A mid-late to late variety; under Baltic conditions it usually ripens from mid to late September. In a cold, rainy autumn the date can shift to early October.

Hardiness. Very good, with the variety withstanding frosts down to −25 °C. In sheltered positions, for instance against a south-facing wall, it usually needs no elaborate winter covering.
