- Vine variety information
Freisamer (originally known as Fr.21-5)
Mother: Silvaner
Father: Ruländer (Pinot Gris, Grauburgunder)
Year of breeding: 1916, by Professor Karl Müller at the Staatlichen Weinbauinstitut in
Freiburg. Initially it was named Freiburger but in 1958 the name was changed to Freisamer.
Country of origin: Germany
History: it was introduced as a major improvement on the then poor yielding Ruländer (Pinot gris).
Breeder/License holder: Staatlichen Weinbauinstitut in Freiburg
Number of clones: Fr.130 and Fr.131 (slightly higher yield and slightly lower acidity)
Year of entry into the German Federal Office's Varieties Register:
Area planted in Germany (July 2006): 14 hectares (only 12 ha in 2001).
Presently it is grown in Baden-Württemberg (9 ha), Rheinpfalz (3 ha) and the Nahe (2 ha);
also in some Swiss cantons (3.86 ha in 2005).
Area planted in England (as at August 2004):
Wine Character - colour:
- bouquet: neutral
- palate: neutral, fine, harmonious. Trials in Germany, on
the upper Mosel, have produced a methode champenoise which is indistinguishable from good Champagne.
Time of bud-burst: early-middle
Strength of growth: medium, upright
Growth of side-shoots: medium
Flowering time: late
Flowering strength: medium-high (reliable)
Leaf: - size: medium to large
- shape: mostly 3-lobed to weakly 5-lobed,
slightly indented, blunt toothed
- colour:
- surface undulation:
- petiolar sinus: V-shape to closed
Grape bunch: - size: medium, cylindrical - density: quite tight
Berries: - size: medium-small
- shape: elongated
- skin colour:
green gold, thick skins
Time of veraison: early-middle
Time of harvest: middle-late, separate selective harvesting of lowest
bunches can be practiced (as with the Pinots)
Grape yield: medium-high
Must-weight: medium-high
Must-acidity: high
Wood ripening: good
Winter hardiness: medium to good
Wood colour: golden brown to red brown
Chlorosis resistance:
Susceptibility to - Oidium: medium
- Peronospora: low
- Botrytis: low-medium
- Roter Brenner:
-
Phomopsis:
- Stem-atrophy: medium
Preferred soil: all types but needs a lot of potash (K)
Suitable rootstocks: SO4, 5C. Not 5BB as this can cause
millerandage.
Normal stem height:
Normal row spacing: 1.8m to 2.0m, requires light and air so space well apart.
Vine spacing in the row: 1.6m, quite wide apart so the fruiting canes do
not overlap and cause a dense leaf-wall.
Winter Pruning:
eyes/buds per sq. metre of land occupied by the plant.
Advantages: Ripens well even in poor climate years. Yields
reliably every year.
Disadvantages: in some situations it can produce a 3rd and even a
4th cluster on a shoot. These bunches do not ripen as well so ideally need to be
removed early (soon after flowering).
