General information
Helios is a relatively new, fungus-resistant grape variety, developed at the Freiburg State Wine Institute (Germany) in the 1970s. The variety is known for its good disease resistance (mildew, oidium) and is primarily used as a wine grape. Its vigorous growth and healthy yields also make it attractive for small vineyards or organic cultivation.
Grape
The bunches are looser than some classic varieties, allowing for good air circulation and reducing the risk of mold development. The berries can be relatively large, and the bunches can become heavy under favorable conditions. The flavor is fruity, with a slightly characteristic note sometimes described as nutmeg-like.
Resistance
Helios shows good resistance to peronospora (downy mildew) and oidium (powdery mildew), and is relatively insensitive to botrytis and rot.
Wine
Helios produces a fresh, light white wine with fruity aromas and a distinctive character. The style is often compared to that of Müller-Thurgau or Pinot Blanc.
Helios wines are typically pale yellow in color and are distinguished by their fresh, fruity character. Typical aromas include ripe apple, pear, and white peach, often complemented by floral notes such as elderflower or chamomile. In favorable years, a subtle spiciness emerges, sometimes described as nutmeg or a light touch of honey. The acidity is mild to medium, giving the wine a soft, rounded character without being heavy. Helios thus produces an accessible wine with a pleasant bouquet, ideal for those who enjoy light and aromatic white wines with a touch of personality.
Cultivation advice
Its site requirements are similar to those of Pinot Blanc: a sunny spot with good drainage and sufficient shelter is ideal. Growth is vigorous but manageable, and the plant generally remains healthy, even with limited crop protection.
Planting out & planting distance
For planting distance, allow approximately 1 meter between plants in the row and 1.5 to 1.8 meters between rows, depending on the growth rate and cultivation system. Soil improvement, such as adding lava grit on calcareous soil or bentonite on sandy soil, can support growth.
Remark
Although Helios is sometimes used as a table grape in gardens or small vineyards, it was primarily developed as a vine variety. Its use as a table grape is possible, but is less frequently mentioned in professional literature.
