RITON

The 'Riton' grape variety is a technical hybrid developed to combine high yields with exceptional climatic adaptability. Bred by a dedicated team (Bazelev, Poymanov, Gubin, and Olar), this variety stands out due to its remarkable frost resistance, enduring temperatures as low as -27°C, which secures its place in cold-climate viticulture.

Agronomic and Technical Profile

• Growth dynamics: The vine shows strong vigor, requiring robust trellis systems and precise canopy management to ensure optimal airflow and light penetration.
• Yield and quality: With cluster weights ranging from 500g to 800g and individual berries weighing 2–5g, Riton provides a high juice yield. The white fruit profile is characterized by distinct fruity notes, which are highly valued in technical winemaking.
• Ripening cycle: Classified as mid-late, the variety needs appropriate heat summation to achieve technological maturity.

Disease Management and Resistance

Riton exhibits high resistance to downy mildew (mildew), which significantly lowers the need for intensive fungicide spraying. However, the variety is sensitive to grey mold (botrytis) and shows moderate susceptibility to powdery mildew (oidium). Practical management requires strict adherence to seasonal prophylactic schedules and canopy thinning, especially during the veraison period, to maintain fruit health and prevent mold development.
