Silvanus' Secret at the ZHAW Zurich Olive Oil Award 2025: Certified Excellent Quality

Silvanus' Geheimnis at the ZHAW Olive Oil Award 2025: Excellent Quality Award

On March 19, 2025, our extra virgin olive oil Silvanus' Geheimnis (entry no. 017) was evaluated by the Swiss Olive Oil Panel (SOP) at ZHAW — Switzerland’s most rigorous sensory laboratory — as part of the Olive Oil Award Zurich 2025.

The results were extraordinary and confirmed this oil’s exceptional quality.

Official classification: Extra Virgin ✅

Evaluated according to European regulation EU 2022/2105:

  • Median defect: 0 — absolutely no detectable defects
  • Fruity: 5.6intense category, green profile
  • Bitter: 3.1 — balanced and characteristic
  • Pungent: 3.5 — present and elegant

The most important figures: Harmony 7.6 — Persistence 7.7
