Discover new grape varieties with your group

An offer for 12 to 35 persons

Bookable from May to September

The "Grünhag" vines of the organic vineyards Bosshart & Grimm are within 5 minutes walking distance from the tunnel. The tasting is therefore a wonderful complement to a group experience underground.

During the tour and in discussions with the winegrowers you will learn exciting facts about the vineyard, climate, terroir, biodiversity and the careful care of the vines.

For newcomers as well as wine connoisseurs it remains interesting, because we are talking about special fungus-resistant PIWI grape varieties, white Saphira, Johanniter, Solaris and red Cabernet Jura, which are hardly found elsewhere in our area.



  • For 12 to 25 persons, CHF 26 per person
  • each additional person CHF 20 (max. 35 pers.)

  • Bread and mineral water


  • 90 minutes, start 10.30 am, 1.30 pm or 4.30 pm
