Be in a hurry, because tickets are sold out in advance usually.
Tickets usually include free live tasting of all the exhibited wines and coupons for purchase of one or two bottles of wine. Each participant get a wine glass with a bag and a list of open wine cellars.

For current Days of open wine cellars see a website of The Small Carpathian Wine Route.
