The name itself is of interest: Osmizze (also Osmize, Osmica) is a word based on the Slovenian osem, which means "eight". A short history of the custom of Osmizze will explain... Historians can trace the existence of osmizze back to medieval times in a document from 1430 shows that wine sold in bulk by peasant producers near Trieste would not be taxed. This was reinforced in 1784 by Joseph II of Hapsburg who decreed that farmers could sell bulk wine from their homes for periods of eight days each year. The custom stuck, only nowadays, the farmers themselves decide when they are open or not. They are also opened all year round, with the warmer months being favored due to the beautiful weather to enjoy the al fresco experience.
This is where the fun starts. You see, Osmizze don't advertise. They don't have prime locations on the main roads. They are located in the countryside and amid the suburban sprawl outside of Trieste and around the towns of Longera, Piscianzi and also across the border in Slovenia. As you drive trough the area by car or bicycle (a very popular way of seeing the area) you will start to see a small wooden arrows with a cutting of ivy branches tacked to poles, walls or fences. It's sort of like when you follow a series of signs in the U.S., like way-points, to find a remotely located barn sale. There will be several signs leading you to the osmizza. When you arrive, don't be surprised at how unassuming it might appear. You might at first think you're in the wrong place, and trespassing into someone's home. But that's the point. These are peoples' homes.
