The story
Birch sap, known in Italian as *linfa di betulla*, is a clear, slightly sweet liquid harvested from birch trees in early spring. Tapped directly from the trunk before the leaves emerge, the sap flows for only a few weeks each year, making it a seasonal delicacy prized for its delicate flavor and purported health benefits. The practice of collecting birch sap has deep roots in Northern and Eastern Europe, where it has been consumed for centuries as a refreshing tonic.
A great version of birch sap is distinguished by its purity and freshness. Ideally consumed within days of tapping, the finest sap is crystal clear with a subtle sweetness and a faint, woody undertone. It should be free of any cloudiness or off-flavors, which can develop if the sap is not stored properly. Some producers lightly pasteurize it to extend shelf life, but the most prized examples are raw and unprocessed.
In Italy, birch sap is less common than in Nordic countries, but it has found a niche among foragers and gourmet chefs. At **La Tana Gourmet** in Asiago, Italy, the dish is featured as a highlight, with the venue noting its seasonal availability and natural purity. The sap is often served chilled on its own or used as a light, aromatic base for cocktails, syrups, and desserts. Regional variations include fermenting the sap into a mild alcoholic beverage, similar to birch wine or beer, or reducing it into a syrup akin to maple syrup, though with a more subtle, herbal sweetness.

Alessandro Dal Degan's cuisine is a super personal one that reworks the territory, taking cues and influences both from the Lagoon, which is very close by, and from the travels he takes around the world. There are a lot of ups and downs, definitely don't get bored, don't expect the classic bread and butter. I also really liked the pairing. There were alcoholic and non-alcoholic cocktails. They not only accompanied the dishes but complemented, dare I say, the dishes. The menu changes every season so we show you this menu because the chef's philosophy is to start over every season to question yourself. And, I would add, if you come to this place, accept that you are not in control of the situation because not everything will be explained to you, you will not have a menu in your hand and you will not know what will come. Among my absolute favorite dishes, radicchio and also its accompanying drink. I loved the mackerel. Franci, even if it doesn't seem like it because she says it with a bit of sadness, really liked the mackerel. We easily spent 700 because the menu costs 350, pairing included. It's not a little. In my opinion, it is worth climbing up here to try cuisine that you will never find anywhere else.
