The winery is located in the municipality of Neumarkt (Egna) in the Italian wine-growing region of South Tyrol (Trentino-South Tyrol region). The manor house was built in the 17th century and received its present form in the second quarter of the 18th century. Around 1770, the Baron Longo family acquired the palace and incorporated it into the family's wine-growing estate together with the Villner Schlössl in the middle of the vineyards (see below). They had their own wine nursery as well as open wine sales in their own street tavern in Klagenfurt. The Palais Longo houses the estate's historic wine cellar, although most of it was redesigned in 2015. The estate, which was last owned by WG Neumarkt (now Kellerei Tramin), was finally taken over by Baron Anton von Longo Liebenstein from his father Felix in 2015.
The vineyards cover 20 hectares of vineyards planted with the white wine varieties Chardonnay,Pinot Blanc, Gewürztraminer, Sauvignon(Sauvignon Blanc), Solaris andPinot Gris, as well as the red wine varieties Cabernet Sauvignon, Merlot, Petit Verdot, Cabernet Franc and Lagrein. The cultivation is carried out according to the rules of organic viticulture; certified by ABICert since 2020. This includes the renunciation of irrigation, reduced fertilization (only for young plants) and the sowing of plants. Horses, sheep and chickens are kept in the vineyards. The yields are reduced by thinning out.
The product range includes wines with the names Felix Anton Terroir Line (aged in stainless steel) and Nobilis Line (from individual sites with ageing in wood and bottling without filtration). They are marketed as DOC Alto Adige and in different varieties as IGT Vigneti delle Dolomiti. In principle, they undergo spontaneous fermentation with yeasts from the vineyard. The red wines are aged in , the white wines in 500 to 2,500 litre containers. The white wine cuvée Liebenstein (Pinot Blanc and Chardonnay) and the red wine Wellenburg (Cabernet Sauvignon) are among the premium wines of the house.
