The Invernenga grape variety is an indigenous white grape from the province of Brescia, whose origins are unknown. It was first mentioned in a document from the Ministry of Industry, Agriculture, and Commerce of the Austro-Hungarian Empire in 1826, which described Invernenga as one of the most cultivated grape varieties in the Brescia area. Its name seems to derive from the fact that its grapes, with a typical almond aftertaste and thick skin, harvested late, have the peculiarity of being able to be stored for a long time, allowing them to be consumed during the Santa Lucia and Christmas holidays as table grapes in the past. Its distribution is limited to very few areas in Bresciano, with few and isolated rows, mostly within very old vineyards.

The Invernenga grape variety has been registered since 1971 in the National Register of Vine Varieties, and as a single varietal, it is present as the only wine with a typical geographical indication, Ronchi di Brescia IGT. The berry of the Invernenga grape is medium-large, with a thick, consistent yellow-green skin. Its ripening occurs between the end of October and the beginning of November. The wine obtained from Invernenga, once used to enrich wines with low alcohol content and weak structure, is also excellent for the production of sweet wines. It has an intense straw yellow color with golden reflections and good consistency. On the nose, it has very delicate floral and fruity scents, with aromas of honey and slight aromatic hints. On the palate, it has good structure, more savory than acidic, finishing with a fairly pronounced almond aftertaste. It is suitable for long aging in the bottle, and during aging, it fully expresses its organoleptic characteristics. It is an ideal wine for pairing with lake fish, delicate cheeses, and white meats.
