The inStabiles series of wines are, according to Arribas, free wines: individual releases ordered in a series by number and each receives its own subtitle. The wine itself is an opportunity for Arribas to free himself to experiment only within the confines of vintage and the origin of the fruit that include Morera, Torroja, and higher vineyards in Lloar. He sees each inStabile release as an exercise in assemblage, selecting from an array of unique methods and vessels available in his cellar. The unifying principle is navigating the wine trail itself by selecting wines that, when combined, evoke subtlety and weightlessness through craftwork.
In the cellar, fermentations are spontaneous and preserve whole clusters employing either carbonic macerations or short traditional macerations so as not to over-extract tannins. Three milligrams of sulfur are added before bottling to stabilize the wines and ensure quality after transport. Almost no oak is used in fermentation or �levage, instead a small amount of the wine stays in small stainless while the majority of wine is fermented and aged in cement eggs or clay amphorae of varied sizes and shapes.
