COS was started by Giusto Occhipinti with two classmates back in the early 1980s. On a shoestring budget, the three friends vinified the grapes from their parents' vineyards and created COS; an acronym of their last names. After experimenting with toasty oak and big flavours from over-ripe Nero d'Avola, they quickly realised that it wasn't the direction they wanted to go in. They then took a step back and started favouring concrete and amphorae. Their winemaking too changed, from modernism to non-interventionist wine making. Now they are well established as one of Sicily's leading exponents of biodynamic production and make wines of freshness and aromatic expression. COS does not use selected yeasts and has never used chemicals in the vineyards.
The colour is bright red, the nose ebullient with posies of violets, freesia and cherry-blossom. The palate is sweet and round, suggestive of raspberries and succulent cherries - the tannins barely evident.
