Our Love Collection showcases California’s best organically farmed and unsung grape varieties at an affordable price. All Broc Cellar wines are made using spontaneous fermentation, which means only native yeasts and bacteria that exist on the grapes are used to make wine. We don’t add anything – this includes nutrients, yeast, bacteria, enzymes, tannins or other popular fermentation agents. Sulphur is a naturally occurring element in all wine, the amount found can vary. Sulphur is never added during fermentation and aging. We add little to no S02 at bottling, depending on the wine, year and style.
