The
adding of SO2 : a useless debate "We are often asked if we add SO2 to our wines and if yes, how much. Many are of the opinion that Biodynamic means wine making without SO2. This is incorrect. Here at Montirius, we think that it would be wrong to not use it. There are two reasons. Firstly, SO2 is an excellent product for conserving. Certainately, for wines for which a natural acidity is important (e.g. champagne which has a low PH) adding SO2 is over the top; the tartaric acid naturally present protects it from oxidation. However, for wines that have a lesser natural acidity (which is the case of the Montirius wines), they are more sensitive to the air. Also, some choose to add tartaric acid to protect their wines. We refuse to do this, as we consider it changes the nature of the wine. We prefer to add SO2 which does not alter the nature of the wine. It encourages effectively the selection of the ‘good natural’ yeasts (All sorts of natural yeasts are to be found on the skin of the grapes). These yeasts will transform sugar to alcohol. Once the wine is bottled, the systematic adding of SO2 allows the wine to continue to improve. The second reason is by the time you drink one of our Montirius wines, the SO2 which we added systematically, will have, for the most part, disappeared. In fact, the official laboratory for AOC wines, that helps us with analysis and advice, did some research on a biological domain at Chateauneuf du Pape. The research showed that after only one year bottled, the ‘free’ SO2 (the added SO2, contrary to the combined SO2, the ‘total’ SO2) had dropped by 50%. After 3 years bottled, the free SO2 was ‘NIL’." Man anfører analyser af Vacqueyras Le Clos 2006 "Bottled in 2008 - Free SO2 on 18/07/08 = 73 mg/l On the 1/07/10 (start of sale) = 9mg/l (very low)" og fra Gigondas Terre des Ainés 2006: "Bottled in 2008 – Free SO2 on 08/08/2008 = 69 mg/l On the 1/07/10 (start of sale) = 6mg/l (very low)" "Within the 2 years the free SO2 that we added has almost disappeared. In fact our wines are generally drunk a minimum of 3 years after bottling. At this date it is more than likely that the wine does not contain a trace of free SO2." |
