In our quest at the winery for a carbon neutral impact on our climate, we are always looking for new ways to green our packaging and eliminate waste. In 2013, we began a campaign to modify our wine labels to use 100% post-consumer waste, FSC-certified papers. Now in 2015 we are beta testing a new style of wine bottle closure that is the world’s first closure with a zero carbon footprint. The Select Bio closures from Nomacorc are made with renewable plant-based biopolymers derived from sugarcane. This innovative technology prevents cork taint and oxidation, the closures are produced with 100% renewable energy, and they are 100% recyclable.
Nomacorc's Select Bio closures made from non-GMO sugarcane.
The sugarcane used in the Nomacorc line is grown on non-GMO plantations in Brazil. The sugarcane fields are dry-farmed and replace degraded pastureland, helping to recover soil erosion and increase the carbon content within the depleted soil. Residues from production are closed-looped: they are recycled as fertilization or turned into “bagasse,” a sugarcane bi-product used to produce energy.
Another exciting feature for us is that the Select Bio closures are Demeter® certified. Select Bio closures conform to Demeter’s functional specifications for Biodynamic wines, including the stipulations that a Biodynamic® product must not come into contact with packaging containing chlorine, herbicides, or pesticides.
Our current corks are made from compressed cork shavings fused with a food-based polymer. We have experienced many years of success with them, but we’re always looking for ways to improve our practices with the least amount of environmental impact. There is a general assumption in the wine industry that 3-5% of all wine bottles using a natural cork show some signs of spoilage. The most common reason for spoilage is from oxygen ingress that can occur through the space between the bottle neck and the cork, or through the cork itself. In the case of unsulfited wines like ours, oxygen is a particular culprit in affecting the delicate nature of the wine, so finding the proper closure is imperative. We will be running trials with the Select Bio closures over the next year to ensure that this is the right choice for us.
