It was a very exciting day here at RFE we had the pleasure of welcoming Edina Kiss from Vinventions, to put ZEST! The first sparkling wine closure with certified zero-carbon through its paces and it was amazing. We are very proud to be using this type of closure that eliminates the risk of TCA and is one whole, solid piece. Zest! uses renewable, plant-based polymers derived from sugar cane. Made with food grade materials that protect flavour, colour and aroma. This helps us on the way to be more sustainable and working towards a 100% recycled product from bottle through to labels and now corks.
