The starting point was Popa\u2019s desire to move away from sulphites and other additives in wine, which can act as allergens. His years of experience in Australian and New Zealand wine production led him to this idea. Planning and development began about seven years ago, and in 2021, Gantenbrink joined the project to produce the first trial series of the innovative barrels. Now, the partners are presenting their patented innovation \u2013 the auric infinity barrel \u2013 at SIMEI 2024 trade fair in Italy in mid-November.<\/p>\n<h2>What makes this barrel unique for winemaking?<\/h2>\n<p>In conventional wine barrels, the bung is typically made of silicone. During winemaking and aging the closure needs to be removed for various tasks, leading to oxidation, evaporation, and contamination of the product. Changes in air pressure and humidity in the wine cellar create positive or negative pressures inside the barrel, significantly affecting the sealing of the barrel\u2019s silicone bung. The traditional barrel design with silicone bung does not adequately address these challenges. The innovative auric infinity pressure fermenter resolves all issues associated with conventional closures and enables wine production using only grapes, yeast, and bacteria. After years of research and development, this new barrel technology is entering the market. The system allows sampling without oxidation, contamination, or evaporation, marking a revolution in winemaking in wooden barrels.<\/p>\n<p>&nbsp;<\/p>\n<blockquote><p>If you can drink quality wine without additives, who will still choose conventional wine?<\/p><\/blockquote>\n<p style=\"text-align: right;\"><span style=\"color: #339933;\">Vitalie Popa, Vinemaker und auric-infinity-developer<\/span><\/p>\n<p>&nbsp;<\/p>\n<div class=\"su-row\"><div class=\"su-column su-column-size-2-5\"><div class=\"su-column-inner su-u-clearfix su-u-trim\">\n<div id=\"attachment_6268\" style=\"width: 522px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-6268\" class=\"alignleft wp-image-6369\" src=\"https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021.jpg\" alt=\"\" width=\"512\" height=\"683\" srcset=\"https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021.jpg 1400w, https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021-225x300.jpg 225w, https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021-768x1024.jpg 768w, https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021-1152x1536.jpg 1152w, https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021-1300x1734.jpg 1300w, https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/image00021-300x400.jpg 300w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/><p id=\"caption-attachment-6268\" class=\"wp-caption-text\">The cross-section clearly shows the special features of the new type of cask.<\/p><\/div>\n<\/div><\/div>\n<div class=\"su-column su-column-size-3-5\"><div class=\"su-column-inner su-u-clearfix su-u-trim\">\n<h2>Fermentation in a wooden barrel at constant pressure<\/h2>\n<p>The auric infinity barrel allows for wine production using only grapes, yeast and bacteria under controlled, continuous pressure. This is where HEROSE plays a role in pressure regulation. While searching for a suitable partner for the groundbreaking barrel, Popa connected with HEROSE. The requirements called for a compact solution which optimally removes the resulting carbon dioxide and thus regulates the pressure. Additionally, the valve needed to be able to ventilate when necessary. Based on type 06205 pressure relief valve, the body, bonnet, and spindle were adapted and a pull ring was added. The disc and guide remained unchanged. In close collaboration with auric barrels, this customer-specific adjustment was successfully implemented. Gantenbrink particularly highlights HEROSE\u2019s pragmatic approach and willingness to adapt to customer needs.<\/div><\/div><\/div>\n<h2>The quality of the barrels for winemaking begins in the forest<\/h2>\n<p>The wood used is crucial to the quality of the barrel. Premium wood from sessile oak and pedunculate oak is used, which has excellent durability under oxygen-free conditions, making it ideal for the production of wine and whiskey barrels. Alexander Gantenbrink has access to his own forest in Croatia, where he practices sustainable forestry. The journey from tree to barrel is long. The trees grow for around 120 to 140 years, after which the wood is cleaved, cut, and left to air-dry outdoors for at least 24 months for the standard 225-litre barrique barrels. In the first three months, the wood is also soaked to prevent it from drying too quickly and to wash away the green, undesirable tannins from the wood. This process removes bitterness through exposure to the elements. Due to the forest mapping system, complete traceability of the raw materials is possible. Each barrel\u2019s wood can be traced back to the exact tree location via a barcode.<\/p>\n<h2>Between craftsmanship and 3D CNC milling robots<\/h2>\n<p>The rounded geometry of a classic barrel poses a manufacturing challenge. The outer diameter contains more material than the inner, and each stave has a curved shape.<\/p>\n<p>A CNC machine mills a 3D geometry into the staves. auric barrels\u2018 factory, located in Na\u0161ice, Croatia, has been in operation since 2016 and is one of the most modern in Europe. Thousands of staves of Slavonian oak are stored on-site for barrel production. In addition to the new auric infinity barrel, standard barrels in sizes from 50 to 6,000 litres and fermenters up to 40,000 litres are sold worldwide.<\/p>\n<h2>Tested and approved<\/h2>\n<p>Naturally, Vitalie Popa and Bruno Alexander Gantenbrink have produced their own wines using the new technology. A much-praised Chardonnay, for example, was ready for consumption after just 8 weeks \u2013 without any added sulphites or additives, which are known to cause headaches and the typical \u201ehangover.\u201c To independently test the performance of the auric infinity technology, four barrels were provided to Geisenheim University in Germany, which specializes in viticulture and wine business. Their detailed report fully confirmed the technology\u2018s capabilities. The trials also revealed that yeast cells exposed to sunlight develop significantly stronger cell walls.<\/p>\n<p>&nbsp;<\/p>\n<blockquote><p>We believe our development will fundamentally change barrel-winemaking.<\/p><\/blockquote>\n<p style=\"text-align: right;\"><span style=\"color: #339933;\">Bruno Alexander Gantenbrink, CEO of auric barrels<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2>A revolutionary and versatile technology in winemaking<\/h2>\n<p>With auric infinity barrels, almost any wine enthusiast can produce their own wine from grape juice, yeast and bacteria. The process is simplified as sulphites and other additives are no longer needed. An online course will be available to provide interested parties with the necessary knowledge. To kick-start the business, auric is offering the first 2,000 infinity 225-litre barrels for \u20ac2,000 each. There is also an affordable method for anaerobic bottling using special patented screw caps that are part of the filling technology. While wine production is the first application for this new technology, the method of fermenting in wood under constant pressure is also of interest for beer, cider, vinegar, and other products. It remains to be seen how the market will respond to the new technology. The positive feedback from those who have tasted the additive-free wine raises high expectations.<\/p>\n<h3>auric barrels<\/h3>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6355 size-full\" src=\"https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/B53EFB42-4823-4DD8-BBFE-8D8DB792A35F-e1731406517400.jpg\" alt=\"\" width=\"500\" height=\"331\" srcset=\"https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/B53EFB42-4823-4DD8-BBFE-8D8DB792A35F-e1731406517400.jpg 500w, https:\/\/www.valves-community.com\/wp-content\/uploads\/2024\/11\/B53EFB42-4823-4DD8-BBFE-8D8DB792A35F-e1731406517400-300x199.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<p>Im kroatischen Na\u0161ice steht eine der modernsten Fassfabriken Europas mit neuestem Maschinenpark, erfahrenen Handwerkern und umfangreichem Holzlager slawonischer Qualit\u00e4tseichen.
