With the innovative Infinity technology, wines and sparkling wines can be produced without oxygen exposure and without additives. The patented system saves winemakers a great deal of effort, time, and money.
The Moldovan winemaker Vitalie Popa and the German-Croatian barrel manufacturer Bruno Alexander Gantenbrink (owner of auric barrels d.o.o.) developed a new method for winemaking: the Infinity technology.
The innovative technology includes three revolutionary products for fermentation, maturation, and bottling of still and sparkling wines:
The Infinity technology enables still and sparkling wine production using only grapes (juice and/or berries), yeast, and bacteria—with no additives or preservatives. The anaerobic system prevents oxidation, contamination, and evaporation. It allows high-quality wine to be produced with fewer technological steps. The technology significantly reduces the workload for cellar masters and even allows small-scale and hobby winemakers to produce wine without any cellar equipment.
The technology is patented, and its effectiveness has been confirmed by Geisenheim University in 2021 and 2022. At Vinitech Sifel 2022 in Bordeaux, the Infinity technology won the Innovation Award. In June 2025, the inventors successfully presented their technology at the 46th World Congress of the International Organisation of Vine and Wine (OIV) in Chișinău.
Infinity Barrel
auric barrels d.o.o.The Infinity Barrel is a custom-made wooden barrel. It is gas-tight and pressure-resistant, preventing unwanted oxygen intrusion. A novel stainless-steel bung called the V-Bung ensures a perfect seal, eliminating the need for wine sulphuring.
Traditional wooden barrels are usually sealed with silicone bungs, which are not properly sealing the barrels and what need to be removed to take samples, for tastings, or topping up or SO2 correction—this is letting oxygen in. Additionally, oxygen can enter through the gaps between staves or due to fluctuating air pressure in the cellar. This is usually countered by adding sulphur dioxide.
The Infinity Barrel is reinforced with food-grade silicone rods between the staves. Instead of the conventional six riveted hoops, it uses eight adjustable hoops with bolts that exert equal pressure regardless of position. The Infinity Barrel features the V-Bung—a stainless steel bung with a clamp, overpressure valve, gas inlets, pressure gauge, height-adjustable spear, and a cooling/heating coil. The built-in spear allows to take samples by applying pressure, without removing the bung or exposing the liquid to oxygen. The cooling coil controls temperature throughout vinification. Cold stabilization can be made as well. Excess pressure escapes through the valve in the V-Bung. In a filled Infinity Barrel, pressure remains constant, enabling maceration, fermentation, malolactic fermentation, and aging under consistent pressure.
Due to the extremely low oxygen exposure during production and storage, the resulting wines are longer-lasting and immediately ready to drink. This allows winemakers to focus on grape quality—the more naturally the grapes are grown, the better the technology's advantages can be utilized.
Infinity HYBRID
auric barrels d.o.o.The Infinity HYBRID fermenter combines the Infinity Barrel with a custom-made stainless steel pressure tank and a perforated filter. Mounted above and connected to the barrel, the steel tank supports fermentation using only yeast and bacteria, accelerates fermentation and aging, and excludes any additives or preservatives. The system provides full control over oxidation, contamination, and evaporation. Its integrated perforated cylindrical filter enables fermentation of both liquid and solid components.
The Infinity HYBRID fermenter can be operated aerobically or anaerobically, with or without pressure. Adjustable temperature and pressure settings allow both pressure vessels to function independently or in tandem. Thus, fermentation can occur simultaneously in the wooden barrel and stainless steel tank and be combined at any stage by opening two valves. Multiple HYBRID systems can be linked in series to enable continuous fermentation, even allowing barrel switching during operation. Still and sparkling wines can be produced.
Infinity bottling technology
auric barrels d.o.o.The ABC is the first reusable bottling closure designed for anaerobic bottling. The closure is applied before the bottling process. The wine is filled through the closure itself.
The ABC features a housing, stainless steel spring, as well as inlet/outlet ports for gas and liquid. By using inert gases such as argon, nitrogen, or carbon dioxide, it ensures a stable anaerobic environment. The filling head can also serve as a dispenser, allowing sample extraction without removing the closure.
Its reusable design is sustainable and cost-effective, eliminating the need for disposable closures.
Infinity Pro
auric barrels d.o.o.Compared to conventional winemaking systems, Infinity Barrel, Infinity HYBRID and ABC offer numerous advantages:
Thus, the Infinity technology offers greater flexibility, higher efficiency, improved safety, and enhanced wine quality—with significantly less effort, time, and cost.
By the beginning of 2026, the Infinity Pro (30 to 50 liters) will be released to the market. This enables winemakers, research centers, and universities to perform advanced trials on smaller volumes.
