How the Patented Preservation Technology Works
The Wikeeps® patented approach uses a system that injects a food-grade inert gas mixture of argon and CO₂ into opened wine bottles through a specialized dispenser gun. This creates a protective atmosphere that is completely neutral for taste and smell, sheltering the wine from oxidation and air contact. The gas is supplied by Linde, the world leader in oenological gases, ensuring quality and consistent performance across every cartridge.
Each cartridge contains 21 ml (6.5 g) of the argon-CO₂ blend and can preserve a minimum of 18 glasses—equivalent to three standard 75 cl bottles. Independent French laboratory tests confirm that wines preserved using this patented preservation system maintain their aromas and sensory qualities for more than 20 days, with proven effectiveness extending to over 30 days depending on storage conditions. This extended shelf life represents a significant advantage for wine bars, restaurants, and home enthusiasts who want to serve premium bottles without waste.
Product Applications and Preservation Solutions
The Wikeeps® patented preservation concept supports multiple wine service scenarios. For still wines—red, white, rosé, and sweet varieties—the Essential Kit provides a complete patented wine preservation solution with a dispenser gun, Elite tap, filter, preservative caps, and gas cartridges. The kit enables vertical service while preventing oxidation, allowing restaurants and wine enthusiasts to preserve opened bottles with confidence.
For those seeking a more comprehensive solution, the wine preservation system approach offers enhanced flexibility through specialized kits designed for professional wine-by-the-glass service. These systems integrate temperature control options and can accommodate multiple bottles simultaneously, making them ideal for upscale establishments seeking to showcase premium selections without compromise to quality or shelf life.
The patented technology also extends to sparkling wines and champagne through specialized systems that maintain effervescence and prevent oxidation. Using patented Smart Cap stoppers and specific gas capsules (CO2 + Nitrogen), this application preserves the bubbles and aromatic complexity of champagne, Cava, Prosecco, and Franciacorta for more than seven days—a breakthrough in sparkling wine preservation that protects both investment and pleasure.
Cartridge specifications and gas packaging standards
Each Wikeeps® cartridge represents precision packaging of oenological gas designed to meet the strictest food-grade standards. Manufactured in the European Union, cartridges contain a carefully calibrated 21 ml (6.5 g) mixture of argon and CO₂, supplied by Linde Gas under collaborative development agreements with Wikeeps®. This patented gas composition is derived from air and has been tested and proven in the cellars of the world’s finest vineyards.
The dispenser gun mechanism delivers this protective gas through simple finger pressure, creating an instantaneous protective atmosphere inside the bottle while pouring. This innovation means that both service and preservation occur simultaneously—eliminating the need for complex equipment or installation. The system works seamlessly with traditional decanting methods for grand crus and pairs with professional wine service protocols used in Michelin-starred establishments.
Patent protection and industry recognition
The Wikeeps® patent registration under INPI number FR2945526 (AI) provides legal protection against counterfeiting and unauthorized use of the innovation. This formal recognition ensures that the patented preservation method remains exclusive to Wikeeps®, protecting the integrity of the brand and the technology that enables premium wine service worldwide.
Beyond patent protection, the Trophée Œnovation® 2012 award validates Wikeeps® as a transformative innovation in wine service. The award acknowledges not just the technical excellence of the patented preservation system, but its practical impact on the wine industry—enabling restaurants, wine bars, and enthusiasts to serve premium bottles with confidence while extending shelf life and minimizing waste.

What makes the Wikeeps® patented preservation system different from other wine preservation methods?
The Wikeeps® patented system uses a food-grade argon-CO₂ gas mixture developed with Linde to create a protective atmosphere that prevents oxidation while remaining completely neutral for taste and smell. Unlike cork stoppers or vacuum sealers, this patented preservation approach shelters wine from air contact without altering the wine’s organoleptic qualities—the gas itself is air-derived and used by the world’s greatest châteaux. The INPI patent registration (FR2945526) protects this unique innovation against counterfeiting, ensuring authenticity and consistency in every application.
How long does the Wikeeps® patented preservation system keep opened wine fresh?
Independent French laboratory testing confirms that wines preserved with the Wikeeps® patented technology maintain their aromas and sensory qualities for more than 20 days, with proven shelf life extending to over 30 days for still wines under optimal storage conditions. Each 21 ml cartridge preserves a minimum of 18 glasses (three 75 cl bottles). For sparkling wines, the specialized system preserves effervescence and complexity for more than seven days—a significant extension compared to traditional cork or cage methods.
What types of wines can be preserved using this patented system?
The Wikeeps® patented preservation system works with all still wine varieties: red, white, rosé, and sweet wines.
