  • Components of a wine dispensing system

  • The key components of a keg and Bag-in-Box wine-on-tap dispensing system include:

    1. Keg or Bag-in-Box: The wine is stored in special wine kegs or in airtight bags (Bag-in-Box) designed to maintain the wine’s quality and freshness.

    2. Fittings and lines: Wine-specific fittings and lines are used to connect the keg or Bag-in-Box to the dispensing tap, ensuring proper wine flow and preventing contamination.

    3. Pressurization system: The pressurization system, which generally uses inert gas such as carbon dioxide CO2 and nitrogen N2, maintains constant pressure in the keg or Bag-in-Box to ensure proper dispensing and prevent oxidation of the wine.

    4. Dispensing tap: A tap specifically for wine, without filters or flow compensators, designed to dispense wine from kegs or Bag-in-Box, ensures correct handling and preservation of the wine’s quality.

  • Advantages of wine dispensers

  • Dispensing wine from kegs and Bag-in-Box on tap offers numerous advantages compared to serving wine from bottles:

    1. Waste Reduction: These systems eliminate the need for glass bottles, significantly reducing waste generation and environmental impact.

    2. Lower Risk of Oxidation: The use of inert gas and the system’s design protect the wine from oxidation, preserving its quality and freshness.

    3. Longer Shelf Life: Thanks to the pressurization system and storage in kegs or Bag-in-Box, the wine can maintain its quality for longer after opening, compared to bottled wine.

    4. Greater Service Efficiency: Wine-on-tap dispensing allows for faster, more efficient service, improving the customer experience.

    5. Efficient Storage: These systems take up less space than glass bottles, making storage easier and saving space in limited areas.

    6. Durability: Wine kegs and bags are strong and durable, reducing the risk of breakage and spills.

    7. Oxidation Prevention: The design of Bag-in-Box containers and kegs prevents air from coming into contact with the wine, ensuring its freshness.

    8. Safe Handling: These systems are easier and safer to handle than glass bottles, minimizing the risk of accidents and breakage.

    9. Controlled Temperature: Dispensers feature specific cooling systems to ensure the wine is served at the right temperature.

    10. Customization and Sustainability: Venues can customize presentation and reduce waste generation, promoting sustainable practices.

  • Maintenance and cleaning

  • To guarantee the quality and freshness of the wine dispensed, proper maintenance and cleaning of the system is essential. This includes regular cleaning and disinfection of lines and taps, checking fittings and seals, and maintaining the pressurization system.

    Installing and setting up a wine-on-tap dispensing system


    A wine-on-tap dispensing system is an innovative solution for serving wine in hospitality venues. The wine is stored in kegs or Bag-in-Box connected to the dispensing system, keeping it fresh and protected from light and oxygen.

    Inert gas, such as nitrogen, is used to pressurize the container and push the wine towards the tap. Cooling is carried out before service to maintain the correct temperature. The taps control the volume and flow rate, allowing for precise service.

    To install it, choose a suitable location, hire a professional, and ensure there is enough space and capacity for the kegs or Bag-in-Box. Connect the lines from the containers to the cooling unit and the taps. Adjust gas pressure and temperature. Perform tests and periodic maintenance for optimal operation and consistent wine quality.

    Preguntas Frecuentes

    Wine-on-tap dispensing from keg and Bag-in-Box is a method of serving wine stored in kegs or in hermetically sealed bags (Bag-in-Box) directly through taps. This method is an alternative to serving wine from bottles and offers advantages such as reduced waste, easier storage and a lower environmental impact.

    The components of a wine-on-tap dispensing system from keg and Bag-in-Box include the keg or wine bag (Bag-in-Box), the appropriate connections and tubing, the pressurization system (usually using an inert gas such as nitrogen or argon), a chiller for white, rosé and sparkling wines, and finally the dispensing tap.

    Wine-on-tap dispensing from keg and Bag-in-Box offers several advantages, such as reduced glass waste, less storage space, a lower environmental impact due to less packaging, a longer shelf life after opening and a lower risk of wine oxidation.

    The shelf life of wine in kegs and Bag-in-Box after opening can vary, but it is generally several weeks. The shelf life can be longer if a pressurization system with inert gas such as carbon dioxide (CO2) and nitrogen (N2) is used, which helps prevent oxidation of the wine and maintain a constant temperature.

    It is important to use a tap specifically designed for wine, made to dispense wine from kegs or Bag-in-Box. These taps are designed to handle wine properly and maintain its quality and organoleptic characteristics. For example, it is not necessary for these taps to incorporate filters or flow compensators.

    Generally, inert gases such as carbon dioxide (CO2) and nitrogen (N2) are used to pressurize wine in a dispensing system from kegs and Bag-in-Box. These gases do not react with the wine, do not carbonate it and help prevent oxidation while maintaining the wine’s quality.

    As with any dispensing system, it is important to carry out regular maintenance, such as cleaning and disinfecting the tubing and taps, as well as checking connections and seals. It is also important to ensure that the pressurization system is working properly and to maintain the correct pressure for the type of wine being dispensed.

    Red wines are made from red grapes and display a range of flavors from fruity and light to earthy and robust. They have a higher tannin content and are usually served at warmer temperatures than white and rosé wines. Some popular examples include Cabernet Sauvignon, Merlot, Pinot Noir and Tempranillo.
    White wines are made from white grapes and range from dry and acidic to sweet and fruity. They are lighter than red wines and are served at cooler temperatures to highlight their flavors and aromas. Chardonnay, Sauvignon Blanc, Riesling and Viognier are some examples of white wines.
    Rosé wines are made from red grapes but with limited skin contact during fermentation. This results in a pink-colored wine that combines characteristics of both red and white wines. Rosés can be dry or off-dry and are served chilled. Examples include Rosé de Pinot Noir and Garnacha Rosado.
    Sparkling wines are characterized by their effervescence, which is obtained through a second fermentation in the bottle or in a tank. They can be white, rosé or red and range in sweetness from brut (very dry) to sweet. Champagne, Cava and Prosecco are examples of sparkling wines.
    Fortified wines are wines to which alcohol, such as brandy, is added during or after fermentation, increasing their alcohol content and providing unique flavors and textures. Fortified wines can be red, white or rosé and vary in sweetness. Examples include Port, Sherry and Madeira.
