variable capacity wine tank
Variable capacity wine tanks are specialized fermentation vessels that allow winemakers to adjust the volume of the tank according to the amount of must or wine being processed. This flexibility is particularly beneficial for small batches or varying production levels, as it helps optimize space and resources.
The floating lid tank from CHENMA is an innovative solution designed to meet the diverse needs of modern winemaking. This tank offers a range of features and benefits that enhance the fermentation, storage, and aging processes of wine, making it a valuable asset for wineries of all sizes.
Design Features of variable capacity wine tank
Benefits of Variable Capacity Tanks
Winemakers can adjust the tank volume based on production needs, allowing for smaller batch sizes without requiring multiple tanks.
Temperature Control
These tanks facilitate better temperature regulation during fermentation, which is vital for preserving wine quality.
Reduced Oxidation
The adjustable floating lid minimizes headspace, reducing exposure to air and preventing oxidation during fermentation and aging processes.
Space Efficiency
By accommodating varying volumes without needing additional storage space, these stainless steel open top tanks help wineries maximize their operational efficiency.
Variable Capacity Tanks for Different Wine Types
Variable capacity wine tanks are increasingly popular across various types of wines due to their versatility and efficiency in managing fermentation and aging processes. Their performance can vary significantly depending on the type of wine produced. Here’s an overview of how these tanks function with different wine varieties:
Temperature Control: Red wines are typically fermented at warmer temperatures (18-32°C) to enhance tannin extraction and color development. Variable capacity tanks facilitate temperature regulation, which is crucial for achieving the desired flavor profile and mouthfeel.
Cap Management: The solid components (skins and seeds) create a “cap” during fermentation. Variable tanks allow winemakers to perform techniques like punch downs or pump overs to manage this cap effectively, ensuring optimal extraction of color and tannins without over-extraction.
Oxygen Exposure: Some variable tanks are designed to permit controlled oxygen exposure, which can soften tannins and enhance complexity in red wines. This micro-oxygenation is particularly beneficial during aging.
Cooler Fermentation: White wines are generally fermented at lower temperatures (12-16°C) to preserve delicate aromas and flavors. Variable capacity tanks can be equipped with cooling jackets to maintain these lower temperatures throughout the fermentation process.
Stainless Steel Material: Stainless steel tanks are commonly used for white wine fermentation due to their non-reactive nature.
Flexible Volume Management: These tanks can be partially filled, allowing wineries to produce smaller batches without compromising quality, making them ideal for boutique wineries focusing on premium white wines.
Secondary Fermentation: Sparkling wines undergo a secondary fermentation in the bottle or tank to produce carbonation. Variable capacity tanks can be used for this process by allowing winemakers to control the pressure and temperature, which are critical for achieving the right level of effervescence and flavor complexity. This is crucial for achieving the desired effervescence and flavor profile.
Yeast Management: The choice of yeast strains is crucial in sparkling wine production. Variable capacity tanks enable winemakers to experiment with different yeast types and fermentation conditions, impacting the final flavor profile significantly.
Ease of Racking: The design allows for easy racking of the wine, which is important in sparkling wine production to remove sediment without introducing oxygen.
Minimal Intervention: Natural wines often rely on wild yeasts and minimal additives. Variable capacity tanks can support this approach by allowing winemakers to control environmental factors while promoting the growth of indigenous yeast populations.
Monitoring: The ability to monitor fermentation closely without opening the tank reduces exposure to air, preserving the unique characteristics of natural wines.
Flexibility in Fermentation Conditions: These tanks offer flexibility in managing fermentation conditions such as temperature and oxygen exposure, which can lead to unique flavor profiles that reflect the terroir more authentically.
CHENMA VCT Manufacturing Process
Material Preparation:
The tanks are primarily constructed from AISI 304 stainless steel, known for its durability and resistance to corrosion. For environments with higher corrosive potential, AISI 316L stainless steel is also available.
Finishing:
The exterior of the stainless steel wine tanks can be finished in various styles, including high-polish, matte, or Scotch Brite finishes, while the interior is polished to a BA (IIId) standard to facilitate cleaning and maintenance.
Quality Control:
Throughout the production process, stringent quality control measures are implemented. Each variable capacity wine tank undergoes thorough inspections to ensure it meets industry standards for safety and functionality. Tanks are tested for airtightness and structural integrity before being released for sale.
Welding and Assembly:
The stainless steel sheets are cut and shaped into the desired tank dimensions using advanced fabrication techniques. This includes laser welding for creating strong and precise joints. The bottom of the tank may be conical or flat, depending on the design requirements for effective drainage.
Installation of Components:
After fabrication, components such as the floating lid, inflatable gasket, ventilation systems, conical bottom, and cooling jackets are assembled. The floating lid is equipped with a mounted lifting arm and a stainless steel hand pump to facilitate easy operation. Each component must be precisely fitted to ensure proper functionality.
Installation:
After fabrication, CHENMA team assists with the installation of the custom-built tanks. This includes setting up all necessary processing equipment and handling any field fabrication required on-site. The installation process is designed to optimize the functionality of the tanks within the winery's existing infrastructure, ensuring that winemakers can immediately benefit from their new equipment.
