The Importance Of Managing Humidity In Wineries

When you think of wineries, what comes to mind? Perhaps picturesque vineyards with centuries-old traditions? You're not alone. That image still holds for many. But as the world evolves, so does how we make wine.

While the basic process hasn't changed in millennia, reducing waste and boosting efficiency is as crucial for wineries as any other business. After all, staying profitable is a universal challenge.

One aspect of this evolution is the wine aging process. Unlike those blessed with underground cellars, above-ground wineries must now master controlling temperature and humidity. Commercial dehumidifier are reshaping the very essence of this age-old craft. 

In a world where technology can mean the difference between a 14 percent loss to evaporation over two years and nearly none at all, the right humidification system can have profound effects on wineries.

Here's how dehumidifiers are changing the wine making process.

Reducing Evaporation Rates

In winemaking, the aging process is a delicate balance between preserving the essence of the wine and preventing unnecessary loss. Wine barrels, often crafted from organic materials like wood, have a unique relationship with the surrounding environment. They not only influence the wine's flavor and bouquet, but they are also sensitive to the moisture content in the air.

That's why when there is no sufficient humidity, these wooden casks act as thirsty conduits, allowing the wine to evaporate slowly. Winemakers refer to the evaporated wine as the "Angel's Share." And to avoid losses, they often combat this natural process through a practice known as "topping off," a method of replenishing wine that has evaporated into thin air. However, this evaporation isn't merely about the quantity of wine; it also affects the wine's alcohol content and quality.

Traditionally, winemakers enjoyed an advantage by aging their wines in underground cellars where humidity levels remain consistently around 60 percent. However, modern winemaking facilities have embraced an innovative solution - industrial humidification systems. These systems maintain a relative humidity level between 70 and 95 percent, significantly reducing evaporation. This reduction minimizes the need for constant topping-off, which translates to lower production costs and a decreased risk of inadvertently blending different batches.

Eliminates Mold And Other Contaminations

Contamination is a battle winemakers face, especially in overly damp regions. Wine barrels–constructed from organic materials, create the perfect breeding ground for mold and other airborne bacteria in high humidity and dark spaces.

The challenge with older humidifiers? They used to produce “wet fog,” which could settle on surfaces within the winery, potentially leading to contamination. But thanks to new technologies, there's a game-changer: "dry fog." It's composed of tiny 4.2-micron water droplets that ensure 100 percent evaporation. These minuscule water particles won't stick to the wine barrels. Plus, smart sensors and innovative distribution techniques keep humidity levels steady.

With this high-tech guardian, mold and other contaminants stand no chance. 

Regulatory Compliance

Besides contaminations, wineries must adhere to stringent regulations and standards related to both environmental conditions and product quality. These regulations ensure that the end product is of the highest quality and safety. Humidity control through commercial dehumidifiers can help you meet these regulatory requirements.

Lower Energy Consumption By Easing Load On Your HVAC

Apart from regulating humidity, temperature control is also crucial. Unfortunately, wineries often rely on hefty heating and cooling systems to maintain a consistent climate, which can be costly. Although dehumidifiers cannot regulate the temperatures as efficiently as they can humidity, they can be energy-saving heroes.

How do they do it? By regulating humidity levels. As a result, they ease the load on HVAC units, making them draw less power. The result? Lower operating costs, a longer HVAC lifespan, and fewer maintenance headaches. Your winery runs smoother with more stable temperature control.

Improve Conditions During Labeling and Packaging

Dehumidifiers play a crucial role in ensuring that the conditions for labeling and packaging are optimal. They help maintain the integrity of wine labels and packaging materials, preventing label peeling, mold growth on packaging, and deterioration of cork seals.

Additionally, dehumidifiers facilitate a quick turnaround for the cellar, making it ready for use again after cleaning.

Humidity In Wineries FAQs

What is the ideal humidity level for a wine cellar?

The ideal humidity level for a wine cellar typically falls within  50% to 70% relative humidity. This range helps preserve wine quality and prevents cork drying, which can lead to oxidation.

How do dehumidifiers impact the Angel's share?

Dehumidifiers help control humidity levels, reducing the evaporation of wine and spirits. So, they help maintain the quantity and quality of the wine stored in the cellar.

What are the potential consequences of mold growth in wineries?

Mold affects wine packaging and leads to off-flavors and spoilage, which can result in significant financial losses for wineries.

What is the ideal humidity for fermentation?

The ideal humidity for fermentation in winemaking typically falls within 70% to 90%. This range provides the necessary moisture content to support the fermentation process. However, you should monitor and adjust humidity levels to suit the specific requirements of the winery and the type of wine you produce.

Bottom Line: Humidity Control in Modern Wineries

Wineries continue to follow the same production methods that have been there for centuries. However, building new underground facilities like the ones used by traditional wineries to control humidity is costly. That's why many turn to climate-controlled buildings for aging wine. However, fluctuating humidity can spell trouble.

This is where industrial humidifiers come into play, offering innovative solutions that save money for modern wineries. By fine-tuning and preserving the correct humidity, these advanced systems reduce the need for constant "topping off," cut down on energy usage, and eliminate contaminants.
