Cider Corner: Cold Space & Glycol Management Tips

Achieving a perfect balance of flavors and maintaining consistent quality are paramount in cidermaking. It’s a delicate process that requires meticulous attention to detail, particularly in the management of cold space and glycol systems.

The careful control and monitoring of temperature throughout production and storage areas are crucial for preserving the freshness and integrity of the product. That, along with glycol management, plays an indispensable role in upholding a high cider standard, underscoring the significance of careful oversight. The use of furnaces in conjunction with glycol systems allows for precise temperature control, ensuring that the cider remains at optimal conditions throughout production.

By effectively utilizing these systems, cider producers can prevent fluctuations that may compromise flavor and quality. Properly managing the cold spaces in the facility not only enhances the overall production process but also safeguards the unique characteristics that make each batch special.

However, achieving this level of precision requires regular maintenance and timely interventions. That’s where furnace repair becomes critical. Regular inspections and repairs of the furnace systems ensure they operate efficiently, reducing the risk of unexpected breakdowns that could lead to temperature inconsistencies.

This proactive approach not only extends the lifespan of the equipment but also reinforces the commitment to producing high-quality cider, showcasing the importance of meticulous oversight in every aspect of the cidermaking process.

Two Story Chimney Ciderworks’ cold room at its tasting room uses CoolBots on four seperate mini splits.

“The mini splits are residential A/C units and the CoolBots manipulate them to have them stay on longer and cool our space to 35 degrees,” explained Cidermaker Tommy Evans. “We found using regular Mitsubishi units the best.”

Evans added that they have a local HVAC company that can maintain and repair them if needed with even same-day service because parts are readily available, and they are much less expensive than commercial refrigeration both to buy and run.

For those in need of similar reliability, HVAC Minneapolis offers a wealth of expertise in maintaining and servicing systems efficiently. Local HVAC professionals in Minneapolis understand the unique climate challenges and are equipped to handle both routine maintenance and emergency repairs, ensuring that your system operates smoothly year-round. By choosing local services, you not only support your community but also enjoy the advantages of personalized and timely service.

Golden State Cider’s production process does not require a cold room, so they use commercial stand-up freezers and refrigerators to maintain temperature control for specific on-hand ingredients used in the cellar.

The apple juice used is pressed just days before and kept very cold in jacketed tanks until the need to ferment, explained Breanne Heuss, the company’s Director of Marketing.

The Golden State production team feels strongly that preventative maintenance is the best way to reduce downtime, potential product loss, and dollars spent.

“The team has an annual and quarterly punch list for our glycol chiller that is reviewed by our team with a vendor that specializes in that type of equipment,” Heuss said. “It is best practice to complete any major service in the spring, before the peak demand of the summer months.

“It is also recommended to regularly inspect the level and concentration in your glycol system, as well as the plumbing for any leaks.”

Fortunately, Heuss said, in the very rare case when they have faced a challenge with the glycol system or loss of power, it has not resulted in spoilage.

“We have had to postpone packaging,” Heuss said, “but the outage was not severe enough to have made an impact on the products.”
