Cooling Solutions For Kombucha, Cold Brew, And Specialty Beverage Production August 4, 2026 The specialty beverage category has expanded significantly — kombucha, cold brew coffee, kefir, jun, water kefir, and various functional fermented drinks each have distinct cooling requirements tied to their production biology. Commercial-scale production of any of these products requires mechanical cooling systems that understand the specific temperature demands of live cultures and cold-process beverages. Kombucha Production Cooling Commercial kombucha production involves temperature control at multiple stages: Fermentation (SCOBY culture): active kombucha fermentation targets 75-80 degrees F for typical continuous or batch-fed culture. This is warmer than beer fermentation and may not require active chilling in temperate climates, but summer ambient conditions can push fermentation above optimal temperature, requiring cooling capability. Secondary fermentation (carbonation): after bottling, secondary fermentation in refrigerated or temperature-controlled conditions targets controlled CO2 development. Temperature directly affects carbonation rate and final product character. Cold storage and distribution: finished kombucha is a live culture product — temperature must be maintained through distribution to control ongoing fermentation and CO2 buildup in packaged product. Cold Brew Coffee Cooling Requirements Cold brew coffee production has straightforward but critical temperature requirements: Steep temperature: commercial cold brew is steeped at 35-40 degrees F (refrigerator temperature) for 12-24 hours, or at room temperature for 4-8 hours with subsequent cold crashing. The cold-steep method produces a cleaner, less acidic product. Filtration and packaging: must occur at cold temperatures to prevent accelerated oxidation and microbial growth in the finished product Cold storage: finished cold brew is highly sensitive to temperature abuse; distribution chain temperature control is as important as production cooling Product Critical Temperature Points Kombucha 75-80 degrees F fermentation; 35-40 degrees F cold storage and distribution Cold brew coffee 35-40 degrees F steep; 35 degrees F storage Water kefir 70-75 degrees F fermentation; below 40 degrees F finished product Jun (honey-green tea) 75-80 degrees F fermentation; cold storage below 40 degrees F Drinking vinegar / shrubs 60-75 degrees F fermentation; ambient storage acceptable for shelf-stable formulas "Specialty beverage producers often underinvest in cooling early on and create problems they have to solve at scale. Live-culture products especially need consistent temperature from fermentation through distribution."— Andy Backer, VP of North American Sales, G&D Chillers Sizing Cooling for Specialty Beverage Operations Unlike beer or wine, many specialty beverage operations have fermentation at near-ambient temperatures and their largest cooling load is cold storage and distribution staging. Key sizing considerations: How much product needs to be held at cold temperatures at any given time? What is the throughput of product moving from fermentation to cold storage daily? Does your production building maintain adequate fermentation temperatures year-round without active cooling? Are you co-packing or using shared cold storage facilities? If not, your cold storage capacity is entirely on your own infrastructure. Frequently Asked Questions Can I use a standard commercial refrigeration system for specialty beverage production? For modest scale, yes — commercial walk-in coolers and glycol systems serve many specialty beverage producers well. At larger scale (above 500-1,000 gallons per day), purpose-designed chilled water or glycol systems with dedicated chillers provide better capacity, control, and efficiency than residential or light-commercial equipment. Does live-culture beverage production have specific food safety cooling requirements? Yes. FDA food safety requirements (under FSMA for commercial food and beverage operations) require temperature monitoring and control documentation. Fermentation temperatures, cold storage temperatures, and distribution temperatures must be monitored, recorded, and maintained within validated ranges. A reliable mechanical cooling system with monitoring capability is required, not optional. > Talk with G&D's team about cooling for specialty beverage production at commercial scale -> Contact us
