Flexible Packaging Integration: Equipped with a sanitary 1.5" butterfly valve for seamless, low-oxygen closed transfers directly into kegs, bottles, or canning lines. Commercial cold brew production has traditionally been a messy, backbreaking process. Hoisting 40 pounds of soaking-wet coffee grounds straight up out of a flat-bottom plastic bucket is a workplace hazard waiting to happen. To make matters worse, struggling with cloudy sediment leads to clogged draft lines, chalky mouthfeel, and drastically shortened product shelf life. The BrewBuilt® CB1 completely redefines small-scale commercial cold brew production. Built on our heavy-duty, 304 stainless steel bottom-drain chassis, this turnkey system eliminates overhead lifting, guarantees brilliant liquid clarity, and adapts to any packaging workflow. Whether you run a bustling cafe, a roasting facility, or a craft brewery, the CB1 delivers a high-yield solution designed to protect both your back and your brew. Key Design Innovations Ergonomic Side-Manway Cleanout The CB1 features an integrated, rectangular side-manway door. Instead of lifting heavy, dripping bags up and out of the vessel, operators simply open the front door and easily slide or rake spent coffee grounds out horizontally into a waste bin. Progressive Dual-Stage Filtration Achieve unmatched clarity without the need for expensive secondary paper filters. The CB1 utilizes a stacked filtration system featuring a Fine mesh bag nested inside an X-Fine mesh bag. Heavy-Duty Drawstrings: Both commercial-grade bags feature rugged drawstrings that cinch tightly around the rim of the kettle, keeping them securely locked in place during the steep. The Slotted False Bottom Advantage: As seen in the cross-section view, the nested bags rest completely flat on a heavy-gauge, slotted stainless steel false bottom. This structural support keeps the fabric elevated above the true dished bottom, preventing the weight of the coffee grounds from plugging the drain hole and ensuring an unrestricted, rapid extract flow. Total Packaging Flexibility The sanitary 1.5" Tri-Clamp bottom butterfly valve acts as a modular launchpad for your finished product. Once the steep is complete, you can gravity-drain the kettle with precision control: Kegging: Perform flawless, low-oxygen closed transfers directly into purged beverage kegs. Bottling & Canning: Hook up directly to counter-pressure bottle fillers, BeerGuns, or small-scale canning lines.
