![]() You would still need another means to cold crash, however. It won’t be ultra-efficient like a true glycol setup but it would be better than ice water. The solution won’t freeze in the freezer and will deliver colder liquid through your cooling coil-and most importantly the liquid will STAY cool. A 50-50 mix of glycol and water has a freezing point of -35☏. If you have an extra mini fridge with a freezer on hand you could drill holes in it for the tubing to pass through and create a closed-loop glycol system with a glycol reservoir inside. Other Ways to Keep The Water Supply Cold? Anvil makes a carboy version of the cooling system as well. 7 stopper so you will need a carboy with a no 7. Can I Use The Cooling System in A Glass Carboy? I would absolutely recommend this fermenter for anyone looking to get started with more control over their fermenting environment. Sure you can improvise with draping your fermenter with a cold or frozen towel or keep your fermenter in the bathtub but you certainly won’t get this level of automated control. Overall this setup is one of the more budget-friendly solutions to control fermentation temps precisely. You could absolutely push this fermenter colder into the 50’s assuming you keep replenishing the cold water supply. The newly supplied thermostat with the system also works just as well. I use an Inkbird digital temperature controller to easily ferment in the 64☏-68☏ range. The cooling system has been critical in maintaining my fermentation temps down to the degree. You will need to swap out fresh ice or ice packs daily to ensure your water supply remains cold. The water often returns to room temp every 6-8 hours and renders your cooling efforts useless. This is absolutely the most inefficient part of the entire process. ![]() You’ll need a cooler full of ice water as the water supply for the cooling system. Anvil fermenter with water supply below in cooler.If the temperature of the vessel raises even 1 degree (you can change the variance on the controller), it will activate the pump and cycle cold water (from a cooler) through the coils, bringing down the temp pretty quickly. You set your desired fermentation temp on the controller and plug the supplied pump into the controller. The digital thermometer probe fits into the thermowell and will give you a digital temp reading at the very center of the fermenter. Cooling System – 7.5 Gallon Bucket Fermentor The thermowell sits about halfway down the bucket and the coils reach a few inches from the bottom of the vessel. The coils and thermowell pass through the stopper and extend into the fermenter. The cooling system comes with a pump, neoprene jacket, Anvil temp controller, long stainless steel cooling coil, a thermowell, and a special no. You can also buy this fermenter in a smaller 4-gallon version as well. It’s worth noting that the Anvil fermenter and the cooling system are both sold separately. This is night and day over the standard bucket spigot. You can also adjust it to pull from any direction if you’d rather leave the last inch or so of beer in the fermenter. Lastly, the racking arm can be rotated by turning the outside spigot left or right. I found this handy for filling my hydrometer tube for gravity readings! No need to open the lid and expose your beer. The spigot is also really handy for quick samples or transfers to a keg without the need for an auto-siphon. ![]() The domed bottom is great for helping to separate the trub from the racking arm, giving you cleaner draining ability with less risk of clogging or transferring junk. I really like this feature as it is easy to pop open for any additions without shaking the entire fermenter. The fermenter lid clamps on with 4 clips ensuring a nice tight seal.
