Fermonster - The World's Biggest Wide-mouth Carboy

Effortless Cleaning: The wide 4" mouth lets you reach right in to tackle those dirty shoulders and edges. Plus, the smooth, rib-less sides minimize residual yeast build-up for easier cleaning and racking.

Maximize Your Yield: The cleverly indented bottom allows you to extract more liquid and less sediment when racking. Crystal-clear construction with volume markers ensures accurate measurements every time.

Safe & Secure: Made from 100% food-grade BPA-free plastic, this fermenter is built to last. Note: When using hot water, do not exceed 52° Celsius.
