TheFerMonster Wide-Mouth Carboyis here! Unlike other standard and wide-mouth carboys in the market, theFerMonsterfeatures smooth, ribless sides. This helps to reduce the residual yeast and sediment build-up, making cleaning simple. A 4" wide-mouth opening reduces spillage and the need for additional equipment when filling or cleaning theFerMonster. Other features include:
Large enough capacity to be used as a primary or secondary fermenter
Brilliantly clear with built-in 5, 6 and 7* gallon markings (*7 gallon marking will only appear on the 7 gallon version)
Made with food-grade plastic and BPA-free
Lid is constructed as one piece, providing an airtight seal
