I recently received the package and am using the large kettle for running a batch of mead. I washed the inside of the kettle, even though it looks completely clean, there could be oils associated with the fabrication process. It looks like the other included materials are well made and should work fine.The only negative is the thumper pot gasket is not permanently attached to the thumper lid. It appears that the silicon rubber gasket has shrunk and will need stretching to obtain an adequate seal.Please note that the kettle has a lid that is held down by clamps. if the vent line should plug, pressures could build inside the container. There is no pressure safety valve. It is your responsibility to make sure that there is a means for the kettle to vent vapors at all times as the kettle is not a pressure vessel.
