Most of the drums and tanks that we offer are consider food grade and so they are considered safe for contact with food and beverages. As far as this aspect of the application they are acceptable. However, we are not familiar with what other requirements the drums and tanks would need to meet and therefore are not able to expressly recommend them for the purpose of fermenting. It is up to the end user to determine suitability of a vessel for their particular application.
Typically we have noticed most customers use our closed head drums and inductor come bottom tanks. Closed head drums are able to be completely sealed when the bung plugs are screwed in tight and the inductor cone bottom tanks come with non-vented screw in lids. The closed head drums are typically used for liquids since they have only small bung holes in the top for access to the inside. The tanks are a better choice for things that contain solids because of the wider openings at the top. Another beneficial feature for the inductor cone bottom tanks is the ability to draw off through the fitting in the bottom of the cone and the ability to add additional fittings to the top or side walls.
Open head drums would not be recommended since the lids are not designed to hold liquids and they do not seal air tight.
What we would ask that you keep in mind is the fact that these are plastic and while food grade, we do not guarantee that they will not impart a plastic flavor to what is being stored inside. If you do notice a smell or flavor, one thing that may help is to rinse the vessel with a bleach solution followed by thoroughly rinsing with water.
