This bucket is great as a primary fermenter for wine, cider, beer, etc.

The lid fits loosely over the top to keep things out, while allowing Co2 to escape.  

When fermenting grapes with skins in this fermenter, it is capable of holding just over 75 lbs of grapes, with room for the cap to rise during fermentation.   100 lbs would be too much and the cap would rise over the top.
