A filter candle for a precoated filter for filtering and/or stabilizing fluids, especially beer, the filter candle comprising a tubular filter body that is formed from a spirally wound wire, with gaps being provided between the wire windings as fluid passages. To improve the adhesion of the precoated filter in such a filter candle, the surface of the wound wire that rests against the exterior of the filter body is inclined by an angle &#x3b1; relative to the longitudinal axis of the filter candle.

The present invention relates to a brewing vessel comprising a manhole opening which is closable by a lockable lid. To obtain a simple locking mechanism which, in particular, does not create any unaccessible space, the locking ring is supported on the outside of the frame and comprises at least one locking bolt which cooperates with a recess formed in a collar of the lid.
