Plastic lid for FE357A. Includes hole and grommet for airlock. Made from Polypropylene.
These buckets are made from polypropylene as it is less porous and significantly smoother than other HDPE fermenters. HDPE is porous and can harbor microbial activity making it more difficult to clean and sanitize.
Being less porous, polypropylene also does not absorb aroma like HDPE so there is less favour carry over from batch to batch.
