''Pediococcus'' may also cause “ropiness” (also called a "sick beer") due to the production of exopolysaccharides. "Ropy" or "sick" beer is more viscous and, in extreme circumstances, can form strands. Sickness effects mostly the mouthfeel and appearance of beer, and may have no influence on the flavor. ''Pediococcus'' species can also produce diacetyl with extended storage time. [[Brettanomyces]] can break down exopolysaccharides and diacetyl produced by ''Pediococcus'' and the two are often used together.
