Abstract: | Summary Thirty-four wines that showed problems during malolactic fermentation were obtained from five different German wineries and were examined for the presence of phages using electron microscopy and the agar spot-test. Phages were discovered in 11 of the wines and host strains were found for ten of these phages. The phages were characterized on the basis of their morphology, host range and protein profiles. Furthermore the ten phages could be divided into four groups by restriction enzyme analysis of the phage DNA. This grouping was consistent with results based on morphology, protein composition and host range analysis.
