''Lactobacillus plantarum'' has been found to produce 3-sulfanylhexan-1-ol (3SH) from precursors in wine (3SH-S-cys and 3SH-S-cysgly) at a more efficient rate than wine yeast. 3SH is a volatile thiol that has a grapefruit-like flavor and aroma and is considered to be an important flavor component of some wines <ref>[http://sci-hub.hk/https://www.sciencedirect.com/science/article/pii/S0308814618305594 Impact of Lactobacillus plantarum on thiol precursor biotransformation leading to production of 3-sulfanylhexan-1-ol.
