More hop tolerant than other Lacto strains, however TYB advises to use wort with less than 10 IBU. White Labs data sheet shows that growth is inhibited to 82% at 5 IBU, and 60% at 10 IBU <ref name="WL_datasheet" />.

This strain can take several days to acidify unhopped wort, and as such is not recommended for kettle sours. This strain benefits from magnesium nutrient additions, and is slightly inhibited by zinc nutrient additions <ref>[https://www.mdpi.com/2218-273X/10/12/1599 Chemical Composition of Sour Beer Resulting from Supplementation the Fermentation Medium with Magnesium and Zinc Ions.
