New yeast strain for sour beers

The yeast, colloquially called Philly Sour and now available for commercial and home sale, drastically reduces the time it takes to ferment a beer brewed to taste sour. Sour styles, which remain as popular as ever through the pandemic, can normally take months or years to fully mature as the usual wild yeast strains that lend their sour power slowly work to acidify the beer.
