Philly Sour Yeast was a great alternative to kettle souring that didn't require tying up my brewhouse for multiple days or the hassle of dealing with infectious bacteria in the brewery. I also loved the fruit esters that give the final products a bit more character than your traditional kettle sour method.
Philly Sour has given us a way to brew sour beers with a relatively quick turnaround without tying up our brewhouse for kettle sours. We’ve been able to maintain our normal schedule while this unique yeast produces both lactic acid and alcoholic fermentation in a reliable manner only 4 to 5 days longer than a typical ale. We’ve found it produces really nice and clean sour ales and works well with a number of different fruits. While we’re still learning about the yeast, we put it into full production almost immediately and have had great results.
