Lallemand Philly Sour Yeast 11g

WILDBREW PHILLY SOUR™

WildBrew Philly Sour™ is a unique species of Lachancea selected from nature by University of the Sciences in Philadelphia, PA, USA.

(Patent pending N° PCT/US20 18/043 148). WildBrew™

Philly Sour produces moderate amounts of lactic acid in addition to ethanol in one simple fermentation step. This first yeast in the WildBrew® series is a great choice for innovative, sessionable sour beers with refreshing acidity and notes of stone fruit. With high attenuation, high flocculation and good head retention, WildBrew Philly Sour™ is an ideal yeast for traditional styles such as Berliner Weiss, Gose, American Lambic Style, American Wild Ales and its resistance to hops make it perfect for Sour IPA’s.


Recommended Fermenter

Research has shown that in order to extract the most flavour from hops and yeast, and to minimise contact with oxygen, pressure fermenters are the best fermenters for any style of beer which is why the manufacturer recommends to use one of the below fermenters:

Dry Yeast Frequently Asked Questions

Below you will find the questions we get asked the most regarding our dry yeasts.
Please click on one of the questions below to see the answer.

Dry Yeast Usage

Is it recommended to rehydrate dry yeast?

A big part of homebrewing comes down to what works best for you and also following producers' recommendations. We would encourage you to read instructions before use.

Do I need to rehydrate the yeast before pitching?

Typically, dry yeasts do not need to be rehydrated before use and can be pitched directly into our fermenters. However, some brewers prefer to rehydrate dry yeasts as they think it speeds up the start of fermentation.

How do I rehydrate dry yeast?

To rehydrate yeast, simply add around 300ml of lukewarm water to a sanitised conatainer, and add the content of the packet then cover with a layer of tin foil. You will notice that after an hour or so, the yeast will start to buble and activate.

Storage Recommendation

How do I store my dry yeast?

Store in the fridge or dry and cool place.

How long can I store my dry yeast for?

Dry yeast can be stored for extended periods of time. Please refer to the package for the best before date.
