WLP600 Kombucha SCOBY

White Labs now offers WLP600 Kombucha SCOBY, a symbiotic culture of bacteria and yeast that is used for fermenting sweet tea into kombucha. White Labs’ SCOBY is free of food pathogens and has been genetically identified to know specially what yeast and bacteria are involved in the fermentation of kombucha. As we continue our genetic identification we will publish the data on this page. This SCOBY has medium acetic acid production and low alcohol production based on our recipe. The SCOBY diameter is 2.92 inches.

What is in the White Labs SCOBY?

How much will one SCOBY make?

One SCOBY will make 1 to 5 gallons of kombucha however, the White Labs SCOBY only contains enough starter liquid for 1 gallon of kombucha. If more than 1 gallon of kombucha is being produced you will need more starter liquid. Previously made kombucha or store bought plain kombucha works as starter liquid.

Can I reuse the SCOBY?

Yes, you can reuse the SCOBY as long as it is taken care of and stored properly. A new SCOBY will be produced with every batch of kombucha made, you may use this newly produced SCOBY for future batches as well.

How do I properly store a SCOBY for future use?

For short term storage, a clean, food grade container placed somewhere out of direct sunlight and left undisturbed is suggested. If you will not be using your SCOBY for an extended period of time, place it in a clean, food grade container in the refrigerator for up to 3 months. Feeding (adding new tea) as needed to keep the SCOBY from drying out.

Does the SCOBY need to be refrigerated?

It is recommend that you refrigerate the SCOBY until you are ready to use it. Let it warm to room temperature before use.

When is the SCOBY expiration date?

Is this an ale or a lager culture?
Is this an ale or a lager culture?

WLP611 is an ale culture derived from saccharomyces cerevisiae. This blend ferments as low as 50°F (10°C) and up to 86°F (30°C) and is because of this wide range spanning all the way from neutral and clean aromas to spicy and fruity.

WLP095 Burlington Ale Yeast

This yeast has proven to be great in IPAs. This is a great yeast for people who like WLP001 California Ale Yeast because this yeast throws a little personality and body into your beer. Esters are higher than WLP001. This yeast has been known to result in more diacetyl so increasing the temperature at the end of fermentation is suggested.
