** COMING SOON **

This kombucha SCOBY has been used by White Labs and tested for over a year at our facilities. Low acetic acid production and low alcohol production is based on our recipe. Below are organisms that were isolated from the SCOBY. More organisms are likely part of the SCOBY, but have not yet been culturable for isolation. For a Kombucha recipe, check back soon for an update to this page. Product is large enough to start 1 to 3 gallons but will grow over time to accommodate larger sizes.

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.

Update 2

By: Ian | Date: Sep., 10th 2015 | Beer(s) Brewed: Witbier

Weeks 6-8 it changed from the initial apricots/mustiness into skittles/mustiness. Three months later it is becoming less skittles are more musty.

Update

By: Ian | Date: Aug., 18th 2015 | Beer(s) Brewed: Witbier

Ended up with a pH of 4. Not sure how that happened, but it was not infected due to my brewing...

The citra dry hopped witbier ended up with apricot and musty notes to it in the finish. The hops complimented it perfectly. WLP648 would be a good addition to a biere de garde or a fruit beer with apricots or peaches.

Ferment it hot

By: Ian | Date: Jun., 27th 2015 | Beer(s) Brewed: Witbier

I loved brewing with WLP 644 and often fermented in the the lower end of the recommended range of 70-85 F at home.

WLP 648 has the same optimum fermentation range but I have only noticed active pellicle formation and other activity near 80 F. If you are a home brewer without temperature control, this may not be the best option for using during cooler months. Instead, I would probably use WLP 644 due to its greater activity at room temperature.

Vigorous yeast!

By: Pkingduck | Date: Oct., 5th 2015 | Beer(s) Brewed:

I tried this with my Apple saison recipe that used Wlp 565 last year. Very impressive attenuation, fermenting down to 1.001 within 2 weeks. May have had the fermentation temp a little high at 85, but wanted to push it like other saison yeasts. Definitely got a "bite" to it, but overall pretty clean.

Sour Beer 100% Brett Fermentation

By: Scott | Date: Feb., 8th 2016 | Beer(s) Brewed: American Sour

We brewed a 100% Brett sour beer with WLP645 Brett C and WLP661 Pedio following the Rare Barrel method. I made a 3-stage starter with the Brett in order to get up to typical sacc pitching rates and also made a starter with the pedio. We pitched both starters directly into the primary (no sacc or lacto), racked into a 5-gal glass carboy after a two-week primary, and aged for a year. The SG was 1.050 and FG 1.005. The beer turned out surprisingly clean tasting. The Brett C did a good job cleaning up any diacetyl that the Pedio created during its fermentation. There is a slight Belgiany-type yeast flavor from the Brett C, but no “funk”. The pedio gave the beer a mild lactic sourness, the deep and complex type of sour that is felt on the back edges of the tongue. I would classify the intensity of sourness as low-medium. It took the Pedio about 6 months before any sourness could be detected on the palate. I actually wish that the final beer was a bit more sour. We also split the batch and aged portions of it on fruit, which turned out delicious.
