Characterized by a malty finish and balanced aroma. It is a strong fermenter, produces slight sulfur, and low diacetyl. It can produce some fantastically complex, malty beers but it is a little bit more unpredictable than WLP830.

We Recommend you make a yeast starter for all lagers. Because of the cold environment you will need about 4 times as much yeast to successfully ferment a lager. If you don't have a yeast starter pitch 2-4 vials at 60-70F and cool to 48-52F within 12-18 hours. To ferment lagers like the German's and Czech's make an active starter of 2000ml per 5 gallons. Pitch at 45-48F and let it naturally rise to 48-52F. Hold your fermentation at 48-52F for 4-6 weeks in the primary. A diacetyl rest is recommended after the last week of fermentation. Raise to 55-58F for 3-5days and crash to 40F. It is normal if lager fermentation takes 3-4 days to show any sign of krausen after pitching yeast.

Attenuation: 68-76%
Flocculation: Medium to High
Optimum Fermentation Temp: 50-55F
Wyeast Equivalent: 2308 German Lager

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

Seemed like a good fit for the Helles. Looking for more variety than what I get from dry yeast.
Robin Krause on Jan 10, 2021
suggested yeast for munich helles from youtube channel mean brewer. like purepitch better because the age of yeast is not affected as much with the viability.

behold the malt
Really brings out the malt flavors in my Helles. Very clean yeast, no diacetyl with a 2 day rest, very clear. Will be using again.

This is my go to lager yeast. I use it in my Munich helles and Vienna lager recipes. 2 day diacetyl rest two gravity points from fg and then your good. Ferments well at 51 degrees. I lager for 30 days and have not been disappointed in any of the beers I have made. Love the Southern German lager.

What can you say? It's from White Labs...
White Labs is my go to yeast supplier. Given that I live in MA, I highly recommend getting a cold pack and making a starter once if you live outside of CA.
