WLP029 German Ale/ Kölsch Yeast

From a small brewpub in Cologne, Germany, this yeast works great in Kölsch and Alt style beers. Good for light beers like blond and honey. Accentuates hop flavors, similar to WLP001. The slight sulfur produced during fermentation will disappear with age and leave a super clean, lager like ale.

Great yeast for a Kolsch, American Pale Ale, or American India Pale Ale

By: Sean | Date: May., 23rd 2016 | Beer(s) Brewed: Kolsch, APA, IPA

This yeast is a favorite of mine. Not only does it make a very delicate Kolsch with accentuated hop bitterness. It really shines and makes great American Pales and IPAs, too. One of my favorite things is the yeast flocculates very well when the beer has fully attenuated so it's easy to make a beer of great clarity if you don't have a lot of dry hops in the fermenation vessel. These yeastie boys also get moving quickly. I've never had a lag greater than 4 hours with a fresh starter.

Perfect Yeast for a Variety of Brews

By: Uncle Pauli | Date: Mar., 22nd 2014 | Beer(s) Brewed: Kolsch, Helles, Maibock, Noche Buena clone, Oud Bruin

I first used this with an Austin Homebrewing Texas Kolsch kit (which is my "house light"). Since I'm not equipt to lager, I've used this strain for Helles/Maibock, Octoberfest, and a Mexican Christmas (Noche Buena) clone. I've even used it as a starter for a Flemish Oud Bruin, added the "funk" after 1 week in primary. I guess you could say this is my "go to" yeast strain.

If you need a clean, clear yeast which accentuates your hop profile, or want to brew lager recipes at ale temperatures, this is the one for you!

As mentioned, it will start out vigorously and after a few days in primary, give off a nasty, sulfur smell...don't freak out...that will all clear up in the secondary and you'll be very happy with the results.

Incredibly interesting flavor profile

By: Aydin Manouchehri | Date: Dec., 18th 2013 | Beer(s) Brewed: Koelsch

Fermented an all Pilsner malt koelsh with this yeast. The result was a fascinating flavor. It really does taste like a hybrid between a lager and an ale. You get fruity undertones, reminiscent of apple and white grape, but finishes with that clean lager character with no phenolic or fussel bite. I am very intrigued, and will use again. Highly recommended for a a low IBU, low gravity, light color beer that my wife certainly appreciates.

Should I wait after bottling and before lagering a Kolsch?

By: Ricardo Golcalves | Date: Jun., 18th 2013 | Beer(s) Brewed: Kolsch

Hi there,
This is my first Kolsch beer and I've seen many people recommending that a couple of weeks of lagering would improve the beer. White Labs says that the WLP029 yeast does not ferment under 17C so my question is: if I bottle it and transfer to a fridge straight away, will it get any carbonation? How can the corn sugar added ferment inside the bottle if the temperature is well below 17C in the fridge?
Many thanks

This was our second batch of "Straw Dog Kolsch"

By: Rick morris | Date: Nov., 6th 2012 | Beer(s) Brewed: Kolsch

This was our second batch of "Straw Dog Kolsch", as we call it (http://howbrewbeer.com/brewbeer-strawdogkolsch.htm At day 2 of fermentation, we noticed the sulfur/rotten egg smell coming from the carboy air-lock. we also noticed the slight darkening coloration of the foam head (almost like merangue being browned on a pie in the oven). After some research, we have determined that this is normal for this type of yeast. Oddly, we didn't observe this with our initial batch several months ago. As we always smell the escaping gas, we knew immediately something was up with this batch. That's what sent us searching for answers. Everything was meticuously sanitized, so we know there isn't bacteria infecting the brew.

I pitche the vile into 5 gallons of 1.042 California Common wort

By: Knox | Date: Nov., 4th 2012 | Beer(s) Brewed: Common beer, strong ale

I pitche the vile into 5 gallons of 1.042 California Common wort and after 5 weeks in primary and 1 week in the bottle it was perfect. Very clean and great malt/hop profile. I pitched the subsiquent cake into a maple brown strong ale at 1.090 o.g. wort and it took it down to 1.018(80%aa). Both beers were very clean. I will definatly use this yeast for any suedo lager needs in the future.

I used this yeast in August

By: Paul Butler | Date: Sep., 12th 2012 | Beer(s) Brewed: Pale Ale

I used this yeast in August. 2012 to brew a traditional pale ale. The yeast was very well behaved, the fermentation was aggressive and I can already tell that the beer will be excellent. Average temperatures for my fermentation were around 68 degrees but with significant temperature fluctuations that didn't bother the yeast at all. The beer is now in secondary but is almost completely fermented. An excellent yeast to try with any ale,! highly recommended. Imparts a balanced, clean flavor.

This has become my favorite yeast

By: Mark Bauer | Date: Aug., 13th 2012 | Beer(s) Brewed: Kolsch, Alt, Cream Ale, Amber

This has become my favorite yeast. It is perfect for a number of styles with a delicate fermentation profile. I started with a Kolsch an expanded to a number of differnt styles and experimental brews. If I could only have one yeast, I would go with this.

I pitched one vial into a 1.042 O.G. California common with excellent results

By: KnoxTennessee | Date: Jul., 8th 2012 | Beer(s) Brewed: California Common, Imperial Maple Brown

I pitched one vial into a 1.042 O.G. California common with excellent results. After four weeks in the primary and one in the bottle it was delightful. Full and malty with a great dry bitter finish from the Northern Brewer hops. Very clean and lager like, albeit with some nice apricot esters. Even though it finished a little high (1.012) the beer is still nice and dry. I wanted to see what this y! east was capable of so I brewed a 1.090 O.G. maple brown with 10# of LME, .5# of chocolate malt, and a quart of maple syrup. I dumped it on the yeast cake and in 5 weeks it's down to 1.018. The finishing hops in both beers are coming through nicely.

... I nicknamed it ...

By: Grande Dave | Date: Feb., 6th 2012 | Beer(s) Brewed: Blonde

I LOVE THIS YEAST! Best beer ever! I'm new to home brewing and was very nervous when I first used this yeast. I fermented like crazy and didn't smell great. In fact, I nicknamed it "arse yeast" and that's what my home brew shop now calls it. BUT after fermentation was done, the beer was incredible! It tasted great right off the yeast cake and even better once carbed in chilled. I'm brewing another batch now. I did a starter with this one and it actually smells good fermenting.....bread like...

WLP029 vs. WLP036

By: Schuyler Campbell | Date: Jul., 11th 2011 | Beer(s) Brewed: Düsseldorf Altbier

WLP029 flocs out somewhat more easily than WLP036 and ferments better a bit warmer. Where I like WLP036 fermenting around 52F, WLP029 has given me great results at 57F. WLP029 will make a great Altbier and is the preferred yeast for Kölsch. WLP036 is excellent for Altbier, but lacking the character WLP029 provides to the more delicate Kölsch style. As always, with a cooler fermentation, you need to pitch much more yeast, so I always make a big starter when brewing up a German-style ale. WLP029 and WLP036 are excellent yeast choices for cold-fermented ales, but I would not use either German ale yeast if you do not have adequate fermentation temperature control, as they are known to be a lot more testy than the very-similar WLP001. If you want to brew a Kölsch or Alt and you are fermenting at or around room temperature, do yourself a favor and use WLP001 instead. (Note: this review also appears on the WLP036 page).

.... the beer clarified quickly

By: BrightSpotBrewing | Date: Jun., 17th 2011 | Beer(s) Brewed: Northern German Alt, Brown Ale

This might end up being a go to for us. Great malt profile, hops are certainly accentuated but not too much, and the beer clarified quickly. Used a 1.5L starter for 5.5 gal batch, which worked great! I highly recommend this yeast.

.... one other requirement is 'no diacetyl

By: Ken | Date: Apr., 10th 2011 | Beer(s) Brewed: Pale Ale

I am entering this beer in the Olde Mecklenburg Brewery's Rein Stein Pale Ale competition. This is all grain with an OG of 1.056. The competition requires this yeast and one other requirement is "no diacetyl". I brewed yesterday, pitched two vials (no starter) and it is now fermenting at 64 degrees. How long do you recommend keeping it in the primary? Do you recommend a lagering period and if so at what temperature? Thanks. Looking forward to the end product regardless of competition results.

WLP029 or WLP036?

By: RCA | Date: Mar., 7th 2011 | Beer(s) Brewed: Alt

I brewed a traditional Dusseldorf Alt a few months ago with the WLP036 and it turned out fantastic. However, I'm thinking of doing another Alt with a N. American spin (mix of Noble and higher alpha-acid American hops) to try and produce something like Ninkasi's Sleigh'r. Not sure if I want to use the WLP036 again or give the WLP029 a try. What differences can I expect if I were to use the WLP029? (Note: this review also appears on the WLP036 page).

It's very clean

By: Jason Lewis | Date: Jul., 6th 2010 | Beer(s) Brewed: Kolsch; Lemon Weiss

I brewed a Kolsch with this yeast and my friend brewed a lemon weiss. We fermented at around 62 degrees. We then lagered at around 48-50 degrees for 3 weeks. The kolsch is outstanding. It's very clean. There are a little bit of fruity undertones, sort of like a white wine with a tiny bit of apple. It's very minimal though and just adds a complexity to the beer. Overall, the yeast is cleaner than some commercial Kolschs that I've drank. This yeast does not finish as dry as some other commercial kolschs that I've had either. I like that it's so light and has some residual sweetness. I could see using this beer in a cream ale for superb results.

... massive hop aroma ...

By: j_snook | Date: May., 19th 2010 | Beer(s) Brewed: American IPA

Already reviewed this strain for Kölsch. Used it recently in an IPA and it was fantastic. Made an American IPA on a grist of 2-row, crystal and Munich malts and lots of high-alpha American hops. The resulting beer has massive hop aroma from the late additions, as well as pronounced bitterness. Finish is crisp. Attenuation was excellent as always with this strain. Someone asked below in a review how this would work for IPA which gave me the idea to try this, and I would say this strain is just as good a choice as 001 when you want a clean flavor profile and to highlight hops. Very versatile strain since you can also use it to focus on the malts in styles like Kolsch. Very little yeast-derived flavor in the IPA fermented at 67dF.

... will be adding this to my arsenal

By: tranehead | Date: Mar., 30th 2010 | Beer(s) Brewed: Kolsch

I made an American Wheat beer as a starter for this yeast. I wanted a big yeast cake to pitch onto for my Kölsch. The wheat beer came out great, especially given it was all extract. The Kölsch finished fairly quickly (5-7 days) with the big yeast cake to pitch onto. I GOT 81% Attenuation. crazy yeast. 1.054, a little big for Kölsch, yes, but it was more efficient than expected. Making braggot with leftovers. This is a GREAT yeast and very forgiving temp wise. Collected slurry and will be adding this to my arsenal!!!

This produces a very nice Kolsch

By: d_h | Date: Apr., 29th 2009 | Beer(s) Brewed: Kolsch

Making a nice, big starter I have had very good luck pitching and fermenting around 60F. This produces a very nice Kolsch. Very lager like in the fermentation profile.

Frequently Asked Questions

I wonder if you could help me with my Kolsch. I'm looking to brew this as my next batch (40L). I notice from your information about WLP029 that it shouldn't be fermented at any less than 62F, which according to my calculations is 16.7C. What is your advice here?

For WLP029, people can experience problems under 16C, so we recommend that temperature, but many do ferment cooler. You just have to be more careful and keep an eye on the fermentation. With 029, you don’t need to ferment that cool anyway to get the clean flavors, you can cool it during fermentation if you like, but I wouldn’t the first time and see what you think.




Optimum Ferment Temp.65-69°F, 18-20°C (Does not ferment well less than 62°F, or 16°C, unless during active fermentation)
