WLP515 Antwerp Ale Yeast

Seasonal Availability: Nov - Dec

Clean, almost lager like Belgian type ale yeast. Good for Belgian type pales ales and amber ales, or with blends to combine with other Belgian type yeast strains. Biscuity, ale like aroma present. Hop flavors and bitterness are accentuated. Slight sulfur will be produced during fermentation, which can give the yeast a lager like flavor profile.

Great Yeast

By: Wes | Date: Aug., 26th 2015 | Beer(s) Brewed: Belgian Blonde

This yeast produces a very clean and restrained "belgian" character that I love. I've made 3 beers with it this year and this is now my go to Belgian strain. I'd love to see this yeast year round, it's a shame it's only a seasonal.

My Favorite Yeast

By: Sean W. | Date: Aug., 12th 2015 | Beer(s) Brewed: Blond, Dubbel, Belg. Pale Ale

After returning from a beer tour of Belgium in October last year, I was anxious to experiment with as many Belgian style yeasts as possible in hopes of re-creating some of the beers I really enjoyed over there. After experimenting with several strains including 500, 510, 530, 540 (and a couple strains from another yeast company ;) at varying temperatures, I concluded that WLP515 was consistently creating the types of beer I fell in love with while in Belgium.

I was happy to see this strain was available shortly after my trip, and to be honest was drawn to it partly by the name "Antwerp Ale Yeast" because I'd spent a couple days in Antwerp and enjoyed some really fantastic beers while in the Diamond District of that beautiful city.

Fermenting this yeast on the cool end of the spectrum (64-65F) in a pale beer together with the right amount of noble hops (this yeast pairs perfectly with Tettnanger), will resemble something close to a German Pils, with just a touch of esters and almost non-existent phenols. Fermenting on the higher end (70-71F) will, in my opinion, create the most amazing Belgian style blonds or dubbels you've ever had, producing a very subtle and balanced background of esters and phenols. Looking to brew a Belgian style Pale Ale? Ferment with this strain mid-range (67-68F) and you'll hit a home run.

After a dozen or so batches of Belgian style beers using varying Belgian style yeast strains, I presented my offerings for tasting to a local pro brewer who'd also been searching for a great Belgian strain. After sampling, he too concluded WLP515 was giving the type of flavor profile he was looking for and made this strain one of his house regulars.

I've been keeping a couple vials of this yeast going since December because I absolutely love every beer I've made with it. So... my goal is to spread the gospel of WLP515, and with any luck this strain will be promoted from seasonal to year round!

Antwerp Ale yeast is flat out awesome

By: brew monster | Date: Mar., 27th 2014 | Beer(s) Brewed: Belgian Blond and Belgian Pale ale

I've been making Belgian Pale ales for a few years now and had been using the Wyeast Schelde strain. It produces a really good product. This year they didn't produce it as one of their seasonal releases as they typically do. I knew that White Labs had their version but I had never thought about using it. I normally produce my BPA's in the late winter/early spring and keep enough to get me through the first month of Summer. I had my local HBS procure some Antwerp strian for me, 2 vials to be exact and I can honestly say that I will always use the Antwerp strain as long as White Labs keeps producing it.

I made an off-style,lighter version of a Belgian Blond first and harvested some slurry from that to produce 10 gallons of Belgian Pale ale. I used the other vial to make a clean starter to produce 10 more gallons of Belgian Pale ale(yes, I'm an overacheiver). The Blond was really nice and clean, crisp as I was hoping for. I got the same results with that slurry with the BPA and the same from the clean starter on the other 10 gal BPA batch.

Regardless of how you make your starter, which I always suggest, this yeast performed excellent for me for 2 Belgian styles. Fermentation range I used was wort chilled to 65 and free rise until it gets to 68-70. I held it there for 7 days. The blond finished in the single digits and I think that was due to the sugar addition in the boil. The BPA's were both consistent just above 1.010

Cleanest Belgian strain I've ever used and higly recommend giving it a try.

A local brewery brewed their Belgian Blonde using this yeast

By: Brewsed | Date: Jan., 11th 2013 | Beer(s) Brewed: Belgian Blonde

A local brewery brewed their Belgian Blonde using this yeast. This particular brewery is not know for consistently great beers, but the Belgian Blonde brewed with this yeast was amazing! Refreshing and crisp like a lager with subtle, yet apparent, Belgian character. The flavors/aromas contributed by the yeast paired quite well with a small late addition of CTZ hops. I missed the boat on my order, BUT WLP510 Bastogne is now available and in my fridge!

The yeast performed excellently

By: rjreusch | Date: Nov., 20th 2012 | Beer(s) Brewed: Belgium Pale Ale

I used this yeast to produce a Dekoninck-like ale. The malt bill was primarily pilsner and Vienna malts with some small additions of specialty malts for color adjustment and complexity. Since it is described as "lager-like" and I wanted some of the subtle fruitiness of the Dekoninck, I tried what I think is a similar fermentation regime used by the brewery. I started in the mid 60s but then allowed the temperature to climb during fermentation to the mid to upper 70s. I then allowed the temperature to drop back to 70 degrees where I maintained it until fermentation ceased. I was hoping to coax a bit more character while still maintaining a fairly clean end result. The yeast performed excellently. The copious amounts of sulfur produced during fermentation were not present in the final product. Some mild fruitiness from the yeast was evident along with a small amount of spiciness (probably the Saaz hops used). If you want a subtle Belgium Pale Ale and not the more extreme, estery results from some other Belgium yeasts then this is an excellent choice.

... truly delicious

By: Tony V. | Date: Nov., 20th 2012 | Beer(s) Brewed: IPA

I used this yeast to create two different batches of IPA that were truly delicious. Sulfur that is produced disappears completely leaving a clean balanced ale. The hops and the malt flavors meld together in harmony.

Fermentation proceeded excellently ...

By: pbutler | Date: Nov., 20th 2012 | Beer(s) Brewed: Belgian Ale

What a fantastic yeast! Fermentation proceeded excellently and was problem-free, despite a fairly strong wort (o.g. 1.065). The yeast is only a little bit fruity and has a wonderful rich flavor, producing a smooth creamy-textured ale. I made an ale in the style of De Konink but it would also be great for a Kolsch. I fermented it at temperatures in the lower end of the recommended temperature range, after aerating the wort well. I used a starter culture. I recommend this yeast for a variety of styles, it is well worth seeking out.

Can't wait to try to results!

By: Anonymous | Date: Nov., 20th 2012 | Beer(s) Brewed: Antwerp Abbey Ale

Fermented an all-grain batch with O.G. of 1.060 at 64-66F. Final result had a sharp, mildly unpleasant after-taste at 6 weeks that completely disappeared by 8 weeks, leaving a very tasty brew - wow! I'm looking forward to seeing how this one ages and definitely will use it again. In fact, I already have...I cultured it out of the dregs in two bottles, grew up a starter and pitched it on a tasty-sounding biscuit malt recipe. Can't wait to try the result!

... excellent choice

By: Jim Givens | Date: Nov., 20th 2012 | Beer(s) Brewed: Belgian Honey-wheat, Golden, Pale Ale

If Belgium could lay claim to a WLP001 California Ale type of yeast, WLP515 Antwerp Ale could possibly be it. It ferments out clean-like (as Belgian yeast goes) and it displays favoritism to hops – simply use less, if you prefer, and the malt balance is there. It does a very good job at making refreshing lighter beers and they tend to taste better fresh as opposed to modestly aged – you may notice some spice or citrus zest adjustment is necessary in the recipe as the beer mellows. WLP515 is fairly active in the first generation and it is a relatively fast ferment once it gets underway and in successive generations. It consistently has a rocky kraeusen even if fermented lower than the recommended temperature range. It will ferment quite successfully at 48-50 degrees F and is surprisingly active in this temperature range – most other ale yeasts would seem pretty sleepy – and it is even faster than many lager yeasts in this range. But for fermentation time versus flavor profile WLP515 really shines at about 65 degrees F or so – this gives the most flavor bang for the buck. If you want lots of earth or fruit or banana or bubble gun or spicy phenolic flavors in your beer then this yeast will disappoint you – it’s much too tame for that. But if you are looking for “training wheels” for your friends experiencing the Belgian yeast foray for the first time then this one is an excellent choice.
