“great for dark lagers”

By: aryoung1980 | Date: May., 26th 2014 | Beer(s) Brewed: American Dark, Baltic Porter

I've brewed with this yeast twice and loved the results.

I made an American Dark Lager with a dry yeast and the WLP940. The one fermented with WLP940 really let the roasted malts shine. It took 1st place in a large competion for dark lagers. I will be rebrewing this summer for the MCAB XVII.

I also brewed a Baltic Porter for the afformentioned competition with a friend. We split a 10 gallon batch and pitched different yeasts. I went with the Mexican while he used the Zurich. The Mexican came out with dark fruit esters and was the better of the two batches. It took 3rd out of 24 Baltic Porter entries even though it was very young...8 weeks from grain to competition. It is even better now after proper lagering. I will be entering my final bottles into another competition to see how it compares.

If you want a malty lager, this is your yeast.

“WLP 940 Mexican Lager- Fantastic performance.”

By: TimBrewz | Date: Apr., 19th 2014 | Beer(s) Brewed: Mexican/American Premium Lager

I have brewed a few lagers per year for the last 8 years. Primarily I have used American Lager or Czech/Bohemian strains, making light lagers, schwarzbiers, doppelbocks and IPLs. Every time I made a lager there was either a lot of diacetyl, slow ferment, early flocculation or a long lagering phase to get the beer to finish properly. Anyway I just made a premium Mexican lager(1.050) with WLP940 and it was the easiest lager I have made to date. It acted much like an ale yeast: started right up (1.5 L oxygenated starter on stir plate) in 52 degree wort and finished out in a week(1.010). Did a D-rest for 2 days, crash chilled and kegged for lagering all within 2 weeks of brew day. The beer already tastes great, I can only imagine a month from now. I harvested a quart of yeast, and plan to brew many more beers with this yeast through the year. Highly recommended strain. Makes me want to brew lagers much more often!

“Crisp, clean, and easy to use”

By: Ben | Date: Jan., 20th 2014 | Beer(s) Brewed: Mexican Lager

Brewed a Mexican Lager a year ago with this yeast, and even though I'm still fairly new to brewing and didn't do everything "by the book", it took off just fine. The result was very clean, fairly crisp but not incredibly so. With a dash of lime it made my Cinco de Mayo party perfect. I've gotten more compliments on that beer than any other, and am now starting another, larger batch with the same strain.

“Super low fuss, hard working yeast.”

This was the yeast I tried for a German pils. It's not as crisp as WLP830, b
