I had an inkling to try

By: Daniel | Date: Jul., 4th 2012 | Beer(s) Brewed: Experimental/Maibock-type ale

I had an inkling to try and create an ale that was similar in taste and aroma as a Maibock lager...   but without using any colder fermentation or pseudo-lager techniques. This yeast was the last   missing piece I needed. Definitely should be a year-round strain. It fermented perfectly at 70deg F.   No off-flavors or diacetyl. Also flocculated very well, leaving a nice clear beer. Left me with a   finished product that had a nice, clean malty aroma, very pleasant malt taste, and little in the   ways of "ale-iness" overall. Great great yeast indeed!!

Worked well

By: Marc | Date: Jun., 11th 2011 | Beer(s) Brewed: Coopers original pale ale extract kit

It had been suggested that I not use the dry yeast that comes with the kit so I ordered WLP009 from Northern Brewer. Worked well, my only drinks the Cooper opa from the store and she liked what I brewed, success......

Nice strain

By: Jonathan Avedian | Date: Jan., 17th 2011 | Beer(s) Brewed: Porter, Red Ale

This was much more attenuative than I anticipated. Ferments quick, and did not produce much krausen - I had to take gravity readings to make sure it was working. Nice subtle ester profile, bready. Nice strain. One down side is it does not create a tight sediment - be careful racking or you will suck up yeast.

produces a clear beer with a nice malty finish

By: rudrasarrow | Date: Sep., 29th 2008 | Beer(s) Brewed: Extra Special Bitter

Just as described this yeast produces a clean beer with a nice malty finish. I made a pretty traditional English bitter and the hops do come through but I did not go crazy with hops and used traditional English hops. With this in mind it produced a fine beer. I fermented around 65 degrees and the beer has a crisp bitterness almost lager-like. If I let the beer warm up though the malt flavors begin to dominate a bit more. This yeast could probably make a nice porter or stout too. Great strain and I look forward to trying some other styles with it.

Fermentations start frighteningly quickly ...

By: Scott Walters | Date: Oct., 15th 2007 | Beer(s) Brewed: IPA

Started using this, on the recommendation of the local brew supply store, for the warm months here in Arizona where the only place in the house at 78 degrees was the few feet of hall in front of the thermostat, but it became the key component of our signature ale. Fermentations start frighteningly quickly and go aggressively but seems to take extra long to settle out.
After 10 days in the bottle, it mellows out. It's as good warm as cold. It's strongly flavored without being conspicuous (like an English ale or anything Flemish). It's most recognizably beer but it's chewy and malty rather than "clean". Drinking ale made with this yeast, you might wonder when it's from rather than where. I imagine it to taste like beer before it was heavily refined... even more like "pirate ale" than most homebrew, and it tastes that much less like what usually comes in a can.
I adore this yeast. When White Labs stopped stocking it, I spent days calling and searching before I tracked down nfghomebrew.com, who stocks it year-round. They half-joked, "White Labs makes it just for us". The reception to it in a pale ale from casual beer drinkers is always interesting, too -- it has a charisma where people who don't like anything but the blandest American lagers will sip it with interest. It's that likeability that really cemented it as our signature yeast -- it just became known as "that beer you guys brew" by our non-homebrewing friends as they asked for more.
(Editors Note: Any store can stock out-of-season platinum strains or discontinued strains if they order a minimum of 40 vials.)

Truly a yeast worth trying ...

By: Tony V. | Date: Jun., 11th 2007 | Beer(s) Brewed: Dry Irish Stout

This yeast has a soft bready character that is quite pleasant in beers with toasted or strong roasty flavors. It flocs out well and finished fermentation quickly. Truly a yeast worth trying in a wide range of beer styles.
