" ...
flavor profile is excellent!"
By: jamie
Date: June 8, 2010
Beer Brewed: IPA, Pale, Porter,
honey-wheat
Comments: I've found that this yeast is not as others
have stated. Although I have been fermenting at the low end of the
recommended temp range (about 66F). I've been getting about 72%
attenuation. The flavor profile is excellent! The beers are very
clean. Some esters, but very subtle, probably due to the low
fermenting temp. I highly recommend this strain.

Comments: Amazing stuff! Was at full throtlle in less
than 18 hours and went from 1.094 to 1.024 in less than six days and
that was with 3 lbs of honey in the mix. Ends up dry but accentuates
the hops and malt character. Perfect!

Comments: From 1.073 to 1.017 in less than a day!!!
WOW! Poured the wort over the yeast cake from the previous brew.
Fermented at 19C. Excellent profile and balance.
Very dry unless lots of crystal or similar malt used.

Beer Brewed: Oatmeal Stout
Comments: Awesome English Yeast! My oatmeal stout had
an OG of 1.070 and it fermented out to 1.016 in 7 days at 68F. Too
dark to tell how well the yeast floccuated, but the beer does not
taste yeasty at all after sitting in a secondary for a week. The
thing that really makes this yeast stand out in dark beer styles, in
my opinion, is a very faint dark fruit/cherry flavor in the
background. Really compliments the roasted barley and carafa II that
I used. This just might be my "go-to" strain for future porters and
stouts.

Comments: From 1.060 to 1.014 in three days! Fermented
at 68F, it's fast and really brings out the hops. Fast, attenuates,
floccs. Why use anything else??

Beer Brewed: beer wine
Comments: I used an Amber kit, and added extra hops
and 5 pounds of dextrose. After 14 days in the fermenter, I bottled
it with just one small sugar-drop. I siphoned off a couple liters
(without bottling) for the weekend, and it tastes great right out of
the fermenter! Nice ETOH warmth going down, more like a strong wine
than a beer.
"To avoid
dangerous lag times ... "
By: Jim Givens

Beer Brewed: Chocolate Porter,
American IPA, English Extra Special, English Pale, Dry Stout
Comments: This rebel yeast lives fast and goes dormant
young – it’s in and out of solution long before the wort can
raise a wild posse. The beauty of this trait is that it’s easy to
get clear (and drier/clean tasting) beers out the door quickly. But
because of this trait it is also difficult to bring it back to
“life” to re-pitch it if it has been relatively still for only a
couple of days. To avoid dangerous lag times be prepared for some
yeast coddling if you use this re-pitching method, or use it
somewhat early, or double the amount of slurry pitched compared to
other yeast types to get the same degree of desired fast and furious
fermentation underway.
"This will

By: n35flyer
Date: Aug. 26, 2009
Beer Brewed: IPA
Comments: I switched over from California Ale, and
have been pleasantly surprised. Started at 1.074 and by the 6th day,
was down to 1.018! 80% attenuation is no problem. As advertised,
strain with terrific flocculent characteristics....this batch was as
clear in the primary after 6 days as others I have brewed that spent
a week in secondary. This will be my primary ale yeast from now on,
and I am anxious to see how re-pitching to a 2nd or 3rd batch turns
out.
"The
flocculation is also awesome ... "
By: Doug C
Date: April 9, 2009
Beer Brewed: IPA, Stout, Porter,
Pale Ale
Comments: I love this yeast. I moved from WLP002 to
WLP007 since it attenuates more. It seems to finish fermenting in
about 3 days on most of the beers that I have brewed. The
flocculation is also awesome - It ferments quickly then drops out,
leaving a very, very clear beer. The IPA that I brewed was with all
American citrus hops and there was no inharmonious flavor by
mingling the British yeast with the American hops. I have mainly
fermented in the mid 60s F so the esters are fairly neutral in my
opinion. I believe that raising the fermenting temps (to 70-72 F)
would provide esters that are more evident. This could have been
nice in the stouts since the roastiness could meld with some
fruitiness. This yeast will be the main
work horse in my stable of yeasts.
"I highly recommend it ... "
By: JJ Blanche
Date: April 5, 2009
Beer Brewed: English Barleywine;
American Strong Ale
Comments: This is now my go-to high gravity strain. I
highly recommend it for anything over 1.080, as it consistently
ferments down to the target FG without issue. Has more character
when compared to high-attenuating American strains, which I find
desirable. Has a fairly active fermentation, which requires a
blow-off unless you have the requisite head-space (carboys generally
don't, buckets and other vessels might). Can go right on up to the
stated 10% ABV and beyond, but starts to slow down when passing 11%.
Yeast nutrient helps, particularly when you want to push it up to
those levels. Minimizing blow-off by maximizing head-space is also a
good route to pursue if you want to draw as much out of it as
possible. I've used 007 with a 3 week primary, followed by a 3 week
secondary. Thereafter, let your high-grav brews sit for at least two
months after bottling. Give it time, in other words, and you'll be
rewarded.
"It is very

By: Steve Antoch
Date: Nov. 29, 2008
Beer Brewed: IPA, APA, ESB,
American Brown, Northern English Brown
Comments: This is my favorite "general purpose" ale
yeast. It is as attenuative as the 001 Cal Ale and yet provides a
nice malty emphasis. It is very clean and did a great job on my N.
Eng Brown down in the 62-64F range. I no longer use the Cal Ale in
my APAs and IPAs, because this yeast does the same job but leaves
the with a better malt backbone.
" ... can handle the higher

Beer Brewed: Barleywine
Comments: I used this yeast (propagated for the third
time) in an English barleywine that was 1.114 S.G. It was down to
1.032 within a week. Apparently it really can handle the higher
alcohol environment.
" ... started fermenting
extremely quick ... "
By: Mike
Date: Sept. 21, 2008
Beer Brewed: American Strong Ale
Comments: I was slipped this strain (accidentally)
instead of my old stand-by, the California ale. I didn't realize until
I was prepping a starter, but I had wanted to try this strain so I
went with it. This yeast started fermenting extremely quick and and
with in about 6 days had dropped the OG from 1.062 to 1.014. Lends
to a cleaner, less "Britishy" taste than the English and
British strains.
"This is one of my best beers

By: Taylor
Date: April 1, 2008
Beer Brewed: American Strong Ale
Comments: This yeast is very efficient, fast, and
clean. I brewed an American strong ale using only 2-row and some
120L Crystal and it was fantastic. The final ABV was around 7.5% and
masked very well. This is one of my best beers to date and can only
contribute it to the yeast. One note I will echo is that some
crystal malt should be used to prevent the beer from being too dry.

Beer Brewed: Russian imperial stout
Comments: I have been brewing 5 gallon batches of beer
for about 18 months and I don't typically use White Labs yeast. 007
was recommended for my imperial stout and I have to say that it is
pretty kick a-- ... with an o.g. in the mid 90's it dropped down to
high 20's in five days. I've pitched it since in a smaller beer with
good results so far, this stuff is super super fast ... thanks for
the yeast guys ...
"This is a great yeast strain"
By: Jim Snook
Date: August 14, 2007
Beer Brewed: APA, Old Ale, Strong
Ale
Comments: This is a great yeast strain. I use it now
for almost any kind of ale. Attenuation has been good, with no
off-flavors even fermenting up to high 70s Fahrenheit. It does
flocculate very well when done. Plenty of fruity aroma in the final
product. I always use some crystal/specialty malts in the grist with
this strain to keep the final product from being too dry.
"My house strain"
By: Mark Pannell
Date: June 26, 2007
Beer Brewed: APA, IPA, IIPA, ESB,
Irish Stout, RIS
Comments: I have made this my 'house strain' as I have
had such good results with it! It makes for a nicely balanced and
clean ale. It falls out of suspension almost completely, making for
a very clear ale. To my taste it makes for a more traditional
tasting Irish Stout. Perfect for any English-style ale.
"Lactose may have kept gravity
higher"
By: Ken Lee
Date: May 31, 2007
Beer Brewed: Russian Imperial Stout
Comments: After 10 days the gravity had dropped from
1.100 to 1.039. I was hoping for a faster drop in gravity, but due
to the addition of Lactose (6% of the grain bill) it may have kept
the gravity higher. It's got a month left to spend in secondary, so
hopefully it'll finish in the low 30's. Can't comment on
flocculation because it's opaque.
" ... behaved much as described."
By: Vertical
Date: Oct. 24, 2006
Comments: This strain behaved much as described. The high
flocculation allowed for great separation from the beer. I notice a
nice black cherry/fruity aroma. I am not sure of the attenuation
rate however. The wort started at 1.093 (a stout beer) and finished
at 1.030.
" ... I was quite
pleased"
By: Steve973
Date: November 20, 2006
Beer Brewed: ESB
Comments: This was my first time with using an English
ale yeast, and I was quite pleased. We first made a starter, and the
yeast took off quickly and the starter was at high krausen in less
than 2 days. The finished product resulted in an ale with a really
nice malt profile, so I'd recommend this yeast for brewers who are
making any kind of English beer, and especially for those making an
ESB.
FAQ for this yeast
Read other FAQs
I purchased a WLP007 for my Dry Stout recipe.
As I prepared to make a starter, I noticed
the yeast was considerably different than in the past. Instead of
being creamy and smooth after shaking, part of it was lumpy. The
question is, what’s going on here?
This is normal for this
strain as well as other very flocculent strains such as WLP002 and
WLP005. As we concentrate our yeast to a considerable degree, these
very flocculent strains will look rather lumpy.
