"The yeast leaves a good body ... "
By: pdtnc
Date: March 4, 2010
Beers brewed: Bitter
Comments: I used this yeast for a Coniston Bluebird style of bitter, all Challenger hopped. The yeast leaves a good body with a subtle blending of the hops and malt but keep the hop flavour and aroma right where it should be. Quite possibly a yeast to keep as a house strain.

"I'm happy with the attenuation ... "
By: Joseph Reusch
Date: Oct 7, 2009
Beers brewed: Scotch Ale Wee Heavy
Comments: I brewed a big Wee Heavy with just Maris Otter and Roasted Barley using this yeast and it came out just delicious. OG at 1.90 and FG hit 1.018. I'm happy with the attenuation but even happier with the flavor of this yeast.

"This is a very versatile yeast"
By: d_h
Date: Sept. 30, 2009
Beers brewed: English Bitter, American Pale Ale
Comments: This is a very versatile yeast. Results are very balanced, enhancing both malt and hops. Responds very well to mash temperatures allowing creation of full bodied English ales as well as dry American beers.

"I will be making many more ... "

Beers brewed: Oatmeal Brown Ale
Comments: Quickly became one of my favorite yeast strands. I have brewed the same brown ale 4 times now, changing only the yeast and this is by far the best. Finishes clean leaving the malt and hops to speak for themselves. Leaves a slight pleasant fruitiness but nothing compared to SafAle04. Instead, it complements the malt and hides in the background. I highly recommend this yeast strain. I will be making my American Amber, American Pale, Irish Red, and many more with this yeast.

"My house strain ... "
By: Sam
Date: April 14, 2008
Beers brewed: Scotch Ale, Scottish 80-/, Irish Red, English "Stock Ale," many more.
Comments: My house strain and all-time favorite. Remarkable cleanliness in any malt-centric style. Finishes reliably and in moderate time, allowing far more malt aromatics than I've found with other strains. Versatile and neutral. Not recommended for any aggressively late hopped beers (American styles, IPAs), but balances bitterness in ESBs and barleywines well.

"WLP028 is now a 'default' strain for me"
By: Kris Olson
Date: October 23, 2007
Beers brewed: Wee Heavy, Pumpkin Ale
Comments: Used initially in my wee-heavy. Fermentation was vigorous and quick to complete without using a starter. Left a nice malty sweetness even when using British malts. Earthy and caramelly notes very prevalent, hardly any esters detectable. Enjoyed the sweet malt character this yeast preserved enough to use in on my pumpkin ale. Results were similar to the wee heavy - sweet maltiness preserved without outweighing the nutmeg, cinnamon, and allspice. WLP028 is now a "default" strain for me.

" ... strong attenuation and great malty flavor"
By: Ryan
Date: September 03, 2007
Beers brewed: Wee Heavy, Barley Wine
Comments: I've taken this yeast up to O.G.'s to the mid 1.090's. Fantastic for Scottish ales but I love this yeast for Barley Wine. This yeast has a strong attenuation and great malty flavor. Give it a try sometime.

"Notes of earthy stone-fruit  ... "
By: Anonymous
Date: March 21, 2007
Beers brewed: American Pale, Smoked Porter, Oatmeal Stout
Comments: Muted ester profile, with notes of earthy stone-fruit. Clean maltiness always comes through, but I've seen consistently lower attenuation than advertised (60 -65%), with a significant final drop in the secondary. Flocculates well. Starts well, if a little slow.

I have used White Labs yeast for years, and I recognized the benefit of liquid yeast from the first batch I made with it. I have used the "Edinburgh" yeast many times, and each time it has been great.
I just pitched a new batch this afternoon and I noticed something different about the yeast. It was darker in color than previous batches, and it did not have the very aromatic smell that I have enjoyed with previous batches.
Need I be concerned about anything?
 
The color can vary with our malt supply, but the there is no effect on the yeast. We usually try to keep it as light as possible for aesthetic reasons.
