Default Is S-05 really WLP001?

I've been using it as such, but has this actually been confirmed? If so, why would anyone use the WLP at all?

It's reportedly the Chico strain. Which is actually WY1056 not WLP001

Yep, as far as I know, all three are the same strain.

Personally (and I have used all three), I just don't get the same results with dry yeast. It's probably something in my process, but it's there. I know lots and lots of people routinely use dry yeast with no problems whatsoever, but I always seem to get a "yeasty" flavor when I use dry yeast.

I've been washing yeast just about every time I brew a batch, so I always have 1056 available...so I just don't use dry yeast anymore, barring emergencies.

Never had a problem with dry yeast. I like the idea of more yeasties available without a starter .

If it resulted in the same taste as liquid with my brewing process, I wouldn't hesitate to use it. It's cheaper, after all.

Probably something I'm doing, like I said.

This is what I've been wondering. I think all of my beers w/ S-05 have been fantastic, but since I haven't tried out the other liquid strains I can't really comment. I've just always assumed they were the same based on what I've read in the forums and wanted to test that theory.

I'm in the same boat as Rick. I'm not knocking people who use dry yeast at all, so please don't take offense or start heating the thread up. But I gave US-05 a try very recently on two beers and it was very different from Wyeast 1056. I made 6 beers in a row from 1056, then 2 from US-05. The US-05 seems to be more temperature sensitive to me. I fermented at 65 with an IPA and a Barley Wine and got much more of an ester profile. Yeah, I know those are high gravity, but I've also made high gravity with 1056 many times and never had pronounced esters. To me, the US-05 just wasn't as clean.

The behavior wasn't the same as Wyeast 1056 and the flavor wasn't the same either.

Now, not saying you can't make a perfectly good beer with it. I'd need to make a few more beers using it and see what I have to adjust. But I've used Wyeast 1056 a lot in my life and US-05 just didn't seem the same to me at all. Maybe they both started off from the same point and then inhouse variations occurred at the yeast lab and they've now become two different strains. Or maybe it's just the difference between using dry and liquid. But whatever the case, to me, these two yeasts don't act or taste the same.

I believe WLP001 is same as US-05 or Wyeast 1056. There maybe differences in the pitching rates and so on, but essentially it's the same yeast.
I like to use US-05 a lot because I don't have to make a starter with it.

I agree when I use the dry it is a different beer. I prefer the liquid to the dry. I just think the profile is cleaner on the liquid and I can tell a difference in my beers.

I use 05 because of the price and ease of use. Its probably my favorite yeast. I ferment at 58-63. It is very clean.
