This is all pretty interesting in the theoretical/analytical sense, and knowledge is never a bad thing, but why do we care in the empirical/real world sense? Is this really telling us anything we didn’t already know from actually using these Yeasts?

For one thing, I think it highlights the need to rely on the empirical.  In choosing a yeast, knowing the source and lineage of a yeast bank's strain seems to tell you very little about how it will perform.  "Equivalents" are right out the window.

Right. That’s what I was driving at. Actual usage data and fermentation characteristics coupled with cell counting is the way to be.

It tells me that if I don't like US-05 or 1056, then I might still want to try WLP001 because that one is TOTALLY different.  Any similarities are like the difference between you and your 4th cousin twice-removed or something.

And this is only one scaffold of an enormous tree.

I definitely agree with you to a certain degree Dave, but difference between supposedly equivalent strains isn’t really new information. Certainly the additional depth shown here is new so I guess I am seeing it from the other side of the coin after all.

Okay, then... see HERE for MUCH more potentially bizarre relationships!:

Yeah, that's pretty much my thinking, too.

But Dave, that's already well known and documented.  Knowing the genetic history doesn't change anything.

BRY-97, WLP051, and 1272 aren't exactly the same, they should be really close.

Haven't tried BRY-97, but the genetics made sense to me from a sensory standpoint, because WLP051 is markedly different from 1272 (or BSI-72 or Imperial A15, which are all the same strain according to the Imperial guys).

So, where are we on whether 1056 is Sierra Nevada?  I have half a mind to try 1056 as a lager yeast, but the (dimmer?) half of my mind says to be sure, culture up from a bottle of SNPA.  But that of course introduces its own uncertainties.  (Addressing not the deep history of the strain back to Ballantine or wherever, but simply whether SN is really using a lager yeast.)

AFAIK, Wyeast cultured it from a bottle of SNPA.  But I don't think there's any reason to assume it's identical at this point.

So good reason to build up a starter from a bottle, then?

If that's what your curiosity drives you to do, sure.  I don't think I would.

If we keep agreeing on things Denny, we may cause a disturbance in the space-time continuum. 😂

Naw, I hope it hasn't come to the point where discussions are viewed as adversarial.
