Mind.  Blown. 

[neddles]

Interesting indeed.

maybe it's just the bo lager yeast is very forgiving?

[HVB]

Yes, that was a surprise to me.  I do not even start out that warm with ale yeast.

same here!

I just bought some 34/70.  This is of interest to me...

[positiveContact]

one thing to note is that he already did some similar experiments with other yeasts.  WL002, WL800 and  german ale/kolsch.

 

I mention this b/c I often skim over the start of these posts and head straight for the results.

[3rd party JKor]

I'm pretty sure I've already read through the previous experiments.

My only question would be his choice of yeast. My trusty Wyeast poster shows that 2124 is also known as 34/70 (I'm convinced that 2124 and 830 are not the same... their numbers do not line up) and my poster as well as other brewers state that 2124 or 34/70 have a sweet spot close to 70° where it will ferment cleanly at ale temps with lager-like characteristics. The exbeeriment is interesting, no doubt and I love Marshall's information. But I do wonder what would have happened with just about any other lager yeast that doesn't seem to have this sweet spot at a higher temp.

I had as well but I forgot until I saw the links on my second read through.

I was not aware that was the case.  It's good to know.

 

next time around he should try 2308.

2124 actually shows two "ideal temp ranges"... something like 48-54° and then 68-72° or something. Just thinking out loud.

but in between is no bueno?  strange!

He also ran one with WLP800 at 50F and 66F.  Same results.

I think it's time for this:

I don't think this is surprising considering I've done the quick lager method where you warm things up half way through and it works fine. I do think that it's likely to be strain dependent.

That's my primary method these days but I'm surprised to hear that fermenting a lager at 70F yields the same results as a lager fermented at 50F.

Very common yeast, likely used in a ton of different ways, I dunno. I'm just not surprised much anymore when it comes to beer.

I really shouldn't be.  nothing is sacred!

[SchwanzBrewer]

I also wouldn't be surprised if 4 more people ran this experiment and we got different results each time.

why would you expect that?

That's it. There's really nothing new there. That strain is well documented to work well up to 70F. The exberriment just kinda confirms what was already well known.
