Yet another 34/70 thread

34/70 is said to be equivalent to WLP-830, Wyeast-2124, and Imperial Global according to several internet sources, althrough MrMalty.com says WLP820 is the equivalent to WY2124 and Wiehenstephen 34/70. MrMalty says WLP830 is the same as WY2206. The genetic analyses here seems to tell a slightly different story: http://beer.suregork.com/wp-content/uploads/2019/10/Brewing_yeast_tree_Oct_2019.pdf. (lower left). 2124-B is very close to 2206 and more distant from 830.

Seems to me there is no substitute for experimenting and deciding for yourself which gives you the best results. I wouldn't hesitate to use any of them.

 

To re-enforce what @pweis909 posted above, recent genetic testing indicates that W-34/70 is genetically different from WY2124 and WLP830. Having stated that all of these yeast strains will produce a fine Helles beer. Choose which brand/format best suits you.

Cheers!

 

If you’re looking for a clean lager yeast, 34/70 is about the cleanest out there. Basically neutral flavor profile. I think it’s almost too clean, but that’s just my opinion.

 

Lallamond Diamond could be added to the dry equivalents. Im using it as it has a simular flavor, clears faster, and is a buck a sachet less.

 

Jeff, how many sachets do you use for a moderate gravity (e.g., 1.050) lager? Do you direct pitch?

Any idea what is the source for this yeast strain?

Cheers!

 

I'll add Mangrove Jack's M76 Bavarian Lager to the dry yeast options. It makes excellent German-style lagers, clean, malty, and it clears well too.

 

1g/liter works just fine.

I first pitch.
Some say it is a Weihenstephaner 34/70 isolate. Who knows what it really is until the genome is mapped and compared.
