## Question
I've searched everywhere.
No Wikipedia page.
No information on NCBI.
I searched all occurrences of 34/70 in some primary research articles!
The best I've found is this brewery forum where someone asked the same question.
And the user rockfish42 answered:
No idea why they use that number, but it's the catalog number at
Weihenstephan's hefebank.

I went to the Yeastbank website at Weihenstephan for some info. The keyword here is "Stamm," which is German for stem, clade, clan, or strain. So, I would take this to mean that the 34/70 is an isolate (#70) of strain 34. Two of 34/70's strengths, according to the link above are it makes clean beer and gives a pleasant taste profile due to its low yeast-like aroma in the finished beer. I can attest to that firsthand, having had on numerous occasions the pleasure of partaking of Weihenstephaner beer
