Dry yeast for German pilsner?

[Steveruch]

It is indeed W-34/70

My bad; not sure where I picked up the S.

Because they use 'S-' with their other lager strains, S-23 and S-189.

I'm glad someone does.

It's my current favorite dry lager strain! It ferments fast and clean, and drops clear super quick. I've done two rauchbiers, a Vienna, a doppelbock, and a schwarzbier with it. I've read that it's tolerant of higher temps like 34/70, but I haven't tried that yet. Overall I'm really impressed with Diamond Lager and recommend it highly!

What temp(s) do you use Diamond at?

And do you dry pitch or use starter?

Another option is rehydrating, but I get good results with dry pitching.

I usually shoot for around 52-54 F for 7-10 days, then boost it 5 degrees a day up to 65 for a few days, then crash and keg.

And do you dry pitch or use starter?

I rehydrate.

I've tried 1 pack of w34/70 around 60F (per the warm ferment threads) and got esters. Tried 2 packs at 54F and still wasn't impressed (esters). So I spoke with a head brewer that was well versed with this yeast (aka their old brewery used this strain a TON). They recommended a VERY heavy handed pitch around 49F to 51F. I got a pack of w34/70 and built it up over time on the stir plate to an estimated 800-900 billion cell count. I used this method because the homebrew shop charges almost $8 a pack for w34/70. Pitched that at 49F and I'll be damned...It was actually clean! Seems like this yeast is finnicky so if you were going to ferment at 54F I'd recommend 4 packs at the very least. 49F would need 8 packs.

Thank you for the 34/70 comment on flavor and temperature quirks.
I thought I'd gotten a foul packet or an infection when first using that dry strain near 60F. My first and only 34/70 beer turned out with a moderately acidic tang I didn't like and out the door it went.

 

[Dland]

I've had made some pretty good lagers fermenting 34/70 in 54F range, I wonder if there might be other process variables?

Acid tang has not been a problem in over 30 brews with it, sounds like partial "infection".

I do agree that fermentation on the cooler side makes better tasting beer, but that is true of all lager yeasts.

I also tend to pitch on the light side compared to others, but do usually oxygenate well.

Same here. I have no complaints with it.

 

[Mer-man]

Makes you wonder about the palettes of those whose p-value show no difference, huh?

 

[passedpawn]

I stopped using w34/70 after some odd estery results with pilsners. I'm 100% using S-189 now. In fact, brewing with it this wkend

Time to find a new homebrew shop?

 

[Comfort_Zone]

W34/70 is a perfect yeast for a German pils.

Labelpeelers has very good pricing on their dry yeasts, $5.65 for W34/70 with free shipping. S-05 is $3.05 and that is shipped.

Ritebrew is good as well. I just bought 10 packs if 34/70 for about 4 ea

 

[smata67]

Ritebrew would be $6.69 shipped for this yeast. Not bad. But LP price is kind of extra-ordinary for a single pack, I don't see how they are making any money on them. I ordered this morning and already have a tracking number, should get in 2-3 days with First Class shipping. I have to believe LHBS are doomed, deals everywhere.

I have to believe LHBS are doomed, deals everywhere.

That’s why it’s up to us to support our LHBSs! If you live in a city with a LHBS, please support them - even if their yeast costs a dollar more! Helping sustain a local economy is worth the dollar! (Obviously if your LHBS doesn’t have something you need - to the internet!)

So, can a single pack of w34/70 be pitched into 5 gallons of 1.051 pils for fermentation at 55F? I am aware the calculators dish out very large cell counts for lagers, but in actual practice, should I be okay with this? I would also be pitching nottingham into similar conditions (altbier) and kept in the same fermentation chamber, so the 55F is an attempt to keep both happy. I would have the option of reducing the volume if necessary.

Yes, not problem at all. Have even pitched a single pack into 10 gallons and it came out great. I generally run it at 54-55F also, with a D rest in when it begins to slow down or about 1.020-18, good time to spund it too.

 

[Home_alone1]

I pitch 2 packs of 34/70 into 5 gallons at 50 degrees and then let it come up to 55 degrees for fermentation. As soon as the krausen starts to fall I let the temp rise for my d rest . I’ve been making pretty good lagers the last 6 months or so, before that I had some issues but I’m still learning, brewing and learning !

I use 34/70 because I can get it cheap at my lhbs vs other yeasts . I’ve stopped doing anything but lagers because of that.

I've made a few alts at about 60F with good results, and have used w34/70 at the same temp, with good results as well. Many people have reported success with w34/70 in the mid-60s.

FWIW, I recently did a split alt batch with Nottingham, S-04 and K-97, followed by a blind taste test. I preferred the K-97, with S-04 a close second. The Notty ended up a little boring. For what it's worth.
