SafLager W 34/70
Great yeast, very clean fermentation, and high attenuation. I have used it when fermenting under pressure, up to 15 psi with great results.

Never thought a dry yeast would outperform a liquid yeast ! (Vienna Lager)
I have been brewing since 1994, and exclusivly used liquid yeast that became easy to find since then.
I only used 2- 11.5 gram packs in a 11 gallon conical fermenter. Pitched in at 49F. then slowly ramped up to 64 over 10 days, held there 2 days, then slow cool 2-3 degress/day down to near freezing to Lager 2-3 weeks.
The results were spectacular! Very clean, maltiness from the Vienna malt and Pilsner malt shined through. Hops were snappy enough to balance the Malt, as the yeast played out so clean.

I love this yeast!

Really enjoy using this yeast
Been using this yeast a few times recently after I started pressure fermentation in a korny keg. Beer turns out great and I can get it done in about a week and the beer has been clean and crisp. Used it in a German Pilsner and the Morebeer Cerveza kit. The Cerveza needed some time to clear up but tasted great. Will use again.

Probably the best yeast on the planet...
Torture it at 48F for weeks. Or spund it at 68F and 15PSI for a few days. You'll get clean, crisp beer that does a great job highlighting hops.

I don't even bother having US-05 or Nottingham in my yeast library anymore. If I want a clean ale, I use this lager lol. If I want a real ale, I use boddington's or fullers.

Amazing stuff!!
I Lagered my first ever homebrew because it was the middle of winter. I heard that lagers can be tricky but this stuff turned out beautifully!

3 weeks in the fermenter at 63 deg. 3 weeks bottled at 68 deg and this is BY FAR the best beer I have ever tasted - ever! The heavy sedimentation really left a clean final product with no filtering. I used US-05 on the next batch and did not end up with as clean a beer. I can’t wait till next winter to brew with this again!
