Practical Brewing Notes
W-34/70 is a good choice when you want a lager strain with a long track record and a wide comfort zone. It gives brewers a realistic path to clean lager beer without relying on liquid yeast scheduling, and it remains one of the safest dry options for keeping a lager batch on track.
Because this is dry yeast, it is generally less risky to ship than liquid yeast. That said, avoiding unnecessary heat and long transit exposure is still the smart move whenever possible.
