Larger starters for lager

[EalingDrop]

Cheers for the info lads, I have blind faith in the 1.5L starter I have, as it smells & tastes fine, I'll step it up to a 15L kit brew, then run with that.

How did it turn out? I've got the White labs German Lager yeast (WLP830) stored for 8 months old. Made the starter last night and I have 36 hours before brew day.
Can viability be judged by sight/taste/smell?
