My yeast is deceased

Yes - it's true. My Wyeast German Ale Yeast (ideal for Altbier) was dead on arrival at my house. It's not the fault of the extraordinary US beer yeast people at Wyeast Lab. Time of death for the little critters is unknown, but some time between the time over a year ago when they got sealed in their little plastic sachet (where they are only supposed to live for up to 6 months), and yesterday, when I burst the little container invisibly into the outer sterile culture medium. Sadly the supplier (who shall remain nameless) was to blame for loosing the pack in the back of the warehouse for quite a few to many months.... I did all I could to revive the patients with fresh food - but to no avail. RIP little chaps.
