Storage times for liquid yeast for future brews

[PhillyBrewer]

I'm starting to create a brew schedule which will allow me to be drinking the beers I brew when I want to rather than continue the sporadic, disorganized brewing I've been doing. To that end, since I know what my next few brews will be, it only makes sense to order ingredients for multiple batches at once. If I order liquid yeast for a brew day that's 2-3 months away, will its viability be compromised too much? I plan on making a starter for these brews/yeasts and also plan on stepping them up (from a single vial) for a 10 gallon batch. Will the Mr. Malty pitch calculator answer all my questions?

Will the Mr. Malty pitch calculator answer all my questions?

Yes. There's a place in there where you can put the date on the package, and it will compute the viability for you and use this in its calculations.

[PhillyBrewer]

Yes. Using the calculator for a 1.055 OG, 5.25 gallon ale with stir plate, it appears that the number of liquid yeast vials needed changes from 1 to 2 at a production date 40 days in the past (2/20 for 4/3). So can I glean from this that 40 days is the limit?

I like to order yeast as close to brew day as possible. I'll order 3-6 months worth of bulk ingredients, but order just the yeast as needed.

I would think there would be a local home brew store where you could pick up your yeast in Philly without having to order?

[PhillyBrewer]

Indeed. I was just wondering how much time I had to brew if I did order yeast online.

I have brewed with White Labs yeast that was a month past the experation date, just did a good low gravity starter with Yeast nutrrient and O2 and the yeast came back super healthy made a 35 point beer with it.
