Further to a topic LE started earlier in the year on shelf life of liquid Yeast, I am doing a couple of "lazy" beers for comps using 05 and the new BRY 97 at the moment and as I hadn't used dried yeasts bar 05 for a couple of years had to re-educate myself on what needs rehydrating and what doesn't and optimum conditions for pitching.
An interesting fact I came across from research from Fermentis is that dried yeast at room temp loses between 30 and 40% of its effectiveness v's fridge stored which loses only 4% over 12 months, so get it out from the back of the cupboard and hide behind the eggs ;)
How long are they talking about for that amount of loss of viability?
I knew there was something I forgot :)
Wow only 4% in a year whodathunkit?
How do homebrew shops store them is important :o
Got BRY 97 going in 12 hours by rehydrating and oxygenating wort for 30 secs 1l/min.
I think that disposable O2 setup will be my next upgrade.

Your experience isn't typical (google)! Ali Kocho gave me the sachet and told me it lagged 2 days for him, and it did for me too. Maybe the O2 is the difference.
Ali Kocho Williams from UK ? :o :o :o
