Storing Dry Yeast
« on: October 22, 2015, 11:52:30 PM »
I typically (my handful of Belgian brews) use liquid yeast but am planning on using dry yeast for some upcoming beers.

Any special considerations for handling, storing or using dry yeast?

Keep in the fridge. Hydrate or rehydrate, I don't care. ;)

I keep it in the butter tray of my keg fridge.

Proper rehydration before use is a good idea. I pour the dry yeast over 4 oz luke warm water. Leave that 30 min. Stir. Add 3-4 oz wort from the batch. Leave that 30 min. Then pitch.

I have never perceived a benefit with rehydrating dry yeast compared to just sprinking it dry onto your wort. Since it's easier to sprinkle, I just go that route. You can certainly rehydrate if you like, but I don't feel that the extra step is necessary.

As far as storage goes, just keep the packets in the fridge. I always keep a couple of packets of US-05, 34/70 and 71B (for meads and ciders) in the fridge at all times for impromptu brewdays.

Dry yeast can even be kept in a freezer because there is no water to rupture the cells.

Do the basic calculations for liquid yeast viability apply to dry yeast?

No. Mr Malty has a dry yeast viability calculator. It is a much slower rate of loss of viability.

All of my dry yeast is in the freezer.

I keep my dry yeast in my crotch...the local colony can be reused just by simple methods of building the local colony to a pitchable number

Though now that I think about it these yeast are in a somewhat humid and worm environment
