The fluffy one is right. Please permit me to add my $.02 worth.

You didn't say the species of your wood which makes a huge difference. 
But the observation that I'd like to throw in is if you're scion wood 
calloused you may be storing it too warm. Also forming callus takes 
energy out of the scion wood and in all likelihood will reduce the 
amount of successes you will have grafting it. Store your scion wood as 
close to 32 as you can get your storage unit, I suspect your 
refrigerator is set at about 45°, which is too warm. Just checked the 
temperature gauge in my refrigerator a few days back and it said 28° . 
The water jugs I keep in there to reduce the cycle times was not frozen, 
however frost does often form in my bags of scion wood and I've not seen 
any indication that it hurts the scions.
