The seller says to store them in sugar.
I purchased my vanilla beans last September and I made two 1/2 gallon bottles of vanilla with about 1/4 of the beans. I have almost used up one bottle of the vanilla and when I break into the second bottle I will make a third bottle to let it sit and age. The vanilla by the way is out of this world!!!
We stored the vanilla in sugar as suggested and we are still using them. We use the vanilla sugar in our coffee every morning, adding more sugar as it gets used up. When we need a vanilla bean for some other application we just dig one out of the sugar and use it. They have been in the sugar for six months and they are still pliable fresh and fragrant.
