North American Black Cherry – Kiln dried OK to store in cold?
I have to store a lot of Cherry for 18 months. Material is kiln dried to 6%. I’ve been told this will keep it stable. The mill insists that as long as it’s kept under roof and dry, that it can be stored without the need for temperature or humidity control.
Obviously before using the material it would be aclimated for a few weeks.
OK to store this way?
Thanks for any opinions.

I would think it's OK - it's difficult to control temperature and impossible to control humidity - you can test it again 2 months before you finally use it to see where you are but I think the mill is advising you correctly.

SA, thank you very much for your input. My understanding is that if you dry to 6% the wood cannot re-hydrate unless submerged in water. Also 6% leaves insufficient water to expand when frozen and crack the wood. Lastly, the NA Cherry is supposed to be particularly stable in this regard. Softer than many hardwoods but very stable. So I'm hoping it deals with the heat and cold of the seasons OK.
Thanks again.
Wood is a hygroscopic material. It absorbs and desorbs moisture in relation with relative humidity. Kiln drying does not alter this process. Kiln drying speeds up the drying process and allows the kiln operator to control the process. If done properly the wood has less defects than if it were only air dried. The cherry in question shiuld be moisture tested when you are ready to use it. If it is more than a couple % higher than what it will become in your house than bring it inside to acclimate to that enviroment.
