I built a sauna four years ago; it is lined with Eastern White Cedar. It
went in green and still has the wonderful cedar smell even when cold. I
keep two small windows open all the time. BUT, a wine rack made of EWS in
an open room would should have no detectable smell after a year of drying.
A wine cellar is usually a closed room; here EWS would not be such a good
idea.
