Picklewood siding is crafted from salvaged vat staves used to produce pickles, vinegar, and other foods in the 1800s; these redwood, cypress, and Douglas fir vats are being phased out in favor of fiberglass and stainless steel. The siding is available with the weathered exterior faces of the vats or processed to expose the clear material, the firm says. 877.375.2779. www.trestlewood.com.
