“24 hours from vine to brine” (pickling adage)

Cucumbers must be fresh—no more than a day from when cut from the vine—in order to make the best pickles. The old rule is, “24 hours from vine to brine.”
 
“Twenty-four hours from vine to brine is standard pickle practice” was cited in print in 1944.

Just a few “musts” must be considered to make a perfect pack. First is to use cucumbers soon after they have been snipped from the vine. Twenty-four hours from vine to brine is standard pickle practice.
