Adding resin to wine is a process that dates back to antiquity when either pitch, pine resin or a combination of plaster and resin was used to make impermeable clay vases (amphorae) in which wine was transported. Ancient Greeks observed that pine resin not only helped seal the amphorae from moisture, but also helped to preserve the wine within. Pine resin may have also been used to squelch the scent of goatskin, in which wine was locally transported.
