Convalmore 36 Year Old Prima & Ultima is a limited-edition Speyside single malt whisky produced at the Convalmore Distillery in Dufftown, Scotland. The now-demolished Victorian Convalmore Distillery was dedicated to producing its distinctively waxy make spirit for use in proprietary blends. This rare 36-year-old single malt was distilled in 1983, just a few months before the Speyside distillery closed its doors. It was bottled as part of Diageo`s Prima & Ultima series of rare malts in 2009.
