JMK is a luscious fortified Shiraz, from fruit grown to select rows of the Kalleske vineyard, including the renowned Greenock block, vinified and vintaged on the family farm. JMK Port is dedicated to fifth generation grower, John Malcolm Kalleske, who has tended the Kalleske family vineyards for more than fifty years and continues to husband the very vines which are earmarked for JMK. A commemorative Vintage Port to honour the dedication showed by John and all those who came before him, toward their treasured old vines.

Shiraz is harvested in stages over the course of a fortnight, providing varying levels of sweetness and complexity for the finished wine. Grapes are vinified in open top fermenters and treated to a regimen of pumpovers twice daily. Several days after harvest, a portion of the free run juices are drained and fortified to arrest ferments and retain some natural sweetness. A combination of estate made brandy spirits, up to twenty years of age, are called upon to fortify the wine, achieving added complexity. Components are matured in well seasoned oak hogsheads for eighteen months, whereupon only the very best barrels are selected to be included in the final assemblage and bottling of this extra fine liqueur Shiraz.
