In order to produce a full flavored marmalade the Whisky is added after

On the far edge of the Scotch whisky map, it's supposed that the art of
distillation was first brought to Islay by Irish monks. Being remote
it's an art that flourished in the hands of the islanders, whose illegal
operations tested the resolve and means of the tax man. Eventually, the
law relaxed, various whisky makers set up legitimate distilleries,
among them a pair of farmers, Donald and Alexander Johnston, who in 1815
founded their distillery on the island's south coast. Laphroaig so
called after its location, 'broad hollow by the bay.' It would remain in
family hands for the next 139 years.
