Amrut Portonova is an un-peated single malt whisky matured initially in a combination of new American oak and ex-bourbon barrels, which is then transferred to once-used port pipes imported from Portugal and then finally back to ex-bourbon casks again. It is aptly named Portonova as there is a town called "Portonovo" on the east coast of India, that was under Portuguese control from the 16th to the 18th century.
