From Mark Gillespie's WhiskyCast website:
Kininvie was the “secret distillery” at the William Grant & Sons campus in Dufftown that is home to Glenfiddich and The Balvenie. It existed as a separate stillhouse near the Balvenie’s stillhouse, but shared mash tuns and washbacks with the Balvenie. The stills were also used to produce the Hazelwood-labeled single malts, most notably those honouring the late Janet Sheed Roberts, the last surviving granddaughter of William Grant.
The Kininvie stills ran only as needed to supply malt whisky for blending purposes, and there was officially never any intent to bottle Kininvie as a single malt — until now. In October, what is believed to be the first official bottling of Kininvie went on sale in Taiwan, with an estimated 7000 bottles.
