In the nose, there are differences in the area of fruit flavors. Spock is a bit spicier on the tongue, but Kirk is a bit fuller in character. The differences, however, are not as significant as to make one of them more unbroken than the other. A draw.
Comparison with Cragganmore 2005 ( https://www.whiskybase.com/whiskies/whisky/101191/cragganmore-2005 )
Spock = Cragganmore 1990
Kirk = Cragganmore 2005
Spock: orange zest, almond oil, hazelnut, a lot of malt & cereals. A little waxy, but altogether rather airy and fruity.
Kirk: More pronounced in the orange note than Spock. Less nutty, less almond, malt and cereal flavor in something the same. In addition to the fruit also floral with a slight scent of tulips.
Spock: Mild approach to the aromas of the nose: nut, almonds, oranges, toffee, cocoa, milk chocolate. Later, wood pulls through and a slight pepper sharpness makes itself felt.
Kirk: Creamy and slightly fuller (voluminous would be too much) on the tongue than S. Also here are toffee sweets, cocoa, milk chocolate with nut, latte. Less peppery than Spock, as well as less wood content.
Spock a bit spicier, Kirk a bit finer.
