1/Here's a pairing you'd never shelve together: The Whistler Double Oaked, an Irish blended whiskey, and Tamnavulin Double Cask, a Speyside single malt. Different countries, different styles. The engine ranks them second-closest of anything on the shelf.

2/Worth being clear what that means: it's profile geometry, how the two sit against each other on the model's flavour axes, not two glasses poured side by side. Both lean sweet and easy, gentle sherry-and-orchard territory rather than smoke.

3/The timing bit: both are cheap right now. Each is under its own cohort's floor and at the bottom of its own recent price range this week. That's on a My Dan Murphy's member price — $62 for the Whistler (list $69), $66 for the Tamnavulin (list $79).

4/Two independent measures agreeing on both bottles at once is rarer than one doing it alone. Which would you reach for — the Irish blend, or the Speyside malt?
