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?
2026-09-17-replay/similarity-surprise/the-whistler-double-oaked-irish-whiskey-700ml-tamnavulin-dou-6897d7; window as-of 2026-09-17.Similarity surprise, light form. Two live tickets, each item's band-position label and own-history percentile, and the pair's CE rank. No CE 360° band numbers, no cross-read CEARP, no Welch t-test. Both bottles are on a My Dan Murphy's member offer this week; the band-position and own-history signals are read on the member price, so the basis is member-to-member and stated. The payload labels Tamnavulin Double Cask as 'Australia'; that is a catalogue error — it is a Speyside single malt — so the country/style surprise is described from the correct facts, not the payload's country field (see Notes).
