1/The Glenfiddich Gran Reserva 21 is $331 on the shelf this week. Until last week a member could have it for $273; that offer has now ended, so for a member it costs more than it did.
2/The engine's second-closest match to it on flavour make-up is The Glen Grant 18, another Scottish single malt. That one keeps its price at $185. Same country, same style, one hundred and forty-six dollars apart.
3/The Glen Grant 18 is Speyside sherry-and-oak territory — an older single malt that has spent its whole life pointed at drinking rather than shelf appeal. Not the Gran Reserva's twenty-one years, but close company by profile.
4/Not the same whisky, and not a like-for-like pour. It's profile geometry: the model ranks the Glen Grant 18 second of the Gran Reserva's matches. $331 for the 21, or $185 for the 18? What's it going for near you?
2026-09-10-replay/value-pick/glenfiddich-gran-reserva-21-year-old-single-malt-scotch-whis-05e7f7, grounded on vintage 2026-09-10.r; harvest pair base 2026-09-03, latest 2026-09-10 (grounding.trigger.base_harvest / latest_harvest).None recorded.
Value pick, automated light form. The module payload carries two shelf tickets, the engine's ranks and scores, the saving and the week's event; it does NOT carry the reference's CE 360 jury, so there is no ten-seats read of the Gran Reserva here, and I open on the shelf ticket instead. The trigger is the reference getting dearer: a member offer on the Gran Reserva 21 ended ($273 for a member last week → $331 shelf this week) — disclosed as an offer ending, never as a repricing. Shelf basis this week. Candidate ranks in the reference's CE top-5 (CE rank 2, VSM rank 12).
