The short answer: what US shops are asking for that exact bottle, that exact vintage, today. The longer answer explains why two bottles from the same valley can be three times apart in price.
A bottle's value is not what you paid, and it is not the most expensive listing you can find online. It is the middle of what several retailers are asking for the same producer, the same wine and the same vintage. One listing on its own can be a six-pack, a large format, an auction lot or a typo.
When we priced every bottle in our users' cellars, those traps were common: a single "bottle" listed at $936 turned out to be a six-liter, and a four-dollar result turned out to be a gift shop item. Taking the middle of several real offers, for the exact vintage, is what keeps a cellar value honest.
People assume the region sets the price. Inside one region, the producer matters far more.
| Wine | Region | Retail today |
|---|---|---|
| Nalle Zinfandel | Dry Creek Valley | about $35 |
| Turley Old Vines Zinfandel | California | about $40 |
| Martinelli Giuseppe & Luisa Zinfandel | Russian River | $50 to $60 |
| A. Rafanelli Zinfandel | Dry Creek Valley | $68 to $85 |
Median of US retail listings, October 2026.
Rafanelli sells almost everything through its own mailing list and skips distribution, so any bottle you find in a shop is a resale. Scarcity, not the grapes, sets that price.
A typical Paso Robles Grenache sells for $25 to $35. Booker's "The Ripper" sells for $80 to $110, and its older vintages hold that price. A handful of cult Rhone-style estates in Paso price like Napa Cabernet, not like their neighbors.
Most bottles sit at $11 to $20. La Janasse asks $26 to $33 because it is a Chateauneuf-du-Pape estate making its Cotes du Rhone like a junior Chateauneuf. The producer's reputation travels down to its entry-level wine.
Brunello di Montalcino cannot be released until five years after harvest, two of them in oak. That cost of time puts a floor near $50 even for large houses; Ruffino's Greppone Mazzi sells at $60 to $86, and its Riserva, aged a year longer, at about $104.
Only wines with a track record of aging and steady demand gain value with time. A vintage Champagne from a grower can run three times the price of the same house's non-vintage bottling. An everyday red past its drinking window is usually worth less than it was on release, not more.
For older bottles, today's release price is a poor guide to what a 1993 is worth. If no shop lists that exact vintage, the honest answer is that it has no current retail price, not that it is worth the new release.
Caveau prices each bottle by its exact vintage from current US retail listings and shows the value per bottle, so six of one wine never outrank a single great bottle. It also tells you when to drink each one, and adding a bottle is a label scan.
