This listing's current published materials advertise Wagyu, but the offering does not meet our full verification standard for provenance. It carries no authenticity badge; undisclosed details remain explicitly unverified.
Why it's listed
Lone Mountain Ranch is a historic 148-acre guest ranch and resort in Big Sky, Montana, dining at two rooms above one kitchen. Horn & Cantle is the public farm-to-table restaurant (breakfast through dinner, Resy reservations), whose current dinner menu is Montana-sourced beef, bison and trout with no Wagyu listed. The intimate Auric Room 1915, open to members and on-ranch guests, runs a nightly-changing menu that features Japanese A5 Wagyu, an A5 Ribeye, an A5 Sando and an A5 beef tartare among them. The ranch is marketed as the first certified Kobe beef purveyor in Montana, though Kobe is not a fixed item on the published menu.
Authenticity flags
- The ranch's Auric Room 1915, an intimate supper club open to members and on-ranch guests, is marketed as Montana's first certified Kobe beef purveyor, but its published menu changes nightly and does not list Kobe as a fixed dish; the beef it does name is A5 Wagyu without a stated Japanese region. If eating certified Kobe is the point of your visit, ask whether it is being served the night you are booked.

Common questions
- Does Lone Mountain Ranch serve real Wagyu?
- Its own current menu advertises Wagyu, and that claim was read directly on July 22, 2026. What the menu does not do is say which Wagyu: no prefecture, grade, breed status or producer is published, so the sourcing cannot be checked from outside. That is a gap in what is written down rather than a suggestion that anything is wrong with the beef, and plenty of kitchens buy carefully without printing the details.
- What kind of Wagyu does Lone Mountain Ranch serve?
- Its menu discloses A5 Japanese. Each of those is taken from the venue's own current materials rather than from a review or a listing site, and the evidence behind it is quoted further down this page.
- Is the Wagyu at Lone Mountain Ranch Kobe beef?
- It is licensed to serve Kobe and was not listing it when we last looked, on July 22, 2026. This venue does appear on the official Kobe registry, but Kobe was not on the menu at that check, so no Kobe badge is shown. Licensed rooms drop it between allocations and bring it back, so this can change without notice and is worth asking about directly.
- Why is Lone Mountain Ranch listed without a Wagyu badge?
- Because a badge here means the sourcing was checked, not that the food is good. This listing is published because the venue genuinely advertises Wagyu on its own current material, and it carries no badge because that material does not say which Wagyu. If the venue publishes the prefecture, grade, breed status or producer, the listing can move.
