Where Glamis Castle sells
Auction-house breakdown for Glamis Castle — last 24 months. Pick the house with the most lots for the best chance of finding what you want; consider buyer's premium when comparing hammer prices.
Verify provenance. For bottles over £500, ask for receipts, original photos, and ideally a seller who is named on the auction house's verified accounts list.
Check fill level. Low shoulder fill on a 25+ year old bottle is normal; mid-shoulder isn't. Loss of liquid is permanent.
Inspect closures. Wax-dipped seals can hide damage. Loose corks risk evaporation. Reputable houses photograph closely — ask for higher-res images if not provided.
Compare hammer to wsky1 median. If a lot is >15% above our 12-month median, you're either bidding on something special (book, presentation case, signed) or overpaying.
Add buyer's premium + VAT. Your total is hammer × (1 + premium %) + any VAT. For a £1,000 hammer at Bonhams (27.5%) with UK VAT on the premium, your real cost is closer to £1,330.
Shipping & insurance. International shipping of spirits is restricted; many houses use specialist couriers. Get a quote before you bid, not after.
