1. 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.
2. Check fill level. Low shoulder fill on a 25+ year old bottle is normal; mid-shoulder isn't. Loss of liquid is permanent.
3. Inspect closures. Wax-dipped seals can hide damage. Loose corks risk evaporation. Reputable houses photograph closely — ask for higher-res images if not provided.
4. 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.
5. 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.
6. Shipping & insurance. International shipping of spirits is restricted; many houses use specialist couriers. Get a quote before you bid, not after.
