Berry Bros. & Rudd Realizes £614,370 in Ian Mill KC Cellar Auction

Market Pulse

The Berry Bros. & Rudd auction of the cellar of Ian Mill KC concluded on November 6, 2024, achieving a total realization of £614,370. The event saw a perfect 100% sell-through rate across 575 lots, indicating a highly engaged audience for this single-owner collection. The average bottle price for the sale stood at £712.25. Competitive bidding was a hallmark of the session, with 21.1% of lots exceeding their high estimates, while only 1.9% finished below the low estimate. This performance suggests strong confidence in the provenance of the collection.

Record and Breakout Lots

California’s Ridge Vineyards Monte Bello emerged as a primary driver of record-breaking activity. Multiple vintages reached new price ceilings, significantly deviating from their historical medians. For instance, the 1990 Ridge Vineyards Monte Bello reached £660, representing a 197.4% deviation from its median of £221.88 over the last five transactions. Similarly, the 1977 and 1988 vintages both achieved records at £660 and £510 respectively. Beyond California, the 1964 Château Cheval Blanc reached £1,440, nearly triple its recent median price of £492.22. These results reflect a premium often associated with well-documented single-owner provenance in the current market.

Soft Spots and Bargains

While the vast majority of the sale performed within or above expectations, eleven lots failed to reach their low estimates. Notably, the 1990 Riesling, Clos Ste Hune from Trimbach sold for £510 despite a low estimate of £800. Similarly, the 2002 Mazy-Chambertin from Domaine Armand Rousseau realized £840 against a low estimate of £1,000. These instances highlight that even within a high-demand auction, certain blue-chip labels can occasionally underperform their expected valuation ranges when compared to broader market benchmarks.

Spotlight: Mature Bordeaux and California

1964 Château Cheval Blanc, St Emilion The sale of this mature Bordeaux for £1,440 marked a significant departure from its recent history. Based on a series of equivalent bottle prices from trusted auction houses over the last 365 days, prices had fluctuated between £314 and £1,147. The previous high in this period was recorded in September 2024 at £793. The current result represents a substantial increase over the recent max observed in the preceding year.

1988 Ridge Vineyards, Monte Bello This lot realized £510, a price well above the historical range of £124 to £240 seen in the last 12 months. Recent transactions at Zachys and Acker Merrall & Condit in late 2024 showed prices closer to the £164-£191 range. The jump to £510 at this auction is a notable outlier compared to equivalent bottle prices recorded within the last year.

2020 Latricières-Chambertin, Grand Cru, Domaine Launay-Horiot This young Burgundy realized £276, surpassing its recent peak of £179.68 recorded at Zachys in June 2024. Over the last year, prices for this wine at Hart Davis Hart and other major houses stayed largely between £104 and £150. The current realization represents a 141% deviation from the recent median of £114.52.

1985 Château Haut-Brion, Pessac-Léognan The 1985 Haut-Brion realized £900, which is more than double its recent median price of £429.90. This bottle has a dense history of transactions over the last 365 days, with 16 equivalent bottle results ranging from £215 to £688. The result at this auction sits significantly above the previous high of £688 recorded in December 2023.

Outlook

The 100% sell-through rate and the high count of 128 records suggest that collectors are currently willing to pay a premium for single-owner collections with clear storage history. The dominance of Ridge Vineyards among the top overperformers indicates a potential focus on mature California Cabernet. However, the underperformance of select white Burgundy and Alsace lots relative to their estimates serves as a reminder of the price sensitivity that remains for specific categories outside the primary spotlight of the sale.
