At the time of the grape harvest in Champagne, vineyards emphasize that a vineyard is more than just a property for sale. It represents an economic activity, a heritage, and sometimes a legacy spanning several generations. Philippe Petit, an oenologist by training and founder of VITACEAE Transactions, explains the complexities involved in these transactions and the key considerations before accepting a mandate. A real estate agent with a T card — a professional qualification — can legally present a vineyard property for sale like any other property. In practice, however, they face a unique reality: a vineyard sale is not simply a real estate transaction with vines. It is an operation at the intersection of land, rural law, and agricultural enterprise. The first step is to evaluate the vineyard as an asset of production, not just a property. The price of a vineyard depends on its appellation classification, its supply contracts, its stocks, and its mode of operation — such as direct value, lease, or sharecropping. A mandate that sets a price "on the market" without thoroughly examining these factors risks undervaluing the vineyard or creating a file that will never lead to a sale. A vineyard sale also involves navigating a dense legal environment. This includes understanding the status of lease and rural lease, notice and right of reclamation, preemption by SAFER (a public organization that protects agricultural land), control of structures and authorization to operate, and since July 1, 2022, the control of takeovers of companies under the Sempastous law (rural code, articles L. 333-1 and following). Each of these legal aspects can cause a transaction to fail if not properly addressed. The intermediary, such as a real estate agent, does not provide legal advice — that is the role of the notary and the lawyer — but must know how to identify the key points of attention and coordinate the right contacts at the right time. Vineyard sales also typically occur off-market. The best vineyards are not listed on real estate portals; they are sold in confidence to a restricted circle of qualified buyers. The expertise lies not in publishing an ad, but in knowing, by name, who the buyers are, and in preserving the seller’s discretion — a condition often set by the seller. This requires speaking the language of the winemaker. Over the past 25 years, it has been observed that a seller entrusts their vineyard to someone who understands what they are transmitting — a heritage, a skill, sometimes spanning ten generations — and not just a surface to commercialize. Selling a vineyard involves balancing agricultural value, business value, and heritage value within a fluid regulatory framework and an opaque market.

An oenologist by training, former licensed wine broker, and holder of an MBA, Petit is from the tenth generation of a family of Champagne winemakers. He operates on the sale and purchase of vineyards and houses under off-market mandates. He is also an honorary judge of the commercial court.
