The server ranks companies on user-set weights across revenue growth, net margin, share price, wine share of revenue and distance from the 52-week high, and lists companies missing a weighted figure as unscored rather than scoring them zero. In its margin ranking, Laurent-Perrier leads at 16.3% while Treasury Wine Estates, owner of Penfolds, sits at −42.1%.", "body_md": "We put the VINCAP record of listed wine companies behind an MCP server, so you can ask Claude, ChatGPT or Cursor about wine stocks and get answers with the filing each number came from.
