Check out the 10 risers and fallers on BordeauXchange. The % increase/decrease displayed is based on each wines market price movement over a 1 month period.
The price movement must be supported by either a similarly priced bid to buy/offer to sell, or a recent trade. This ensures that the price change is genuine and backed by real transactional prices, rather than advertised prices which can often provide inaccurate valuations.
The list is updated on the first week of every month and can be viewed on the BordeauXchange Trading Desk.
