Three Choirs managing director Thomas Shaw said: "The purchase of Wickham Vineyard was partly driven by the very strong demand for English still wines, demand that far exceeds our current production levels.
"We are delighted to have purchased such a well-known vineyard and look forward to restoring it to its former glory as a producer of quality English wines."
The six-hectare vineyard, wine shop, restaurant, farmhouse and wine-making facilities had been on sale at a guide price of £1.6m.
Three Choirs has said it aims to reopen the premises in June, but expects to make the wine at its Gloucestershire plant.
Wickham Vineyard was forced to close at the begining of last year due to poor harvests over the previous two seasons.
