A Cornish vineyard owner has been giving evidence to a House of Lords committee on wine over-production.
Bob Lindo set up his business in 1989
Camel Valley Vineyard's Bob Lindo, chairman of the Vineyards Association, told the committee he was concerned about an EU ruling on vine planting.
When production in the UK rises above 2.5m litres then no more planting will be allowed in any of the 400 vineyards.
The move is to prevent overproduction which is regarded by many has more of a problem in southern Europe.
But Mr Lindo, whose still and sparkling wines have won many awards, says the ruling could create big problems.
The current EU planting ban comes up for review in 2010.
