"The future is bright for blueberry growers in the UK," he said. "Just two years ago UK production was 765 tonnes. This year it looks like we may achieve 1,200-1,500 tonnes."
Olins pointed out that this increase came as sales of all berries now represent 18 per cent of the total fruit category - expanding at four times the growth of total fruit.
"Berries are increasingly popular as people become aware of their health benefits. They're a snack and an ingredient so it's easy for people to include them in their diet."
Supermarket Sales - Berries top fruit chart
Berries have topped supermarket fruit sales for the first time, beating apples and bananas, according to Kantar data based on 52 weeks' trading.
Year-on-year sales have increased 13.3 per cent in the berry category. The total UK fruit market is worth £4.1bn.
British Summer Fruits estimated that UK-grown fruit accounts for at least 50 per cent of the total sales.
This year, summer sales have been helped by a warm and dry April that saw strawberries and raspberries on shelves a fortnight earlier than usual.
