Poor grape harvest to raise wine prices, Majestic fears In Britain, record rainfall left wineries with not enough grapes and led the country's biggest wine producer, Nyetimber, scrapped its entire harvest. Majestic sales Despite the washed our spring and early summer, Mr Lewis said Majestic had grown sales to commercial customers by 17pc over the past six months and there was "considerable potential for further growth" from selling to businesses. Majestic also saw a 14pc rise in online sales after the company reduced the minimum purchase to six bottles instead of 12. This has helped Majestic to attract thousands of new customers to its wines and sell more expensive bottles, as Britain's appetite for wine shows no sign of abating despite the economic uncertainty. "It would have been higher if not for a wash-out of a summer," Mr Lewis said.
