New Zealand wine is the drink of choice for many Americans who would rather pay more for a bottle than get it from Australia.
Bloomberg reported the value of Kiwi wine shipped to the US jumped 11 per cent to $400 million last year - the biggest gain among its top eight importers.
The gain exceeded Australia's earnings there for the first time, according to Bloomberg and figures obtained from Gomberg, Fredrikson & Associates.
Aussie shipments reportedly dropped 8 per cent, and Argentina's fell 4 per cent.
Melbourne-based analyst Marc Soccio from Rabobank told Bloomberg the increase in exports was due to US drinkers becoming more discerning.
