Currently the import of European wine (and the vast majority of investable wine is European) is simple and easy. Trade rules after Brexit would have to be negotiated, for if importing becomes costlier then, we can expect the value of wines already in the UK to increase.
There will be negative effects for the English wine industry, however. The removal of free trade with the rest of the EU would most likely have a negative impact on exports to these markets. The restriction in low-skilled, migrant labour after a Brexit vote is likely to increase labour costs in the UK. This would undoubtedly have a negative impact on the cost base for wine producers. With the introduction of trade tariffs and the weakening of the pound, wines from the EU will be more expensive for UK wine buyers. With the exception of Chile (whose wines currently have tariff-free access to the EU thanks to a free-trade deal), and to a certain extent South Africa (which has a quota agreement where around a third of its exports to the EU enter duty-free), New World wines would feel relatively cheaper should we leave the EU without negotiating a deal.
Does this mean we would have to venture to the New World for more affordable wines? And will we lose the charm of the Old-world wines?
All the countries of North America (Canada, United States), South America (Chile, Argentina, Uruguay), Oceania (Australia, New Zealand), as well as South Africa now provide us with an infinity of choice. And the vineyard, as a rule, was brought there in the past 400 years by inhabitants ... of the Old World! During the voyages of the great explorers, the French, Dutch, Italians, Spanish and Portuguese took with them their love of vine and wine, and propagated this culture.
But more than two distinct sets of countries, the terms Old World and New World also refer to a style. The wines of old Europe are generally considered to be more delicate, complex, elegant, contained, with more acidity and more ageing. The stereotype of New World wines perceives them as being less complex than old world wines, have too much alcohol, being mass produced, and it is thought that one has to spend more on a new world wine to get the same quality of the old-world wine. But this is certainly not the case! The wines of the New World are shown as being more jammy, greedy, and woody, less austere and acidic, remarkably fruit driven, and incredibly complex.
The old world has developed a culture and know-how that have crossed the ages. The practices of the new world are increasingly focused on quality, with ever more modern techniques and innovations.
The passion of the vine and wine, already present in several countries, now spreads contagiously throughout the world.
