Wine is an extensively traded product that is a common target for retaliation in trade disputes. We analyze the impact of tariffs and tariff retaliation by estimating a structural gravity model of global wine trade. We then simulate the effects of tariffs and tariff retaliation, as well as the effects of trade liberalization, on trade and welfare in the international market for wine. We show that recent trade disputes threaten to reduce wine trade by nearly $340 million annually and significantly reduce consumer welfare, while complete trade liberalization would expand trade by roughly $76 million.
