Yes, visitors to Grand Cayman aged 18 or older are legally allowed to bring a limited amount of alcohol into the country duty-free. As of 2026, the allowance is typically one liter of spirits (liquor) OR four liters of wine OR one case of beer (not exceeding 8 liters). You must declare these items to customs upon arrival. If you exceed these limits, you will be required to pay a customs duty and environmental tax on the excess amount. While many travelers bring their own specialty brands, Grand Cayman has a wide variety of local liquor stores, such as Jacques Scott, which offer a broad selection of international and local spirits. It is worth noting that while the legal drinking age in the Cayman Islands is 18, public intoxication and drinking in non-designated public areas are strictly prohibited and can result in significant fines or legal issues.
