To be in accordance with the law, any drink with at least 15% alcohol by volume is considered a spirit. The information needs to be clear and concise on the bottle label itself and should include the name and address of the bottler, the country of origin, the net volume in litres, centilitres or millilitres, and the alcohol by volume as a percentage and any allergy declarations. It’s also important to state the use-by date, however, if the alcohol content is above 10%, this isn’t a requirement. You should also always state the implications of drinking when pregnant or when drinking and driving by adding a please drink responsibly reminder and should never downplay the strength of your product.
You should also include any types of spirits and flavours of your rum. For example, white rum, dark rum, spiced rum etc. You can also include information such as the rarity of the rum and where it is made so that you can persuade your customer to buy yours over your competitors.
