The infamous Wray and Nephew White Overproof rum has been available in the UK via Tesco for some years now. I imagine this is due to its huge popularity in Jamaica where it counts for 90% of all rum sales.
At 63% its not for the faint hearted, mind you neither is the packaging! It’s bold and slightly brassy. However the distinctive green and yellow bottle does stand out especially amongst the other white rums on the shelf. Rather than a metal screw cap it has a plastic screw cap and a diffuser in the neck of the bottle. This means the rum cannot be poured quite as quickly. At 63% ABV this is not necessarily a bad thing. A 70cl bottle costs around £25 in the UK. It is more expensive than other White Rums on the supermarket shelf but the extra ABV must be taken into account. You have in theory over a litre of a more standard 37.5-40% ABV white mixing rum in this bottle. View it as being concentrated.
