Mauritius produces a wide range of cane rum. It is very cheap and is a nice drink when mixed with cola and ice. Don't forget the coconut water with a dash of lime and a splash of local rum over ice. The serious amateur will try to find a bottle of five years old or older rum. Worth the price difference!
If you are staying in a hotel where the drinks are wildly expensive consider collecting your tipples while you are out and about from the local village shops or supermarkets where the prices are much cheaper.
The local beer Phoenix costs around 30 rupees less than one pound sterling for a pint. Usually served very cold.
The local Black Eagle beer, brewed in Nouvelle France is one to watch out for as well. Definite refreshment to match the sweltering summer heat.
Try visiting the Medine Estate Refinery shop at Bambous 4 km from Flic en Flac, on the west of the Island, for a wide variety of locally produced rums and liquors.
