The new gin liqueurs added to a standard G&T are a new craze sweeping the UK at the moment.
Gin Liqueurs are very versatile spirits that are generally served in one of 3 ways:
1. To complement a gin and tonic - e.g. 25ml Gin, 25ml Liqueur, 100ml Tonic, Ice and Garnish
2. Over ice - plenty of ice and 75ml liqueur
3 With prosecco - 175ml prosecco and 50ml liqueur
Either way these gin liqueurs really bring a drink to life. Gin Liqueurs are an alcoholic spirit with an ABV of 20%
