The Taste Test: Low-fat coffee
Wolfgang Puck Vanilla Fusion Iced Coffee
HK$19 for 251ml, City'super
Wolfgang Puck, the Austrian celebrity chef and restaurateur, says this organic coffee uses Tahitian vanilla - rather than Madagascan or Mexican - to give the drink a full flavour and sweet aroma. Each bottle contains 120 calories and 2.5 grams of fat.
Verdict: the sweetness and the vanilla overpower the espresso flavour. At 21 grams of sugar per bottle - more than five teaspoons - it's not really surprising.
Starbucks Coffee Frappuccino Light
HK$22 for 281ml, City'super
The artificial sweetener Splenda goes into this coffee, resulting in a drink that has 40 per cent fewer calories and 60 per cent less sugar than regular mocha. That comes up to 100 calories, three grams of fat and 11 grams of sugar per bottle.
Verdict: creamier than Puck's version but similarly too saccharine. Drink only occasionally, as excessive consumption of artificial sweeteners is linked with adverse health effects.
Tully's Coffee - Barista's Black
HK$17 for 285ml, City'super
The healthiest way to enjoy coffee is to have it black so it is calorie- and sugar-free. The only nutrient found in this drink is sodium - just a trace, at 26mg per 100ml.
Verdict: although I'm more used to having coffee with a splash of milk, this had a pleasant bitterness and a fabulous intense espresso flavour.
