Beverage companies producing soft drinks containing more than five grams of sugar per 100ml will pay a levy of US$ 25 cents to the UK's Treasury. If more than eight grams of sugar is served in a 100ml drink, the sugar tax increases to US$ 34 cents.
Old favourites including Original Pepsi and Coca-Cola Classic, which has around seven teaspoons of sugar in it — won't change their recipes — but they will attract the levy — so a can of Coke will increase by US$ 11 cents.

The British government had hopes the sugar tax would raise US$731 million (£520m) over the next year and cut the nation's obesity rate, however 50 percent of drinks manufacturers have changed their sugar formula, which isn't to all of their customers taste.
The Office for Budget Responsibility estimates the sugar levy will raise US$337 million (£240m) after four of Britain's major supermarkets reformulated their own label drinks to avoid the sugar tax, Tesco estimates 85 percent of its drinks will be exempt from the levy.
A Co-op spokeswoman said in a statement: "The levy is designed to be passed onto customers and drive a change in consumer behavior so, for branded soft drinks that do qualify, we will pass on the cost of the levy and the VAT."

Meanwhile Christopher Snowdon of the Institute of Economic Affairs, a registered charity, says the sugar levy "is a cynical revenue raising device", and won't help cut the rate of obesity in Britain.
"The sugar levy is a cynical revenue raising device that will clobber people on low incomes," Snowdon says in a statement.
"The British public are being treated like children. Thanks to the sugar levy, several iconic brands — including Ribena, Irn-Bru and Lucozade — have effectively been discontinued…millions of people are having their choices restricted by a bossy government in thrall to the fanatical ‘public health' lobby" Snowdon said.
@ODEONCinemas think it’s ridiculous how I have been charged 25p extra for a classic @CocaCola! I get the whole sugar thing but as an adult it should be my choice as to what drink I would like to drink regardless of how much sugar is in it! #sugartax
@RibenaUK I’ve been drinking Ribena daily for over 50 years, and this bottle will be my last. No reformulation can mask the taste of sweeteners, I cannot drink Ribena again. It simply tastes horrible now. This is not answering consumers needs,this is simply to dodge the sugar tax
Coca-Cola Great Britain said in a statement: "There is no evidence from anywhere in the world that shows taxing soft drinks reduces obesity rates." The sugar tax, championed by British chef Jamie Oliver, appears to have left a nasty taste in many mouths.
