Coca-Cola Co has beaten an analysts' estimate for quarterly profit and raised its organic revenue forecast for the full year, driven by demand for zero sugar soft drinks and innovations, such as the Coca-Cola Plus Coffee.

The world's biggest beverage maker has been responding to changing consumer tastes by moving beyond traditional soft drinks and offering beverages that are lower in sugar or come in new flavors.

Coca-Cola bought Britain-based Costa Coffee for $5.1 billion and recently rolled out ready-to-drink coffee in cans in the UK and a coffee-based soft drink in several markets.

The company plans to launch the beverages in other markets this year.

The beverage maker reported a 6% rise in second-quarter organic revenue, a keenly watched metric that gives sales growth excluding acquisitions and currency fluctuations.

Net revenue rose 6.1% to $10bn in the second quarter ended June 28, a touch above the estimate of $9.99bn, according IBES data from Refinitiv.

Net income attributable to the Atlanta, Georgia-based company rose to $2.61bn, or 61 cents per share, from $2.32bn, or 54 cents per share from a year ago.

Excluding one-time items, the company earned 63 cents per share, 2 cents above Wall Street's estimates.

The company said it expected organic revenues to grow 5% in the whole of 2019, up from its previous projection of a about a 4% rise
