Coca-Cola has today reported better-than-expected quarterly revenue, boosted by strong demand for its zero-sugar drinks and Coca-Cola Plus Coffee, a blend of its traditional soda and coffee. 

Faltering demand for sugary drinks has forced the world's two largest beverage makers, Coca-Cola and PepsiCo, to roll out low-sugar drinks.

The two companies have also diversified their offerings into coffee, tea and bottled waters to boost sales.

Coca-Cola has been rolling out new offerings such as Coca-Cola Plus Coffee as well as drinks in small packs that command higher prices and are more appealing to consumers. 

It also expanded its coffee business with the multi-billion dollar purchase of Britain-based Costa Coffee last year. 

Volume in sparkling soft drinks rose 2% in the quarter, driven by double-digit percentage growth in Coca-Cola Zero Sugar as well as Coke and Sprite in North America. 

Organic revenue climbed 5% during the quarter, above the average analyst estimate of 4.3%, according to five analysts polled by Refinitiv. 

Coca-Cola also said it now expects full-year organic revenue growth excluding currency fluctuations, acquisitions and divestitures to be at least 5%, from its previous forecast of 5% growth. 

Its net operating revenue rose 8.3% to $9.51 billion in the third quarter ended September 27, beating the average analyst estimate of $9.43 billion, according to IBES data from Refinitiv.  

Excluding items, Coca-Cola earned 56 cents per share, in line with estimates.
