The global obsession with coffee shows no signs of abating, propelling sales and profits at the world’s most ubiquitous coffee chain, Starbucks.

In the quarter that ended June 28, sales in Starbucks stores open at least a year climbed 7 percent, thanks in large part to a strong increase in customer traffic that Howard D. Schultz, the company’s chief executive, said was equal to 23 million new transactions.

Revenue for the quarter jumped 17.5 percent, to $4.9 billion, up from $4.2 billion in the same period a year ago. Profits grew even more, to $626.7 million, or 41 cents a share, a 22 percent increase from $512.6 million, or 34 cents a share, last year.

“The past quarter stands among the strongest, most remarkable of quarters in the 23-year history of Starbucks as a publicly traded company,” Kevin Johnson, president of Starbucks, said in a phone interview.
