Arizona-based dairy firm Shamrock Farms has launched a new cold brew coffee beverage across the US.

After an initial launch in Arizona, the company released its new refrigerated product across major grocery and convenience stores in the country including Publix, ShopRite, Stop & Shop, and Giant.

Shamrock Farms' chief marketing officer Ann Ocaña said: "We're always looking for opportunities to grow and innovate and we see tremendous potential in the rapidly growing refrigerated, ready-to-drink (RTD) coffee category.

"We combined the smooth flavour of cold brew with our farm fresh milk to create a delicious and unique product coffee drinkers will love."

Shamrock Farms' new Cold Brew Coffee and Milk is claimed to be made using 100% Colombian coffee beans, milk, and real cane sugar to provide a smooth and slightly sweet finish.

The new drink is available in Original, Mocha, and Vanilla flavours, which are offered in RTD, on-the-go bottles.

Established in 1922 in Tucson, Shamrock Farms produces protein-fortified flavoured milk products. It manufactures Rockin' Refuel protein-fortified flavoured milk and mmmmilk, which are available in retail outlets and more than 50,000 quick service restaurants across the country.
