Argo Tea®, the Chicago-based premium tea brand known for its all-natural tea-based signature drinks and loose-leaf teas, is partnering with Whole Foods Market to launch a line of ready-to-drink (RTD) cold brew single estate bottled teas into the retailer’s stores nationally. The release of the RTD line follows a successful test of the handcrafted single estate cold brew teas in the company’s Argo Tea cafés last year.
