Don't be surprised if a trip to Starbucks' drive-thru for an oat milk latte leaves you with an almond milk latte instead. Recently, Starbucks rolled out Oatly products to all of its stores after recognizing that the world’s coffee drinkers are losing interest in dairy creamers. The coffee chain launched the oat milk last month and now its locations are facing a shortage due to the volume of orders including Oatly. Starbucks saw overwhelmingly high orders for oat milk products, and its locations nationwide could not match the soaring demand. “Due to high demand, some customers may experience a temporary shortage of oat milk at their store,” a Starbucks spokesperson told CNN Business, adding that the oat milk shortage will end soon.
