But now, a month later, some Starbucks oat milk fans say they found themselves unable to order their new favorite drinks.
Starbucks said Tuesday that some places were out of oat milk, but did not specify the extent of the problem.
“Due to high demand, some customers may experience a temporary shortage of oat milk in their store,” a Starbucks spokesperson told CNN Business on Tuesday, adding that customers can expect the oat milk to be back “soon” without offering a specific time frame. In the meantime, they might consider swapping soy milk, almond milk or coconut milk instead, the company suggested.
The coffee chain has taken a look at its oat milk line as consumer demand for plant-based milk substitutes continues to grow. Sales of oat milk in the United States have increased 138% in the past year, according to data from Nielsen.
“Probably the most dominant behavior change in consumer behavior is this whole shift to crop production,” Starbucks CEO Kevin Johnson said on a January call with analysts. “This is why we have introduced all alternative milks, whether almond milk, soy milk [or] oat milk, ”he says.
Oatly also caught the eye.
Starbucks and Oatly did not say whether the supply constraints were directly related to the temporary shortages some Starbucks sites face.
