Welcome to oat milk country.
By the numbers: About 38.2% of Arizona coffee orders made using Square payment systems in May include oat milk, per company data.
- Only nine states and Washington, D.C., had a higher share.
- Oat milk was the top dairy alternative for coffee drinkers in the U.S. and Canada — included in 33% of all orders in the U.S. and Canada.
- It can be a relatively pricy add-on but the cost has dropped slightly this year, going from 67 cents in January to 65 in May.
Yes, but: While Square's research crowns oat the most popular dairy alternative, there are signs the plant-based "milk" boom is fading.
