While semi-skimmed (2%) and whole milk remain the most common milks in American fridges – stocked by 38% and 36% of households, respectively – 12% of households now keep non-dairy milks on hand (Morning Consult, 2021). This means alt-dairy is now more popular than non-fat, 1% and lactose-free milks. Of non-dairy varieties, almond milk dominates market share (69%), with coconut (21%), soy (20%) and oat (19%) following behind (Morning Consult, 2021).

For many consumers, non-dairy milks are their introduction to plant-based eating. Two-thirds of Americans have tried a plant-based milk, outstripping the 52% of consumers who have tried a plant-based protein (Morning Consult, 2021). Experts suggest that alt-milk’s popularity comes from US coffee chains, like Starbucks and Dunkin’ Donuts, adding almond and oat milks to their menus. The presence of non-dairy milk in these chains means the consumption split between consumers in urban and suburban areas, as well as liberal and conservative ones, remains roughly equal. This partnership-driven approach is a tactic that could be replicated by other plant-based companies – see Game-Changing Fast-Food Concepts for early thoughts on partnerships to promote alt-meats.

While these stats suggest that non-dairy milk is moving mainstream, there’s still growth potential for brands who push consumption beyond coffee and into realms like baking. Similarly, consumers’ willingness to sample non-dairy milks could also translate into an openness to other plant-based foods that slot easily into their diet, like plant-based eggs and cheese.
