FAQ

Does refrigerated Oat milk weigh differently from room temperature?
Fractionally — cold liquid is about 0.3 % denser than room temperature. For cooking this is negligible; for pastry work, measure at recipe temperature.
Can I swap whole Oat milk for skim at the same gram weight?
For mass yes, but fat content changes flavor, browning and texture. In baking, match the variant the recipe expects rather than the raw gram count.
