Cause 1 of 2Milk not cold enough or unsuitable. Source: FAQ: Milk presents large bubbles (1), p. 63
First checkUse cow's milk or vegetable drinks at refrigerator temperature (about 5 °C). With the LatteCrema Cool carafe, only skimmed milk (fat below 0.5%) is marked suitable among cow's milks. With vegetable drinks, "Barista" versions give the best results; if the result is still not as expected, try another brand.
