My first 4 cups with this brewer were frustrating... 3 cups of steamed milk (no foam) and 1 cup of cold milk (no foam). I felt like I had tried everything... skim milk, almond milk, whole milk... latte setting, cappuccino setting. I was ready to put the thing back in the box and return it because the cost was too high if all it was going to do was make a single serve coffee. My last ditch effort paid off though! I wondered, why did they give me this lid for the frother? Maybe it serves a purpose in the process. So I used 2% Promised Land milk on the cappuccino setting WITH THE LID ON THE FROTHER. Success! It wasn’t just a little foam or thin either. There was a lot of foam and very thick. So, if you’re having issues with foam and you haven’t used the lid, try it! For some reason, it makes all the difference.
