Muffin Top

Some people think this is a muffin top, and it is.
some might consider this a different version of a muffin top

this is a winemaker's muffin top

These are pictures of my fermenting apple juice in a variable capacity tank. The first day or two it just rose high like a yeast bread and the surface bubbled just a tiny bit. Now it has large clear bubbles covering the surface and extending far and wide across the tank, and smells divine. Mmmmmmmmm.
