Does bubbly froth mean my vinegar batch needs trashed?
I have been making apple cider vinegar at home for a while now. My current batch has white powdery, bubbly froth forming on the top of the bottle and some powder at the bottom. What should I do?
I have sifted all my bottles through thick cloth and re-bottled. I don't see any scummy mother forming. Should I wait longer or should I throw it away? I don't want to do that.
Please help me find a solution. It's been in the process for 8 weeks now.

The foam on top could mean that it is still fermenting... (converting sugar to alcohol. The alcohol eventually turns to acid. the white powder could be "cream of tarter". It is actually just crystallized acid. As for the stuff on the bottom, that is just the spent yeast.

Why is my vinegar foaming?

Access to air is important to the developing vinegar, so make sure it is breathable, while keeping out any unwanted dust. Place the fermenting vinegar in a warm, dark place, out of direct sunlight. (70\xb0F is ideal.) You will see bubbles on the surface that indicate the yeasts are at work.PUT APPLE CIDER VINEGAR ON YOUR FEET AND SEE WHAT HAPPENS!
