Actually Joan, I don't use the cap. I take the box apart, move the must
around a bit to make sure all the solids are back in suspension,
sanitize one corner of the bag and the hand grasping it, cut a corner
off the bag with a sanitized scissor, and pour into the primary. About
halfway down, I squeeze off the flow and check to see all the solids
are still in suspension , and continue. Of course I do do lift the bag
and initially had Mary help me with that but I've got it down now. You
have to trust the bag to support the must. A few drops have escaped-
the number directly proportional to the number of glasses tasted prior
to the process
