Simple question and I am sure there is a simple answer....

If I put some sugar in (say 1lb) and then after a few days how do I
measure the density of the must? the bubbles make the must not unlike
coca-cola and when put into a hydrometer the bubbles stick to it and
make it rise upwards. How do I get an accurate measure (or even a
rough one)?
