We all find it difficult to keep track of the number of times that our wine glass gets refilled. I therefore, propose the following gadget:

It consists of a float, enclosing a small clockwork 'counter' mechanism, not unlike a pedometer. A tiny lead weight dangles from the float on some light gauge nylon fishing wire.

Each time as your glass is refilled, the counter increments. The mechanism is 'tuned' so it only clicks when line between float and anchor moves over a set distance. This will ensure that is not activated by the act of tilting/drinking from the glass, or swallowing the float ;-)

For the fashion conscious, the float can be disguised as an olive or cherry, slice of lemon, combo. The anchor can be reshaped as a coffee bean, tequila worm or similar.

A more superior model might incorporate a hydrometer (in the cocktail parasol stick) to check the strength of the beverage being consumed.

Cheers...
