Vino-O-Meter o Vinometer
The Vino-O-Meter is made of glass with the upper part in the shape of a cylindrical cup and with a narrowing of the lower tube ending in the shape of a conical pipette.
Instructions for the use
1. Fill the upper metronome cup with a small sample of the wine to be measured
2. Hold the vinometer in an upright position until several drops of wine drip from the bottom of the pipette
3. Invert the instrument with the shape of the cup facing downwards until its contents are emptied and watch where the wine is retained in the scale column.
