- Hold it with the glass cup uppermost.
- Pour a little wine into the cup.
- Wait until the wine drips from the pointed end and make sure that the thin line of wine in the glass tube is not broken by air bubbles – if in doubt suck the wine through the pointed end of the tube.
- Cover this pointed end with your finger and turn the Vinometer upside down.
- Hold the Vinometer at eye level and remove your finger from the end. The level of the wine will immediately descends in the tube. The reading should be taken the first time it stops.
- Repeat the test 2-3 times to confirm.
If the wine being tested is very SWEET or has not been filtered, an inaccurate result may be obtained. Cloudy wines should be cleared before a reading is taken and sweet wines should be diluted with EXACTLY the same amount of water and the result obtained should be doubled.
Readingsfor white wines may be made easier by adding a few drops of colouring matter such as cochineal, to a small quantity of the wine to be tested. Before putting the Vinometer away, rinse it with warm water.
Do not let the wine dry in the tube or it will become obstructed, however it can be cleared CAREFULLY with 5 amp fuse wire.
This is not a scientific instrument so all reading must be taken as approximate.
