HYDROMETER How to Add Sugar Properly
2,7 grammes of sugar gives 1 hydrometer (with Oechslescale) degree in
1 litre of liquid.
17 grammes of sugar gives 1% of alcohol in one litre of wine.
Wine yeast only tolerates 17-18% alcohol, after which it rests.
A reading of over 90 Hydrometer (with Oechslescale) degrees at the start or
75 degrees during fermentation can stop the process.
|+80 degrees||+40 degrees|
Proceed as follows:
Start the fermentation (with Oechslescale) at approx. +80
degrees (4 kg sugar in 20 litres).
When 40 degrees has been fermented (the hydrometer reads 40 degrees),
add the remaining sugar (about 2 kg).
