To calculate the estimated alcohol content, you need to measure the original gravity (OG) and final gravity (FG). As soon as these values are stored in the batch all alcohol calculations are done automatically.
Carrying out the measurement step by step:
- Select your desired unit of measurement: Go to ’Settings’ and ‘Measurement Unit’ and choose SG 20/20.
- Go to ‘Batches’ to create an EasyDens batch to store your measurements.
- Carry out the original gravity measurement and save the measurement value to your batch.
- Open the batch and tap on the measured value in the ’Readings’. A new window is opened. Select as ’Type of reading’ ’Original gravity’. Tap on ’Save’. Now this value is saved as your original gravity value.
- Take measurements of your wine during fermentation at regular intervals and save the measurements to your batch. The fermentation curve is graphically displayed.
- To view the estimated alcohol content, open the batch and tap on the last measured value. A new window is opened. Select as ’Type of reading’ ’Final gravity’. Now this value is saved as your final gravity value.
TIP: There are 3 different calculation formulas available for calculating the estimated alcohol value: Standard formula, C.J.J. Berry Method and The Hall equation. By default, the standard formula is activated, which is suitable for most types of wine.
To change the formula for your alcohol calculation:
Go to ’Settings ’ and ’Calculations ’.Here you can choose between the three calculation formulas. The selected formula is applied to all batches.
TIP: It is also possible to add a value to the list of measurements manually. To do this, go to ’Readings‘ and tap on the + symbol. A new window opens. Type in the measured value, temperature, date and time and type of reading. The value will then be automatically added to your list of measurements.
