Selecting ‘Target’ on the Additive Template will cause any additions created from the template to calculate the Additive Amount value that will result in the Metric to reach the ‘Target’ value.
Only Additives that have an associated Metric can have the Target Rate selected.
Default Add Rate vs. the Target Rate
The Add rate is calculated only by the rate amount i.e. 25ppm of the wine’s volume. Where the same target rate(25ppm) will first find the current Additive/Metric rate (i.e. 10ppm) and work out the amount of additive needed based of the difference in rate (i.e. in this example 25 – 10 = 15ppm).
In this example, a ‘target rate’ of 25ppm is the same as an ‘add rate’ of 15ppm given that the Wine has a current rate of 10ppm.
Note: The addition will be switched to an ‘Add’ rate if ‘Target’ is selected but no current rate can be found for the selected wine.
