Mass
Prevent mass calculations being recalculated if gravity fields are changed
If selected, mass is treated as 82.1% fermentable sugars, as is true of most honeys. This is separate to attenuation, for convenience when working with mead.
Volume
Prevent volume calculations being recalculated if gravity fields are changed
Mass/Volume Breakdown
Assuming mass is entirely made up of sugar, this panel shows the volume represented by this mass, and conversely, the volume represented by added water. This can be useful when mixing sugar with water to reach a target gravity.
Attenuation
Gravity
This ABV calculation is derived from a formula that is more accurate than the brewer's constant at a range of ABVs, while also being simple to calculate. This means it can be used to calculate ABV from gravity, and all importantly, vice versa.
