Description

Displays a calculator for determining the decoction volume.  The decoction volume is the amount of mash the brewer needs to draw off and boil to achieve the target step temperature for a mash step.

Use

bulletSelect the Decoction Volume command on the Tools menu.
bulletEnter the target temperature and other parameters required.
bulletRead the decoction volume from the display at the bottom of the view.

View Description

bulletTarget Temperature - The target temperature for the mash step.
bulletStarting Water Volume - The total amount of water in the mash at this step.
bulletWeight of Grain - The total amount of grain in the mash at this step.
bulletStarting Mash Temperature - The temperature of the mash before the decoction.  Usually this is the temperature of the mash from the previous step.
bulletMash Tun Weight - If non-zero, the calculator will attempt to adjust the decoction volume to account for the thermal mass of the mash tun.  Leave as zero if you wish to ignore the mash tun temperature adjustment.
bulletMash Volume to Decoct - The amount of mash you will need to draw off and bring to a boil to hit the target temperature.
bulletWater/Grain Ratio - Simply the amount of water divided by the total weight of grain.  Used to gauge the thickness of the mash.  For decoction mashing, a thin (high water to grain ratio) mash is the norm.
