Here we're going to talk a little bit about the 2 calculators that come with the recipe currently.
In the standalone carbonation calculator, you have to choose a style to display the min-max carbonation levels. You'll also have to choose the volume of beer.
If your recipe already has volumes and a style selected, the recipe bottle carbonation calculator will already include these fields. All you have to do is choose the type of sugar you wish to carbonate with, and it'll show you how much you need for the min or max displayed volume of CO2. If you prefer to dose your bottles with sugar, it'll also show you how much you need for each bottle.
If you want to put a custom CO2 volume, just enter it in either the min or max field.
This calculator does 2 things:
Keg carbonation is a bit more complex than bottle carbonation. You'll need to input your line ID and tap height to get the right force carbonation PSI figures. This currently defaults to some standard settings.
The most important thing to know about your line type is the ID (inner diameter) and the OD (outer diameter). Here's a handy diagram to help you figure this out:
Beverage lines come in all shapes and sizes. The currentl list is imperial-centric, but here's the list of what the site currently supports:
Tap height is simple the vertical distance between the height of the tap to the centre of your keg.
You could simply measure the distance between the tap and the bottom of the keg, then the distance between the top of the keg, and divide by two to get this number.
