 | Refractometer Units - Refractometer measurements may be in Brix or
RI units. Most common brewing refractometers measure in Brix. |
| Distilled Water Reading - Get some distilled water and take a
reading using your refractometer. If you have an adjustable
refractometer, then adjust your refractometer so it reads zero when
measuring distilled water over several samples and enter zero here. If
you cannot adjust your refractometer then enter the distilled water reading
here. |
| Refractometer Reading - Start with a sample of unfermented degassed
beer wort and take several separate readings with your refractometer.
Average the values together and enter the reading here. Try to be as
accurate as possible as small errors can significantly affect subsequent
refractometer readings. |
| Hydrometer Reading - Using the same sample of unfermented wort,
take several readings with a high quality hydrometer as accurately as you
can. Use the hydrometer tool to adjust for temperature if the reading
is taken at a temperature other than your hydrometer calibration
temperature. Average the readings together and enter the number here
as accurately as you can. |
| Brix Correction Factor - A correction factor for wort based on the
two readings taken above. The default setting of 1.040 is a good
starting point until you can get a more accurate reading. |
