In an attempt to get a little more control over my brewing, I have been looking my refractometer readings during the brewing process. Now that I have worked out how to calibrate my refractometer, this has turned out to be easier to do that I thought!
Here are the refractometer readings for brew 63 – a hoppy pale ale. With a correction factor of 0.96 (which I calculated previously – see here for details), the SG of 13 Brix equals 1.055. Spot on the predicted target SG for this brew! I used the online calculator at Brewers Friend to sort out the numbers for me!
| Brix reading | |
| Mash after 30 mins | 12.5 |
| Mash after 60 mins | 15.0 |
| Mash after 90 mins | 15.6 |
| Mash out (100 mins) | 16.0 |
| Wort (pre boil, sparge water added) | 12.3 |
| Wort (post boil) | 13.0 |
