If you have a refractometer and have either a conversion program nearby when brewing or have the Specific Gravity range right in the refractometer, I have created an easy one page chart that I use for my brewhouse. I thought I would share with you and I hope you find it useful. Here is the link to the PDF file. You can save the document by selecting the “file” tab on the left side of the page. Select “download Original”.
I have also added a calculator to my website that you can use. This will caclulate Specific Gravity by entering the Brix number. I also have a Brix to final gravity brix reading calculator that will give you the ABV based on Brix numbers. You can check that out here.
