Hi Everyone. I'm reasonably new to home brewing and am gradually increasing my knowledge and trying to upgrade my techniques. I would like to have a far quicker way of measuring pre-boil SG and I bought a refractometer and have now calculated the 'Wort Corrective Factor' as 1.0229 from measuring 5 different worts 5 times with it and my hydrometer (as per instructions on various sites). However, I'm not quite sure what I do with the 'Correction Factor'! I assume that I read the BRIX on the refractometer then divide (or multiply?) it by the 'Correction Factor' to give me a corrected Brix reading then convert Brix to SG? Can anyone help? Many thanks.
