Do you use this corrected value of Brix also in the calculation of de final gravity?Anonymoushttps://www.blogger.com/profile/05543613138283690213noreply@blogger.comtag:blogger.com,1999:blog-5929711518318385015.post-55856136284296108402012-10-25T20:39:14.002-03:002012-10-25T20:39:14.002-03:00Sorry, my mistake - yes, a malt solution will meas...Sorry, my mistake - yes, a malt solution will measure about +4% so we want to REDUCE the Brix by about 4%, so divide by 1.04 (or multiply by ~0.96 to get similar results).

The refractive index for maltose is slightly different than sucrose - also, there are other non-sugar bits in wort (which would differ from brew to brew) that also affect refraction. You can calculate this difference by comparing your refractometer with a hydrometer; you'll likely find it's somewhere between +2 and +6%.

A wort correction factor must be applied to the Refractometer's Refraction Index prior to calculating a Brix or Plato value.Low Tech Brewerhttps://www.blogger.com/profile/01114247725865836979noreply@blogger.com
