Brewed a Scottish Ale today. Everything goes great according to recipe. All numbers add up during mash, sparge, boil, etc. OG is to reach 1.077, refractometer reads just where we are suppose to be. Start cool down and rack into primary, checked OG again and refractometer is now reading 1.074. What would cause lower reading on a refractometer that has ATC?
