Science: Refractometer Brix to SG Conversion Physics
by John Brewster 4 minutes readThe refractometer is one of the most useful tools a homebrewer can own, but using it correctly requires understanding the physics behind the Brix-to-SG conversion — particularly the correction required when alcohol is present.
Coors Light is one of the beers I’ve analyzed more carefully than most people would expect — because the light beer category, often dismissed by craft enthusiasts, actually represents sophisticated brewing engineering aimed at a very specific product
Smirnoff’s alcohol percentage is straightforward for most expressions but the brand’s enormous product range includes several ABV tiers that are worth knowing.
Absolut Vodka’s alcohol content is consistent across its core lineup but varies in one specific category of products that often confuses consumers.
Blue Moon is one of the beers I recommend most often when someone asks for a craft-adjacent introduction that’s available at mainstream venues — it has genuine Belgian witbier character (orange peel, coriander, unfiltered wheat haze) at a price point
