This is a bit of a random project I am looking into. Recently a product was released called the beer bug. It measures the density of beer by tracking the weight of a submerged buoy. They calculate change in density based on changed in weight and then calculate % alcohol (ABV) from that.
Normally specific gravity readings are taken before and after fermentation with a hydrometer. As the sugar is consumed by the yeast it changes the density. This is how you can obtain ABV.
Both of these methods seem clunky and difficult to get a digital reading that you could track on an LED screen. Can anyone think of another way to measure density? Is there a way to measure alcohol content or sugar concentration directly?
Thanks
