A simple method for accelerated determination of apparent extract during the fermentation process.Peer-reviewed article

J. ŠAVEL

The article deals with a simple method which has been developed for accelerated determination of apparent fermentation degree which must be known to control the fermentation process. The method is based on a simple relation existing between apparent extract and refraction, provided the beer strength remains at its initial level. For the initial strength p- 11.50 the formula has the following form: m = 0.3830r - 11.7129. The error does not exceed 0,1 % [ in terms of mass].
