Below you will find Staffordshire Brewerys ABV Testing Procedure for Beers & Cider
high specification equipment
The equipment used for the ABV test is an Anton Paar DMA 4500M coupled with an Anton Paar Alcolyzer Beer ME. These instruments are density and concentration meters that have been developed to combine the highest precision with ease of operation and robust design.
The equipment meets all the requirements of applicable sections of relevant EU directives in design and type, and is used and accepted by HMRC Duty regulations. HMRC Excise Notice 226 paragraphs 12.2, and 30.3.
quality testing process
The sample is introduced into a U shaped borosilicate glass tube that is being excited to vibrate at its characteristic frequency. This frequency changes depending on the density of the sample which can then be calculated. In binary mixtures the density is a function of its composition therefore the composition of the mixture can be calculated. This is also true for mixtures of two major components and some additional components which are present in comparatively small concentrations.
For all testing, please send in at least 100ml or beer/cider.
