 Flavoured beer Spec ification  
0. FOREWORD  
Flavo ured beer is an alcoholic beverage made from alcoholic fermentation of sugars 
derived mainly from malted  and/or unmalted cereal grains and/or permitted adjuncts  
with additional of  flavo urings, essences and/or plant extracts . It is common alcoholic 
beverage in the country. The beer industry is expa nding very fast to cater for the 
increasing demand of the commodity.  
This Tanzania standard was prepared to ensure  the safety and q uality of  flavo ured beer 
produced and/or traded in and outside the country . 
In the preparation of this Tanzania Standard, a ssistance was drawn from TZS 56 Beer 
Specification published by Tanzania Bureau of Standards and flavo ured beer 
manufa cturers . 
In reporting the result of a test or analysis made in accordance with this Tanzania 
Standard , if the final value observed of calc ulated is to be rounded off it shall be  done in 
accordance with TZS 4 (see clause 2) . 
 
1. Scope  
This Tanzania standard  prescribes the requirements , methods of sampling and test ing 
for flavo ured beer  intended  for human consumption .
