This method describes how to evaluate hoses, particularly beer hoses.
Hoses which are used in the brewing and food production industries
New hoses and/or those manufactured using unsuitable materials can bring about a change in the aroma or the flavor of the liquid passing through them. Pieces of hose are placed in a test medium of either beer or 96 % alcohol. After a defined period of time, the test samples are tasted and compared to control samples.
