Determination of the capacity for foam to cling to the side of a glass
Beer and beer-based beverages
The measurement with the NIBEM Cling Meter (fig. 1) is normally performed immediately after the NIBEM foam stability measurement and serves to provide additional information on foam quality.
After the preset timer has expired, a scan head is introduced into the Haffmans standard glass while the glass is rotated slowly at a fixed level, in order to ensure that the foam has collapsed a minimum of 48 mm. An LED on the back of the scan head emits light. The diffused light, which reflects off of the inside of the glass, is read by a sensor and recorded.
