 Made specifically for the wine industry, this portable meter tests wines with low phenol contents, such as rosÚ, light reds and whites. Wines should be checked for protein stability before bottling. HANNAH offers a quick test to verify the risk of future protein haze formation. If protein instability is detected, a subsequent test can help define the right amount of bentonite to be added for improving protein stability.

It is important not to overdose bentonite to avoid stripping wine flavor, body, and significant loss of color, especially in young red wines. Moreover, adding only the necessary amount of bentonite to obtain the desired protein stability also saves costs.
