OK - I promised that i'd review this product if he sent me some (he did)

It *does* seem to smooth out the taste of a cheap pinot noir , for example ... more fruit/soft berry emerged from what is otherwise/usually pretty metallic and sharp French pays d'oc Pinot taste .....

I also used it with an American pale ale beer and got similar result - less bitter hop bite (i do not like the hop-bitterness that some people do ...)

I am not sure if it was merely the power of suggestion at work and my expectations OR a scientific change that occured molecularly ...

It's worth a try if you can't stand the caustic tannic bite of red/white wines (I cannot) ....
