Folks,
A bit of a testimonial..
Reduless is a WONDER!
I had two batches of wine (a 2010 brunello, and a 2011 blend) that developed a overpowering "burnt" aroma. Research suggested that this is either ethyl mercaptans or perhaps caused by the type of toast on the oak used (over oaking).
To tell the difference, it was suggested that I do a simple bench trial using raw copper. I took rather thick guage copper wire, scrubbed it with a scotch brite pad, then swirled the wire in a test beaker of each wine for about 10 minutes. There was a distinct improvement, thus proving that the problem was ethyl mercaptans.
I then did a bench trial of 1 liter of wine and treated it with the reduless. It did not take 10 minutes! The off oder was gone immediately!.
I had in the past used copper sulfate, but it never seemed to work this well and this quick. Reduless is a dried, dead culture of yeast that was grown in a high copper environment. It is a much safer and effecient delivery of copper into wine than using copper sulfate. The recomendation is a racking after 3 days of treatment to avoid imparting too much copper into the wine.
I treated my main tanks over the long weekend, and racked yesterday.
What a wonderful product!
