If you are into wine decanting, this WMF funnel/filter is a must have. My son and daughter-in-law are into wine and wanted to start decanting. I purchased 3 different decanters and this funnel/filter for them for Christmas. I, who knows nothing about wine, noticed the difference. More importantly, my son and his wife noticed a big difference! They used the funnel & filter to pour the wine into the decanter. You could see remnants of sediment in the filter after they poured the wine. The wine had a smoother feel to it as I drank it. It didn't have a slight bite like wines poured straight from the bottle.So, if you are a wine buff and want to improve on the taste and texture of your wine, then add this WMF funnel/filter to your wine accessories. You will not be disappointed.
