Do you know what is in Sparkalloid? I'm very hesitant to use "proprietary"
products with "secret" ingredients. They may work fine (pun not intended),
but I don't want (e.g.) clam shells and possum guts in my wine, even if I
can't taste it. At least I know what's in bentonite, egg whites, tea, and
oak.
