I don't use either of them normally but Sinatin is oak extract, you
might want to put in a third of that and taste it, then decide if it
needs more. Glycerin goes a long way too, it adds body but can also
add sweetness. In other words, i would add them slowly if at all. I
don't know what kind of wine this is but most seem to like oak.
