One philosophically fascinating aspect of Catholicism is the very strange conception of reality it presents (the incarnation, the eucharist, judgement day etc.).
I do think that if you are trying to think empirically about the relationship between conscious experience and the underlying physical reality, wine provides an excellent practical example. Winemakers manipulate the chemicals they are dealing with in a way that is very sensitive to the kinds of effects it will have on the subjective experience of tasters - this is not an accident.
