Unlike other denominations, catholics take the communion materials as the blood and the body of Christ Literally- technical term is "transmutation" as the priests convert the materials. As far as I know, most other denominations use it more as a symbol. My father told me that in Chapel of the holy spirit (anglican low church in potong pasir), the pastor would have to quietly drink up the leftover wine after every communion service rather than throw it away.

I suppose wine couldn't be packaged- or the gift shop would need a license for the sale of alcoholic beverages (guffaw)
Though i have misgivings about the existence of home communion sets

First book in harry potter series is "Harry potter and the philosopher's stone" not sorcerer's stone- philosopher's stone is, historically, the material sought by alchemists. A sliver of it dissolved in water gives the draught of immorality, oops, immortality. It also turns lead into gold, when a small amt is mixed into the cauldron. Chemical "transmutation" (in the name of the pun, no offense intended)
