While it's true that Christ is fully spresent under either species, there's another consideration. Several times when I've been traveling and had to find a local church, I've been dubious about the material used for the Eucharist. In several instances, I've been convinced it's invalid matter, incorporating extraneous substances such as honey. In such cases, receiving both species is advisable, in case the bread they used was not valid matter. It's harder for them to mess up the wine.

Actually, according to a priest friend of mine ... don't be so sure.

It seems not a few Catholic churches buy their wine off the shelf from liquor stores. The problem is that most commercial wine contains added sugar and/or preservatives that make it at least illicit and possibly invalid. There really isn't much excuse for this, since there are wineries that specialize in making valid sacramental wine.

This happened to me at a church in the Phoenix area, too.
