I think it tastes pretty good. I wouldn't want to do it all the time, but occasionally it's a nice change of pace.
I like them all, but if I am at the store I'll usually pick up Corona or Dos Equis along with a couple limes.
glynch, you may know this, but a "barril" you spoke about just means a keg, I know. It is or was an advertising thing. It was sold in brown bottles. It wasn't the corona sold in the white bottles here in the US. In fact do they even sell that Corona in Mexcio at all? Hey don't forget Bohemia. It is excellent and the best of the non-amber , non dark beers IMHO.
