How far into the test were you before you got to the Palma? In my beer drinking days, after the 3rd it didn't matter if I was drinking panther pee.
I spaced it out about an hour between beers. Then just to make sure I was accurate, I went back to the store a couple of days later and bought more Palma Luocas and learned that I wasn't wrong. BTW, I also ran taste tests against Kirin beer. I like Kirin beer but Palma Luoca still came out ahead when I compared the two.
