- HEB Original Cola
- Safeway Select Cola
- RC Cola
Safeway Select Cola performed best overall. Unfortunately, I can no longer find it at the Randall's stores where I originally bought it.
I administered this test to only a few people (about six, if I recall correctly), so take the results with a grain of salt. But chalk this anecdote up as another example of how customers have all sorts of prejudices that interfere with knowing what they really like.
