In the last two weeks I have purchased one six-pack of Orabelle and one six-pack of Colette. I have opened five of the six Orabelles and two of the six Colettes and, thus far, each bottle I have opened has been slightly flat with very little seal on the cap. In all instances, taste has been good, i.e., not oxidized, but mouthfeel has ranged from undercarbonated to flat. I have read reviews and people are mentioning good carbonation, so I'm surprised by what I have experienced. Anybody else notice this?
