Wine. You taste (and often with quite a bit of complexity - from the flavonoids), smell and even feel texture in your mouth. I usually don't drink anything other than dry wines as I can't stand any sweetness. I can't say I've ever tried dealcoholized wine but i imagine the fractional distillation process would likely not do the wines any favours.

As for soda, iced tea, coffee and sparkling water, I don't consume much sugar or other sweeteners (says the person with Kgs of fresh honey in the garden and buys dozens of Kgs of sugar to pour into wooden boxes in the same garden) so that's off except for unsweetened water (installed a chloramine filter that make the tap water much, much better). I bought two 6 packs of 710 ml (i.e., equivalent of 2 cans) Coca Cola in plastic bottles and was wondering why they were flat last year. I guess buying them 3 years ago doesn't help. Great for consumption during bike riding though.
