Omso hydration mix. I've read all about it almost a year ago, and then finally found them on sale (during the TdF) and went with two containers: one in each flavor. I was mostly intrigued with trying the Blackberry, but figured I'd get a bottle of the orange just to compare it with the Skratch in a blind taste test. Both Osmo mixes provide a good, subtle taste. You get the taste without being blasted with flavor or sugar - which I find is ideal on a ride. Personally, I find both flavors to be great, but I lean towards the blackberry when I need a pick-me-up or when I'm going for a fun ride. I just prefer it. Orange is such a common flavor and so it's hard to impress me with an orange sports drink. No doubt the blackberry will be ordered by me again. As far as downsides go, the Osmo rarely goes on sale, which is disappointing. I'm a bargain kinda guy. I dislike paying full price for anything. In that regard, Skratch takes the cake. It seems every two months or so, Skratch is on sale, which means when it comes to sports drinks, Skratch dominates on my rides. Plus the wide array (and expanding!) of flavors is encouraging.
Now to that blind taste test: I poured 8 oz of room temperature water in two glasses and labeled one glass "A" and the other "B". I then did the math to figure out how much mix should be used in each glass and then had my brother mix them in random glasses while I was out of the room. The flavor was orange. After sipping from both several times, I found it hard to tell the difference. The Skratch had a more Airborne taste (vitamin product). Not terrible, but it was my first thought. Keep in mind, I've used several Skratch exercise mixes throughout the year, so I had some experience with the taste. Overall, I selected the Osmo during the blind test, but unless it's on sale, my bottles will be full of Skratch.
-Rarely on sale (I'm a bargain hunter!)
-Subtle taste (could be a con for some)
-Not many flavors
