Taste is ok.. Not my favourite vega product.. Pickle juice works better

I got a sample of this at my local health food store, I've tried a few Vega products and have been really impressed.It comes in a little single pack and you just drop it into bottled water.I mixed up a bottle of this and brought it with me when I went to a local nature/garden festival,it was so hot that day that I thought sipping on this would help keep me hydrated.It also states this is good for sipping on while working out.

It says it is free from sugar and artificial sweeteners which is great.However I could not stomach the taste of this it leaves such a horrible aftertaste in your mouth and I didn't feel refreshed or hydrated.Granted I was not running a marathon or doing a heavy workout but walking a far distance in the blazing hot sun was a test enough for me and this drink did not hydrate me or give me any energy.I should have left the mix out and just brought water.
