Not as I expected

I recently found these at the grocery store and thought I would try. I’ve used teabags before to make into cold water beverages but this one is specifically for placement in Cold water. That being said if you follow the instructions on the bottle and let it infuse into 500 mL of water it is very diluted and you can barely taste any of the flavors. I’ve tried several of them now with the same results. If you infuse it into a lesser quantity of water the flavour is stronger although still not quite the same results as just steeping a hot teabag and letting the water chill in the fridge. Not their results I was expecting overall.
