If you don't want your drink to taste of plastic then the Specialized Purist WaterGate Bottle could be for you. Whatever liquid you put in tastes the same when it comes out, and the valve works a treat. It's a pricey solution though.
Inside the Purist bottle you'll find an "amorphous silicon dioxide coating" that has been "infused into the inner-wall of the bottle" according to Specialized. It says that this forms a glass-like finish which stops drinks staining the bottle, avoids residue aftertaste and also stops your drink tasting of plastic on hot days.
Switching from sweet energy drinks to plain water with just a rinse in between saw no carryover in taste from one to another, and the bottle has remained completely stain free.
Seeing how far it could go, I mixed a strong vinegar/water solution and left it for 24 hours before rinsing and refilling with water and there was no acidic tang to be noticed at all. So, from a taste point of view the Specialized bottle does what it is designed to.
I like the shape of the Purist, too. The narrow diameter of the neck gives you something to hold to pull it out of the cage and makes it easy to grip when drinking on the fly. The bevelled bottom of the bottle also lets you locate and slide it into the cage with ease.
The Heart Valve is really nice to drink from and seals itself when you've finished so you don't get any spillages on your frame even when riding on rough terrain.
To be honest, there isn't really anything I can fault the Purist for other than the price.
Most people tend to stick to one sort of sports drink and the crossover of flavours between that and water isn't massive in other bottles anyway, so why not go for something like the £7.99 Zefal Sense Pro 65?
I did like the valve of the Purist, but you can get the same option on Specialized's Little Big Mouth bottle (review to come) for just £6.50.
Overall, if a crisp taste to your drinks is the ultimate goal then the Purist is a good choice, as long as you don't mind paying for it.
A bit pricey but keeps your drinks tasting fresh while remaining stain free

Tell us what the product is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Specialized says, "The Purist WaterGate Bottle features an amorphous silicon dioxide coating that's infused into the inner-wall of the bottle. Essentially, this forms a glass-like finish that provides a totally natural, and completely inert, solution to the problem of your drinks staining the bottle or leaving behind any residual aftertaste. This infusion also shields your fresh water from tasting like plastic on very hot days, making it akin to drinking straight from a sparkling clean glass. The silicon dioxide coating is a mere 20 nanometers thick which, for comparison, is less than 5,000 times thinner than a human hair. Meanwhile, the shape of the bottle feels equally perfect both in the hand and in the cage. It comes equipped with our WaterGate Cap, with a self-sealing Heart Valve™ that delivers a high rate of flow with a leak-proof design, even when the valve is open, providing a simple drinking experience."
It delivers on the taste front exactly as Specialized says it should.

Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
