purist bottle technology
The plastic taste imparted by the usual bicycle water bottles is that is discouraging not only because of the chemical flavor but also the thought of it doing harm to the body on a cellular level. For this reason, bottle alternatives seem worthwhile. A stainless steel bottle setup such as a sport cap klean kanteen with a specialized rib cage 2 holder seems like a good solution, though I do miss the ability to squeeze a drink rather than needing the suction. As such, looking into the specialized purist water bottles, I saw their hype about how their "purist technology naturally shields the inside of your bottle .. exactly the same way a lotus leaf shields itself to maintain its purity. Technology truly inspired by nature." The bottle interior is has a five micron coating of silicone something or other. Does anyone have information on the nature of this coating technology, the credentials of its purity and just how much the biomimicry claims are valid?

What a load of marketing nonsense. A lotus leaf's "purity"? LOL. It's totally natural for a bear to maul and kill a person, but it certainly isn't healthy (for the person).

I've always thrown a bit of juice, even a slice of lemon, into my water. Grapefruit syrup is quite nice. Add ice cubes if it's really hot.

I've worn out nearly everything cycling-related I've ever bought. My current CX bike was built out of the remains of my first CX bike (broken frame) and by now nearly none of the original parts remain. It is my Ship of Theseus.
But I've been using the same pair of Camelbak Podium Chill water bottles since my second or third bike ride. Their logos are all worn off, and they have more than their fair share of scratches. Never has there been a plasticky taste to the water, not once, and never thought about whether or not they're imparting anything into the water. I've refilled them from hose spigots and MUP water fountains. If there had been any reason for worry, it would have been that.
I guess the takeaway is don't buy $3 water bottles. Anything by Camelbak or Polar isn't going to change the taste of the water. Can't speak to others.

I'm doing a self study on the effects of plastics to a human on the cellular level as we speak. Good so far but if you never hear back from me you can probably guess the outcome.*

much the biomimicry claims are valid?
then it's more opinions than confirmed science,
in that case, a search of a few research documents on the topic , may be in order.
name dropping a simpler response..
I have Sigg bottles, for drinks they have a bonded liner applied,
Another from Zefal , the cap airflow in, lets he water flow out easily..
...

Water taste clean to me through polar bottles. But a stainless container can only be a little better. My bike shop gave me a free bottle that the first time I tried it the plastic taste was utterly horrible. I found it insulting that they would give me such crap.

The Specialized Purist bottles are excellent. Pure water taste, three years later. Even let it sit in the fridge full all winter and in the spring that water tastes just as clean as if I would've put it in there the day before.

Personally I prefer the taste of plastic over chromium

I’d take the Purist lotus leaf reference to mean that the lining of the bottle is extremely hydrophobic, like the waxy coating on lotus leaves, which helps prevent dust and grime from sticking to the leaves, keeping them clean and, in a sense, pure.
I’ve not read the Purist site, but I’d speculate, based on what the OP said, that a type of silicon oxide (SiO2) ceramic coating is bonded to the inside surface of the bottle. One of the properties of these coatings comprised of densely packed, tiny (nano) particles is chemical resistance, so in being bonded on the bottle surface, they inhibit the transfer or leaching of compounds from the plastic to the water.
I have certainly been around long enough to smell water bottles that had plasticky, synthetic chemical odors, and to taste the same in water from other bottles. We know for a fact that plastic formulations can, have, and do leach chemical compounds, some with high estrogenic activity levels like BPA, but many which have not been researched for impacts on humans.
Given what we don’t know about synthetic chemical compounds in the body, and given what we do know about the relationship of estrogens to cancer, it is certainly sensible to take precautions to reduce ingestng those things when possible. To that end, the small cost premium for a couple Purist bottles is the only downside to reducing the risk factor in cycling water bottles.
Couple that switch with a shift to bottled water in glass, and I think one could take some comfort in reducing consumption of water which has steeped in plastic.

Irony being, all the water pipes in modern houses these days Downunder are allowed to be PVC plastic.

Certainly we are talking about modern living, so nothing is universal, easy, or 100% guaranteed. It's all about which lifestyle choices one can afford to make, and which ones they cannot. It would be great if one could decide they don't want to get cancer and just stop using plastic water bottles, but it's far more complicated than that, and I think really boils down to simply moving the "football of progress" downfield by emphasizing the right issues and keeping the gameplay on course.

I think that's just the unpressured drain lines. PVC makes horrible pressure lines for incoming water because it gets brittle after a few years and tends to fail catastrophically under pressure.

There is chlorinated PVC (CPVC), which can be used for supply, and another type of plastic hose called PEX. Old fashioned PVC is typically used to supply main line into house, too.

I don't notice any plastic taste in my water bottles. But I just re-use some gator-ade or vitamin water bottles that are made from that gender converting material that one can find scare stories all over the internet about.
Even if they are completely true, I'm not worried at all because I only fill my bottles just before I ride and the contents are gone in two to three hours. So how much bad stuff could possibly leach from the bottle during that time? Probably not much, and less each time they are used.

This kid...
... just told you to "HTFU"
Seriously. Unless you're getting your water shipped to you in glass bottles directly from the spring, no lotus leaf nanotech hydrophobic bottle is going to make you healthier... at a cellular level.
There was a thread on the gravel forum - guys complaining about bottle nipples getting dusty. $*@# me. I've been mountain biking since the '80s. Before that thread, I'd never heard/read anyone complain about dusty nipples.
Chopper... we need you buddy.
