Kleen Kanteen Stainless Steel Wide Mouth Water Bottle Review

Average Reviews:

(More customer reviews)I love the design of the bottle but I'm having a problem with some sort of bitter green goo on the lip of the bottle. It appears to be coming from the seam that is just above the threads about 3/16 of an inch below the rim.

When I got the bottle I washed it by hand using dish soap and hand dried it. I put water in the bottle, tested the water tightness of the lid, removed the lid and took a sip. There was a awful, bitter, salty taste and I noticed the green goo on parts of the rim. I thought perhaps it was an adhesive or something (it resembles the remnants of a sticker), so I soaked the bottle (but not the lid) in warm soapy water and thoroughly scrubbed the rim. I licked around the rim and there was no offending taste. I let the bottle air dry overnight.

The next day I put cold water from my fridge in the bottle and capped it. About 15 minutes later I removed the cap and drank some and the foul taste was back. I can clearly see the light green goo on the rim and threads. It was not there before I capped the bottle. It does not appear to be coming from the cap. I suspect that when the cap is tightened it is distorting the seam and this stuff is oozing out. It is gross and I suspect that it is toxic. I am not using much force when capping the bottle, just hand tight and easily removed.

I see one other review here mentioning this problem. I don't know if this only affects some batches of the bottles or what. It looks like this problem might only occur on the wide mouth bottles. You also might not notice this if you didn't drink from the bottle directly (like if you used a cup or a straw). I sent an email to Klean Kanteen customer support but I have heard anything yet (it's been two days).

*Edit* On the third day I received an email from Klean Kanteen asking me to send the bottle in for an exchange and so their QC department could look it over. They thought perhaps the green stuff was residue from the polishing process that got under the rim.

**Edit 2** I received the new bottle and it seems to be fine. I had taken pictures of the original bottle's rim and the new one seems to have a slightly different design. The original bottle had a slightly rounded rim that was a little thicker while the new one has a thinner rim with squared off edges. I don't know if that's a definitive difference or just a supplier variation but I noticed it right away. I'd give the bottle 5 stars if I hadn't had the initial problem, I guess 3 overall considering the hassle. Unfortunately I can't edit the number of stars after the fact.

Product Description:
Dishwasher-safe, eco-friendly, high-quality stainless steel water bottles from Klean Kanteen offer a great alternative to plastic and lined metal bottles. Constructed of food-grade #304 stainless steel, Kleen Kanteen bottles are BPA-free and 100 percent recyclable. An all-stainless steel interior, 18/8 stainless caps, and stainless steel threads mean the bottles won't retain or leach flavors, so you get a fresh, clean, crisp drink every time. Because Klean Kanteen bottles are constructed of food-grade stainless steel, they're not coated with a plastic or epoxy lining like aluminum bottles.
The new wide mouth line of bottles have an opening more than two inches in diameter, which makes filling, pouring, and cleaning the bottle a cinch, and the universal thread design works with most standard backcountry water filters without an adapter. With the Klean Kanteen Wide, you have even more earth- and body-friendly choices. They come in five sizes, ranging from 12 to 64 ounces, and all come in pure, shiny brushed stainless steel. The wide bottles are shorter and more compact than Klean Kanteen Classic bottles but incorporate the same slim design, meaning sizes up to 27 ounces fit in most cup holders. They also come standard with the Stainless Loop Cap, which works seamlessly with the S-Biner, so it's a snap to clip it right onto a shoulder strap or pack.

About Klean Kanteen
Before anyone else was making stainless steel water bottles for personal daily hydration, before the current widespread concern about health and environmental issues in relation to plastics, Klean Kanteen was cobbling together the first Klean Kanteen prototype from items bought at the local hardware store in Chico, California. In 2004, the first Klean Kanteen bottles were released because the company wanted to give people something better than plastic and aluminum--a lightweight, reusable, body-friendly bottle free of BPA; a bottle durable enough to last a lifetime; an easy-to-clean, easy-to-carry beverage container for people of all ages; a bottle that keeps drinks fresh and clean-tasting no matter how many times you refill it; a simple design engineered for function in every way. In those early days, Klean Kanteen shared bottles with people at music festivals, environmental fairs, outdoor recreation events, and other sorts of progressive gatherings.
Klean Kanteen has grown over the past five years from a tiny, upstart company to a leader in the stainless beverage bottle industry. During this time, it's also taken significant steps toward lowering the environmental footprint through consideration and adjustments in every aspect of production facilities and practices. Ensuring office paper is 100 percent post-consumer content, providing hand and dish soaps that are fair trade and eco-friendly, using Energy Star-certified office equipment--these are just a few of Earth-in-mind internal operations choices. This commitment to sustainability also extends to the very beginning of the production process, where Klean Kanteen has increased oversight and conducted third-party audits of factories to ensure they're meeting Klean Kanteena€™s high environmental and fair labor standards.
