Brieftons Borosilicate Glass Water Bottles: 6 Pack, 18 Oz, Stainless Steel Lid, Durable, Crack & Heat Resistant, Best As Reusable Drinking Bottle, Sauce Jar, Juice Beverage Container, Kefir Kit

Functional: These Brieftons Borosilicate Glass Bottles are amazing, and I'm glad I took the chance that they would work for the second fermentation of kombucha. Kombucha bottles need to be leakproof and very strong to hold up under the pressurization of the second fermentation, when kombucha develops its fizz and fruit flavor. These bottles meet those qualifications and work perfectly for kombucha.Beautiful: Function is a necessary thing, but beautiful is just appealing. The colorful image on Amazon of these Borosilicate glass bottles is what really appealed to me enough to purchase these, instead of lower priced bottles. These bottles are crystal clear and elegant looking, and my fruit-fermented finished kombucha looks just as cool, colorful and inviting as the image for this productEnjoyable to Use: The enjoyment of using these bottles is so worth the higher price. They're noticeably lighter in weight than the GTs kombucha bottles I've used in the past, and yet their capacity is 2 ounces more. They're comfortable to hold, and they feel smooth and almost silky in my hand.Replaceable Leakproof Caps:I looked a long time for the perfect kombucha bottle, and replaceable caps was a requirement. Replaceable caps (2-pack) for Borosilicate Glass Bottles are available on Amazon for about $2 per cap.CUSTOMER SERVICE? AMAZING!!!:Brieftons Borosilicate Glass Bottles are beautifully packaged and have both a user guide or a customer service contact email listed inside the box! Well, I had an issue with a leaking cap and decided to test it out before writing a review.The following morning, Mr. Brieftons himself responded and apologized. He explained that they had received a bad batch of caps but thought they had caught them all. He said the proper caps are leakproof and said he was sure I would be happy with them. He priority mailed me 6 new caps and asked me to let him know how they worked for me.My Response:Jun 28, 6:58amHi Thomas:Thank you so much for your prompt attention to my leaking cap. You were exactly right! I do love them!I received the new caps today, replaced all the old caps, filled all the bottles with water, turned each one upside down and shook it with a vengeance. Not a drop of liquid leaked!!!! So happy with these sleek, lighter weight bottles and leakproof caps for my kombucha.SandiMr. Brieftons Response:Jun 28, 10:25amDear Sandi,Thanks for your update, and I'm very glad to hear the new caps work well for you!I hope the glass bottles will serve you well in your kitchen!I appreciate your kind understanding and patience while we resolved the issue.Thanks and have a good day!Thomas Brieftons

These bottles are made of borosilicate glass, which is stronger than “regular” glass. This type of glass is used in laboratories because it resists thermal shock and chemical attack.For example: I used to prepare green tea in a teapot or Pyrex measuring cup, then pour that into a flask to put in the fridge. Now I make my tea right in one of these bottles and when it’s cool it goes in the fridge.The bottles are tall and narrow and several of them on the shelf. Which is good because I use them a lot, and these days my fridge is always filled to capacity. They take up so little space. They are perfect for making salad dressings and vinaigrette. Neither the glass or the silicon cap liner absorb taste or odor, unlike plastic bottles.I don’t like drinking out of plastic. Small amounts of plastic and chemicals leach out of all liquids in plastic bottles. It’s only a trace amount and well below “safe limits”, but why consume any plastic if you don’t have to? These lab grade glass bottles don’t contain any synthetic substances that could leach into their contents, no matter if I’m using them for water, tea, oils, acids, you name it.The bottles would be easier to clean with wider mouths, but it’s not much trouble to use a brush. I also put a bottle in the flatware holder of my dishwasher as a test - I was skeptical that such a tall, narrow bottle would be properly cleaned and/or rinsed, but it came out sparkling.TL;DR - these are excellent bottles that can replace plastic containers, are stronger and more shock-resistant than ordinary glass, and have a tall, narrow profile that takes up little space on a refrigerator shelf. Highly recommended.

I just got my box of bottles. I was so excited because I've been using empty kombucha bottles for my smoothies. These looked great online. I read the bad reviews, but I figured that I'd give these bottles a try anyway. Big mistake. Firstly, the glass feels like it's very thin...far thinner than my empty kombucha bottles. I feel like I could break the bottle simply by setting it down. (Think "delicate martini glass" thin...not "every-day glass.") But the real problem is the lids. I noticed right away that all of the lids (even the ones on the bottles that I hadn't yet taken out of the box) seemed to be "wonky"...as in, they didn't seem like they were screwed on tightly. Imagine if you have the wrong lid for a bottle...you might be able to turn it if it's the right size, but you might never be able to get it "straight." It might always be a little crooked if the threads aren't the same. That's exactly what you have with these. Every single lid was the same. Not only that, but the lids felt like I could literally crumple them in my hands...super thin and flimsy. It was obvious that the lids...no matter what I did...would absolutely NEVER seal properly. Just on my own little trial over my sink, I couldn't get them sealed. If you throw this in a purse, you will definitely have a purse full of wet stuff. :( It took me all of 30 seconds to decide that I'm definitely not keeping these. I ended up buying a different set of bottles that have plastic lids and are shaped more like a "jar." Those are SOOOOOO much better!

I have purchased this with the silicone sleeve. Bottles are nice and clear. Putting sleeves on was little tricky, because of the tight fitting, though I managed by using soapy water on the surface. Also I can wash the bottles with sleeves in the dishwasher. These are very nice bottle.I have changed the rating 5 to 4. I like the bottle is nice and clear, but this is not leak proof. I was using it upright most of the time and no problem (of course) but then I had to shake the bottle to mix something. Leaked.Based on other reviews, I am wondering there may be some fake sellers. Just watch the seller as "Brieftons" then you will get this product!
