Multi-Use Glass Bottles

Hold Everything

Retap creates strong, versatile, and eco-friendly glass bottles. The elongated, retro milk bottle look has (unsurprisingly) won several design awards. Made of borosilicate glass—the same heat- and shatter-resistant type used in laboratories—the bottles are lightweight, dishwasher safe, and won't interfere with taste the way plastic and metal can.

The wide mouth makes it easy to fill, pour, and clean, while the sleek design eliminates edges that could trap bacteria. These bottles can handle hot and cold liquids, and
the caps are colorful, BPA-free, and fit on any size Retap bottle.

Founders Lars Brondum Petersen and Robert Hjernberg wanted a thoughtful, reusable alternative to drinking water from disposable plastic. But these bottles are too beautiful to restrict them to water. Pour in hot leftover coffee and put in the fridge for iced. Use them to hold juices, cream, dressings, and more. Retap is a wonderful way to serve and store beverages and liquids.

    Hi everyone! I'm proud to bring Retap to The Grommet. Our eco-friendly sturdy glass bottles are a great alternative to wasteful plastic. I'd be happy to answer any questions you have!

    Love these! Can you tell me more about the lids and their fit? The description says that they don't leak. Does that mean that the lid stays securely attached, even if placed on its side in a lunch bag?

  • Douglas

    @Terri They are a pressure fit. They don't leak, even in your lunch bag. Stick them anywhere and do not worry that you will find a pool of water like so many of the tops of other bottles. Further, when you actually drink the contents, you only ever touch glass.

  • Kerry

    @Douglas However, in warmer weather/conditions, cold drinks will form condensation! Just wanted to point that out so that it's not packed in a paper sack. It would be a dreadful end to such a great bottle if it were to fall through & crash on the floor/ground.

  • Douglas

    @Kerry That is true that condensation can occur and potentially effect a paper lunch bag. You might consider a reusable bag made from a more durable material with a number of options available found here at The Grommet.

    Do you sell replacement caps in various colors?

  • Douglas

    @Eva Yes we do. They are available on our website.

    I like to add essential oils to my drinking water. However, the oils are usually only added to pure glass containers. Will essential oils eat through these bottles? Is there a lining on the inside of these bottles? Thank you in advance.

  • Douglas
    Douglas – Special Guest
    2/19/2015 12:49 PM

    @Erin No and there is no lining. Just borosilicate glass. And glass is your best material for food and drink. It is safe with no leaching and easy to clean.

  • James

    Have had quite a bit of experience with borosilicate kitchen items and recently purchased some lab supplies for a Science Fair. One thing I do know in regards the glass, if there is even a tiny air bubble created in the forming, the item is exceedingly weakend at that point (a lesson I learned with a beautiful teapot many years ago) and it will break, no ifs, it will. Even the seller of the beakers I bought had a sign on the shelf saying to check for bubbles before purchase. Now this is only a real issue when the glass is pulled/formed thin (not like the usu measuring cups many are use to, though in the U.S. they are now soda-lime ).

    How thick are the walls of the bottles?

  • Douglas
    Douglas – Special Guest
    2/19/2015 12:57 PM

    @James We QC every bottle so it is unlikely that you will receive a bottle with any bubbles and the manufacturing uses a process that is designed to eliminate imperfections and takes advantage of the strength borosilicate glass.

  • Sandy
    2/19/2015 12:52 PM

    This looks AWESOME!! Right now my husband re-uses plastic water bottles, Gatorade bottles, etc, and it's making me crazy!! One question, how easily is it cleaned? The video shows it in the dishwasher. Does that actually get it clean? Other cleaning options?

  • Douglas
    Douglas – Special Guest
    2/19/2015 1:02 PM

    @Sandy Reusing Gatorade bottles is better for the planet but probably not so good for your husband. Visit "The Story of Bottled Water" video or the Environmental Working Group for reasons why. They are easy to clean. Often just a rinse or warm soapy water will do the trick, but you can put them in the dishwasher as well. Glass is very easy to clean and maintain.

    @Sandy, I've been testing the bottles with half and half, milk and juices. I have washed them three ways and all have worked: dishwasher, shaking them with hot soapy water, and scrubbing with a bottle brush. All methods have worked...and I am happy that the cream residue washes off easily. (Half and half is my daily use, and so a "high mark" of cream can develop after a few days--that is what I mean by residue. Hope that makes sense.)

  • Gerald
    2/19/2015 12:54 PM

    I'd love to have some of these but $20 for one bottle seems a bit too pricey for my budget.

  • Douglas
    Douglas – Special Guest
    2/19/2015 1:04 PM

    @Gerald Depending on how many single use plastic water bottles you use, this bottle can pay for itself pretty quickly. Glass is you best material for food or drink. Please watch the "The Story of Bottled Water" video for more detailed information.

  • Laurie
    2/19/2015 1:15 PM

    I agree with Gerald, the price is too high when there are alternatives such as square refrigerator bottles and mason jars already available for much less (about $2.50 for a quart canning jar). Basically, one is paying for design, not function.

  • Gerald
    2/19/2015 1:34 PM

    Plastic water bottles can be used many, many times. The idea that they leach carcinogens is a myth. In your video I see these bottles backed in cases that hold many. What is this about?

  • Douglas
    Douglas – Special Guest
    2/19/2015 1:44 PM

    @Gerald We can agree to disagree about plastic bottles. In respect to the cases, our bottles are shipped in boxes from the manufacturing facility to us and I think this is what you are seeing.

  • Deanna
    2/19/2015 3:51 PM

    I agree that this bottle is aimed for the yuppie set, not for the likes of me. While I enjoy frivolity, you have to buy at least 3 to enjoy the different color caps and, ultimately, why? I will also add that I do appreciate the look and the glass.

  • Evan
    2/19/2015 9:45 PM

    @Deanna - Agreed. I think with any glassware item you get, you normally get a set of 2 or 4 in a pack, yet this Retap idea seems to not be following the normal flow of things... I have no use for just 1 of an item. If I'm going to get an item, I want a set of 2 or 4 or 6 so that I can use them for several things and not just one thing at a time. Just like with any glasses you get at Dillards, Maceys, and other places like that.

    @Douglas - I have been down the 'how many plastic bottles' road with companies like Kor Water and frankly the set up just isn't good. They're fragile to say the least and the cost of replacement isn't worth it. These are supposed to be used over and over and over, yet the cost for one doesn't justify it when they're going to inevitably be damaged either by dropping or whatever, and then you have to replace one and it's another 15-25$ PER GLASS! If the cost of one Retap glass was like 5$ or lower, I could bring myself to justify the cost... but not for each one being a price gouge. I can buy BPA free and leach free reusable plastic water bottles for 5$ that hold 72oz (which is what I drink everyday) and it lasts for months. -- Not saying this isn't a great product, but it's severely over priced when compared with other similar products. Bring the price down and I would be all over this, as would many other people.

    Gerald, Laurie, Evan —For some, you're right, the price cannot be justified. But with the high-quality glass, BPA-free cap, award-winning design that helps prevent bacteria, and a lifetime warranty, the Retap bottles can very easily pay for themselves and look good doing it.

  • Dan
    2/19/2015 1:09 PM

    Are larger sizes (1/2 gallon, gallon) coming in the near future? These sizes seem kind of odd for sure

  • Judie
    2/19/2015 1:22 PM

    @Dan wondered the same thing

  • Douglas
    Douglas – Special Guest
    2/19/2015 1:23 PM

    @Dan We have no immediate plans for larger sizes. Their primary purpose is for drinking and typical beverage sizes are 12 to 20 ounces and we think our 10, 17 and 27 ounce sizes meets the needs for most people.

  • Evan
    2/19/2015 10:01 PM

    @Douglas - Very good point on the sizes here. The 10, 17, and 27 are pretty standard drinking glasses. However one point that the video makes is that you can store larger amounts of liquids, like juices or whatever, in clean and durable glass containers ... so to that point, a 36 or 48oz vessel would be very handy. I know most fountain drinks, and or those shake mix drinks you can get at Smoothie King or make at home are in the 36 to 48oz range. I know I personally have half my cabinets full of those kind of plastic cups, most of which have half of the writing flaking off, but it's just part of it. Larger carafe glasses would be super handy, and I think that was what Dan was getting at.

    Hi Douglas, Are these bottles microwave safe?

  • Kathy

    I have 3 sons. I'd like to buy these for the kids lunch box/backpack. Are these bottles strong enough to stand up to the wear and tear of school ages boys. Backpacks in my house are often thrown, stepped on tossed on to hte floor. I'd hate to break such a nice bottle.

    Are these bottles recommended for rough housing boys?

  • Douglas
    Douglas – Special Guest
    2/19/2015 1:48 PM

    @Kathy While the bottles are very strong and glass is your best material for drinking, you might want to consider a food grade stainless steel bottle for active boys. The Retap bottles would be perfect for them around the house.

  • Judith

    What material are the caps made of?

  • Douglas
    Douglas – Special Guest
    2/19/2015 2:03 PM

    @Wayne Our tops are made of thermoplatic elastomers (TPE). With our bottle design, when you actually drink the contents, you only ever touch glass.

  • Larry
    2/19/2015 2:34 PM

    Why the oddball sizes? They should be in standard 12, 18, 24, and 32 ounce sizes.

  • Douglas
    Douglas – Special Guest
    2/19/2015 2:50 PM

    @Larry I guess you can blame the Europeans for the oddball sizes. I use the 17 ounce every day and the missing ounce has never been an issue.

  • Ralph Morgan

    I have been transitioning to glass for storing leftovers and everything in the fridge. I also Nurture probotics with Kefir grains for carbonation in the fridge. Do you have a cap that can support carbonation?

  • Mike
    Mike – Grommet Team
    2/19/2015 3:44 PM

    Hi David, Douglas can correct me if I'm wrong, but I believe the lids on the Retap bottles do support carbonation.

  • Douglas
    Douglas – Special Guest
    2/19/2015 4:23 PM

    @Mike While I am unaware of a specific test over the long-term for carbonation, I can tell you for short periods of time it will not be an issue. And based on the nature of the pressure fit top, I suspect you will not have any issue over the long term.

  • Dawn
    2/19/2015 4:05 PM

    I would like to know if they will fit in the cup holder in my vehicle. What is the circumference of the bottles at the widest point?

  • Douglas
    Douglas – Special Guest
    2/19/2015 4:15 PM

    @Dawn The small and medium definitely will. Depending on the vehicle the large can. Diameters are 2 5/8, 2 7/8 and 3 1/2.

  • Nathan
    2/19/2015 4:39 PM

    Please offer a food or better yet pharmaceutical grade silicone top. That is a deal-breaker for me with this.

    For those complaining about price, you can keep using cheaper, harmful alternatives, but keep your criticisms of price to price, and don't smeark the demographic willing to pay for something that's, in fact, a better product. Borosilicate generally runs more expensive. That's because it's not average glass. If it were, it would be the same commodity and the same price. You're paying for a lot more than just design. The Grommet exists because people are willing to see past their fiscal noses. Anyway, pet peeve, as you can tell.

    I absolutely love these. I bought them for Christmas presents. My husband has his at work. We use them upstairs and downstairs at home. Each of my kids have one too. They're fun to drink! No straw needed. Because they are fun, you tend to drink more than was usually happens. Looking for ways to put a larger one in the frig.

  • Suzanne
    2/19/2015 7:50 PM

    The description indicates it can be used for hot and cold liquids. If you put hot tea in it, does the glass become too hot to handle?

  • Evan
    2/19/2015 10:06 PM

    @Suzanne - Dan can correct if I'm wrong, but I would guess that hot liquids would be a little unpleasant to handle in these containers when filled fully. I'm not seeing that they are double-walled like some Starbucks glass mugs which would help with temperature. So I would suggest not filling it full with hot liquid and just handle the top part to prevent the unpleasant side effects.

  • P.K.
    2/20/2015 7:58 AM

    like the look & the glass reusable utility aspects, but the price for a plain glass caraf; even with the cute colorful cap, is ridiculous.....sorry will look else where
