Jheppbay Glass Swing Top Beer Bottles - 16 Ounce (6 Pack) Grolsch Bottles, with Flip-top Airtight Lid, for Carbonated Drinks, Kombucha, 2nd Fermentation, Water Kefir, Clear Brewing Bottle.

They keep the gas in.

Perfect for bottling home made cider

Excellent "Grolsch" bottles, well made, thicker at the base and the shoulders with a well fitting cage and stopper giving a good airtight seal. Expensive at £16.99 for six but worth it in the long run, they can be cleaned and re-used repeatedly and don't break easily. Arrived well packaged in foam to prevent breakages in transit. Would buy again. 5 stars.

These bottles are very effective, though the locking mechanism on the top is very tight so could be a problem for those with dexterity issues.

Really struggled to find bottles online that where good for kombucha and carbonation, and then found these and they are great! Very sturdy and great for what I needed them for, would recommend!!

Superb for my craft gins .

Good size and well made

Awesome product for kombucha.

Not what I ordered. The style, shape, and dimensions of the bottles are NOT as illustrated or described in ad. Additionally, the glass was quite thin. I noticed the weight seemed off when I received the shipment. I was immediately surprised at the weight, and when compared structure of with the grolsch bottles already in possession, it was visually clear how thin the glass is, and not suitable for carbonated drinks despite the description of the product. Also, as mentioned in other reviews, the locking mechanism is cheap and not suitable to keep carbon in the bottle.

Love these bottles! Love their size, the great packaging they arrived in, the ease to use the swing top, their classy classic appearance...just love everything about them. Easy to clean, fits perfectly in my mini fridge, simple yet sleek. My beautiful bubbly lemon yellow Jun kombucha shines in them. The thick syrupy brown molasses water kefir sizzles inside, calling to me to have 'one more'. They are aesthetically stunning! They are thick and solid, with no concerns about possible breakage. I've done 2nd ferments and not a drop seeps over the sealed top. No worries about accidental explosions either. I've tried other bottles that were patterned and was hugely disappointed in both their quality and swing top performance. Some arrived broken...which is not a good sign when it comes to 2nd ferments. I will clearly buy these again as my stock begins to fill up and I need more storage. These are well worth using as gift-worthy containers. A lovely simple red ribbon and bow tied around the neck would complete the elegant treat. Price was additionally reasonable and warranted. I will highly recommend these to my fermenting friends! Great product!

These are great for holding homemade kombucha, pre/probiotics, sodas, ect. They can take a lot of pressure!

I got this for my partner who makes her own Kombucha and this set of bottles works great for second fermentation. Sturdy, air tight, and it hasn’t exploded yet! So I’d say it’s great quality. Also a great size for gifting our friends/family with homemade Kombucha 😊 I only wish it were a bit cheaper since we don’t normally get the bottles back when we gift them haha

Solid bottle, but given its shape it does take some effort to clean and sterilize. You'll likely need a bottle cleaner and/or run it through the dish washer. Easy assembly and disassembly, great for fermenting and burping drinks, just make sure you keep an eye on it! I used it for a home brew of rice wine which develops its fizziness in the fridge. Bottle held up to the gas build-up, but definitely needed to burp the drink every other day.
