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

Awesome product for kombucha.

Superb for my craft gins .

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.

Good size and well made

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!!

Excellent for kombucha second ferment. Withstand quite a lot of pressure and they look so cute. Happy indeed.

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!

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

My husband makes his own batches of kombucha & LOVES these for them!!!! They’re air tight, food grade, HEAVY, & very high quality.

I bought a second set. They don't explode and make great fermenting bottles. Good quality stoppers and rubber rings.

Very sturdy bottles, still without issues.
