We use glass flask bottles to infuse liquors and to store and make homemade salad dressing. Since both of those tasks involve shaking the flasks to mix ingredients, we recommend a bottle with a top that stays sealed and sturdy glass.

What to Look For in Glass Flasks
If you’re going to be doing infusing, you may think any of them will do. There are just a few things to look for:
- Does it seal well enough that you could shake it without it leaking or coming open? Most of our infusions call for shaking, and salad dressings need it frequently. The best seal gives you the best infusion and storage time.
- What’s the right size for your project?
- How easy are they to clean?
After that, the only real consideration is style. Pick what you like the look of, as long as it’s quality.
Glass Bottles for Infusions
Bormioli Rocco Fiaschetta Glass Flasks, set of 4
- Sealing: excellent based on my experience
- Size: 8.5 ounce (250ml)
- Ease of cleaning: Dishwasher safe. Handwashing easy with bottle brush.
These 8.5 ounce (250ml) are the flasks we've used for all our infusions on this site. Pictured here is our Jolly Rancher Vodka Infusion. We infused it in these bottles and also served it in them.
They have a cork top with a rubber hermetic seal that expands to keep the liquid in and the air out. Despite how tightly they close, opening them is easy with the metal swing top.
You can also use these for making and storing homemade salad dressing, fermenting kafir and kombucha, homebrewing and more. They're about the same size as the smaller traditional store bought dressings.
You can put labels on the front (we're partial to these erasable erasable chalkboard labels labels). This is great for knowing exactly what's in each bottle, and you can also date them so you'll know when they've reached the end of their shelf life.
Dishwasher safe but also easy to clean by hand. They also have no problem being put into the freezer to chill an infusion.
The Vintage Personalized Glass Flask
- Sealing: great, based on reviews. It's a cork, which can be replaced
- Size: 6.7 ounce (200ml)
- Ease of cleaning: bottle is dishwasher safe
This engraved, personalized flask makes such a fantastic gift, or something you want to own for yourself. The quality is high.
The seal is a simple cork, which performs well and can be replaced with another cork of the same size if it breaks down over time.
16oz Round Swing Top Bottles, Set of 6
- Sealing: excellent, based on Amazon reviews
- Size: 16 Ounces (473ml)
- Ease of cleaning: Dishwasher safe. Handwashing easy with bottle brush.
These beautiful 16 ounce bottles are reminiscent of old fashioned soda bottles. This set of six is great for fermentation, and come with three extra stoppers and a collapsible silicon funnel.
The stainless steel closures won't rust in the dishwasher and the tops close so well that you might occasionally find them a little hard to open.
But that's a good thing, especially when you're fermenting. And one of the most popular uses for these bottles is brewing kombucha.
These are also great for storing home brewed beer.
Nakpunar 6 pcs Glass Flask Bottles with Black Tamper Evident Cap - 200 ml
- Sealing: excellent, based on Amazon reviews
- Size: 7 Ounces (200ml)
- Ease of cleaning: Dishwasher safe. Handwashing easy with bottle brush.
These Nakpunar flasks are perfect if you want to buy in bulk and give your infusions away. I've linked here to the 6 flask set, but there's also a very affordable 12 flask set.
These bottles are simple with a black screw on cap. Reviewers report shaking their infusions vigorously in these bottles without any sign of a leak. They're a slightly smaller size than the rest of the flasks on this page.
They also have a flat front - like the Bormioli Roccos - that's great for applying a printed label. Perfect for gifting homemade liquor invusions to friends and loved ones.
Bormioli Rocco Giara Swing Top Bottles 33 ¾ Ounce-4 Pack
- Sealing: excellent, based on Amazon reviews

- Ease of cleaning: Dishwasher safe and easy to hand wash with a bottle brush.
These tall, elegant 1 liter bottles are perfect for infusing infusing a whole bottle of vodka or rum. It's also great for making agua fresca, or infused water.
These come highly recommended by friends who have used them for fermenting kefir or kombucha, or for home brewing beer and ginger beer. And also for storing their own homemade spirits or infused water, iced tea or lemonade in the refrigerator.
They're also great for storing household cleaners and laundry products when you don't have the room for the big bulky containers they come in.
They're the same brand as our top recommended bottles, Bormioli Rocco.

This Nevlers set of 17 ounce (500ml) bottles come with everything you need for infusions. A funnel for adding ingredients into the bottle, a bottle brush for cleaning, and a gold marker for labeling each bottle.
These are great for infusions, and also for making and storing simple syrups and homemade spirits. You can also store oil and vinegar in them.
