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. These are the ones that have worked for us.
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 chalkboard 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.
These require hand-washing, but are very easy to clean. They also have no problem being put into the freezer to chill an infusion.
These beautiful 34 ounce (1000ml) bottles are reminiscent of old fashioned soda bottles. This set of six are specially designed for fermentation, and come with three extra stoppers and a collapsible silicon funnel.
They are BPA and lead free. 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.
They are dishwasher safe, but some users prefer to clean them by hand and report they are very easy to clean either way.
These are also great for storing home brewed beer. They are dishwasher safe.
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. They are dishwasher safe.
This mockins 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.
These glasses are also great for storing beverages in the refrigerator. Use them for iced tea, fruit juice, milk, or infused water.
These are dishwasher safe, but it is not recommended to put them in the freezer.
