What to Look For in a Flask


The most important question to consider is how will you use it? Is this going to be slipped into a bag, purse, or pocket for sipping on the sly? Will you take it with you for walking and adventuring in the outdoors? Your intended use is a strong determining factor for what type of flask to purchase.


Similar to use, the material is important. You might prefer something lightweight; typically, stainless steel isn’t a very heavy material for flasks, and it’s easy to clean. Maybe you need a material that’s more durable or that’s got some reinforcements around the edges with silicone. Perhaps you’re looking to gift a flask and like the looks of those wrapped in leather or other materials. Some flasks will benefit from polishing, too, to keep them shiny; that’s another consideration. How much do you want to have to fuss with your flask?


Flasks can vary quite a bit in their capacity for liquid. Many hover around 6 ounces, but others can hold up to 8, 10, or even 11 ounces. Some are oversized and designed that way (such as those that can hold up an entire bottle of wine), which makes them great for taking on the go and sharing with others.

What should a flask be made from?

Most flasks (although not all) are made from high-grade stainless steel that resists rusting and can be cleaned easily. The exterior can be polished but doesn’t scratch easily, and stainless steel doesn’t typically impart any taste to whatever contents you put in the flask.

How do you clean a flask?

The easy answer is soap and water. But if your flask has started to take on a smell, a bottle brush will help get into the corners for a deeper clean. Boiling water will help break down lingering scents, or if you’re looking for something more heavy-duty, add white vinegar or lemon juice and water to the flask, close it up, and give it a good shake. Rinse several times in hot water to remove that acidic smell.

How many ounces/liquid does a flask hold?

Flasks are available in a range of sizes, though the standard flask holds 8 ounces. Larger flasks are available if you’re carrying drinks for two.

What alcohol is best for a flask?

The best thing to sip from a flask is hard liquor, be it scotch, rum, bourbon, brandy, or gin. Anything below 40% ABV—that means beer, wine, and cocktails—will not keep well in a flask.
