Things to Consider Before Buying a Flask

Most flasks look alike, but there are areas that differentiate them from each other. If you know what to look for, then you’ll end up buying the best flask for yourself and others. 

  • Size

There are different sizes of flasks. A flask can hold from 150 ml of alcohol to 360 ml. The standard size of a flask can hold 236 ml, which is about 8 ounces. Choose the most convenient size for you. If you’re trying to control your alcohol consumption, go for a smaller flask. A small flask is also more convenient.

  • Materials

A flask can be made with either aluminum, stainless steel, titanium, pewter, plastic, glass, silver, and copper. The cheapest kind of flasks is made with plastic while the most expensive ones are made with silver. The best flasks have the quality and durability that depend on the material used, so knowing what material a flask is made with is a must. Among these materials, stainless steel is the best option for the following reasons: it is the most durable, it is very affordable, it’s easy to find, and it won’t develop any unwanted flavors.

  • Shape

A flask can be of any shape, but the most common one is rectangular. Some are designed aesthetically. Novelty items offer round-shaped flasks. If you want a flask that is comfortable to carry and doesn’t attract any attention, go for a curved flask or also known as a hip flask. The curve makes the flask attach to your body naturally, which keeps it hidden.

  • Design

Sometimes, a flask can be plain-looking. That’s why some brands tend to add something to the surface to elevate the overall look. You can often see laser engravings or prints. Others have a glittery and sleek body to make them look pleasing. There is also faux leather wrapped around the flask’s body for extra protection, making it non-slip. 

  • Price 

Flasks usually go around $10 - $30, so it’s generally not a very drastic price point. But, there are also offers that include about five flasks in one set for a lower price. In a way, you can save money and at the same time have extra ones for friends. 

  • Other features

Some flasks come with a funnel, and this is something you should look for when buying one as it can be handy, especially when you have to pour the alcohol into a small opening. The funnel helps you avoid spills and mess. Some of the best flasks also include a shot glass or pourer spouts for a better drinking experience.

  • Cap

It’s more convenient and smarter if you choose a flask with a hinged cap. It adds to the flask’s aesthetics, and you don’t have to worry about losing it. Screw-down caps also provide a tighter seal compared to other cap types. They also present leaks so you won’t waste your liquor.

Best Flask FAQ

1. Is it safe to store alcohol in a flask?

In general, there are no severe health hazards when drinking alcohol from a flask, even after being stored there for a long time. The only downside you’ll be facing is the metallic taste it has acquired, but it doesn’t necessarily harm you.

2. What can you put inside a flask besides alcohol?

You can store any liquid inside a flask, whether it’s juice, water, lemonade, or water. You can even put soup inside. Just make sure you can enjoy whatever you put inside at room temperature. To add to its versatility, you may even use a flask to store rubbing alcohol when you’re out camping. However, carbonated or acidic drinks quickly pick up metallic flavors.

3. What alcohol can you store in your flask?

Experts suggest that any hard liquor with 80 proof and beyond is okay to be stored in a flask. Examples include rum, whiskey, brandy, gin, and bourbon. 

Any cream liqueurs, citrus-based alcohol, wine, beer, or low-alcohol drinks are discouraged from being stored in a flask because low-alcohol drinks can quickly deteriorate and mix with the flask material. Moreover, flavored alcohol isn’t good inside a flask as well.

4. What are the flask etiquettes?

There is a set of flask etiquettes that need to be followed if you own one. These are the following:

  • If you’re going to get aboard on a plane, do not bring any flask with stored alcohol. That is not allowed inside.
  • Bring a flask with your favorite spirit inside if it won’t be available at the party.
  • Don’t bring a flask if you want to get drunk.
  • Share a drink from your flask with some friends. 
  • Carrying a flask occasionally is a yes, but having one every day is a no.
  • Don’t drink and drive.

5. How long can you store alcohol in a flask?

It is best if you store the amount of alcohol you can finish in a day. One week is the furthest the alcohol can go inside a flask. There are also cases where the alcohol can develop a metallic taste after being stored for more than three days. However, there is a way to slow down this metallic taste acquisition: you should put your flask somewhere cool and dark.

Conclusion

Wherever you may be, a trusty flask will provide you with your favorite liquor, either to enjoy or to simply get through the day. Alcohol companies always remind drinkers to drink responsibly, and a flask is one way to do so because the liquor is consumed in small amounts at a time.

The Stanley Classic Flask is an excellent way to start because it is long-lasting, and you can bring it anywhere. But, if you’re feeling generous, the P Lab Customized Flask makes a fantastic gift to your loved ones because it is made explicitly for them. 

We hope you enjoyed our list of the best flasks. Which flask do you have your eyes on? Let us know in the comments.
