      Things to Consider When Buying Flasks

      When setting out to buy a quality hip flask, there are a few details that should remain in the back of your mind. Unfortunately, not all flasks are made the same, and some offer a lower grade quality. Taking into consideration things such as materials, capacity, and design is essential. Keep these pointers in mind, and you can’t go wrong.

      1. Capacity

      Capacity plays a crucial role in helping you decide whether a flask is for you. If you prefer a smaller flask, great, but keep in mind the amount of fluid you want to be able to carry with you.

      Most flasks range from between four-ounces to eight-ounces. The general rule of thumb is that one shot is approximately 1.5-ounces. A six-ounce flask leaves you with about four shots.

      Figure out on average how many drinks you want to have and how many shots that work out to be. The result here should give you a good indication about what size flask to buy. Another thing to keep in mind is where you intend on keeping your flask. Overly large ones may not fit as neatly in your pockets.

      2. Materials

      The materials used to make your flask are very important. Manufacturers use a variety of metals, yet very few will last.

      Pewter sees a blend of metals that includes lead, resulting in its being banned for drinking and eating utensils. It is also known to alter the taste of your beverage negatively. With this in mind, the best pewter flask is the one that stays in the display cabinet.

      A titanium flask offers unique strength and durability. This makes them perfect for outdoor use. They are less likely to become dented or scratched, but they are more costly.

      This leaves us with what is widely considered the best flask material: stainless steel. This alloy metal is resistant to rust and corrosion, making it perfect for a vessel made to carry liquid. Because it won’t rust, stainless steel is ideal for engraving. The best hip flask is one that has your personal details.

      3. Design

      Keep in mind the design of the flask when purchasing one. How does it feel? Is it shaped in a way that sits comfortably in your pocket? And how is it put together? A well-designed flask won’t cause you discomfort, and it won’t leak.


      1. What are flasks used for?

      The hip flask is generally used to carry premium liquor to an outing or event. It allows you to take your favorite beverage with you wherever you go. While flasks are now quite acceptable, they haven’t always been that way.

      During the Prohibition era, the flask gained popularity as a solution to keeping and carrying liquor. They referred to men who had a hip flask in their pockets as “Hipsters.” Individuals who kept them in their boots were known as “bootleggers.” These flasks needed to remain concealed, and their shape and design made this easy.

      Since then, the humble hip flask has become an everyday accessory amongst gentlemen. A useful vessel that allows you to carry your most-loved beverage with you whether you go camping or to a black-tie event.

      2. What can I carry in my hip flask?

      You could assume that being made from metal, hip flasks can hold just about any liquid. Unfortunately, you would be wrong. It is the metal itself that prevents a selection of beverages from being stored in a flask. The properties of the metal react with specific liquids, leaving your beverage tasting metallic. Other fluids will cause your flask to corrode.

      Beverages you don’t want to keep in your flask include:

      • Creamy liqueurs
      • Carbonated sodas and mixers
      • Beers, or other fizzy alcopops
      • Citrus-based beverages
      • Wines or champagne

      Flasks are designed to hold hard liquor only. Hard liquor is generally considered as being those spirits with a proof of 80% or more. These include:

      • Whiskey
      • Gin
      • Brandy
      • Tequila
      • Rum
      • Bourbon

      The precise nature of these flasks lends them a certain air of exclusivity. A notion that seems to please many.

      3. What is flask etiquette?

      Flask etiquette covers the basic, unspoken rules that surround flasks and their use. Like anything in society, there are do’s and don’ts for using these accessories. Whether or not yours is the best whiskey flask around, not practicing common courtesy will leave you unpopular.

      For example, taking your flask to an establishment that already sells liquor is rude.

      It is also considered poor form to take your flask into spaces that you wouldn’t usually bring alcohol to. Funerals, places of worship, and airplanes are a few of these scenarios.

      Be aware of the rules in your state that concern carrying open vessels of alcohol. Getting caught with your liquor open could lead to a fine.


      We hope we shared some insightful and intriguing facts with you about the best flasks for whiskey or another hardtack. If you are in the market for a flask of your own, then be sure to look at our reviews a little closer.

      If you are looking for a fast-tracked answer about which flask we think is the best, then you can’t go wrong with Gennissy’s stainless steel flask. It ticks all the boxes, from a sleek design to handy accessories. With this flask, you can’t go wrong.
