Glass vs Stainless Steel French Press: Weighing The Pros and Cons

The French press may appear to be a simple tool for brewing, but the rich coffee it produces makes it a really popular method of making a cup of joe.

However, starting out can be quite the quest when you’re finding the right French press. I’ve been there, trust me. I found that the material used for the French press is an important factor for different reasons.

In this article, I’ll go compare glass and stainless steel French presses (the two best options for coffee lovers), so you can make a wise choice when purchasing one.

What is a French press?

A French press, also known as a cafetière or coffee plunger, is a cylindrical coffee maker that is used to steep coffee grounds in hot water for a few minutes before you push down the plunger to filter out the ground coffee.

The resulting drink is a rich and full-bodied cup of French press coffee.

Since there are concerns about French press and how sediments could get into your coffee with this method, here is my favorite French press coffee recipe to minimize sediments.

When it comes to French press materials, there are different choices available on the market:

  • Glass
  • Metal (stainless steel)
  • Plastic
  • Ceramic

Among these options, glass and stainless steel are the most popular and common picks of coffee lovers. Let’s have a closer look at the main differences between the two to help you decide which one suits you better.

Glass vs Metal French Press

Glass and stainless steel each have their own advantages and disadvantages. Check out this overview of their pros and cons below:

MaterialProsCons
Stainless steel– More durable and shatter-proof
– Highly portable
– Better heat retention
– Opaque so you can’t see the brewing process
– Generally more expensive
Glass– Classic aesthetic
– Generally lower price point
– Transparency allows you to see the brewing process
– Can shatter
– Not as portable as steel material

There’s no exact answer as to which one is better between glass and metal French presses. It really depends on your needs. My take on the question though:

  • Stainless steel is perfect if you prioritize durability and portability.
  • On the other hand, if you like the timeless and classic style that allows you to look through your brew at a more affordable price, go for a glass French press.

Comparing Glass and Stainless Steel French Presses

Now let’s have a closer look at each of the features that these French presses have to offer. Here’s an overview:

FeatureGlassStainless steel
Durability– Can shatter
– Borosilicate glass is thermal shock-resistant
– Most durable option
Portability– Lighter but fragile– Heavier but very durable and better for travel
Taste– Extracts flavor with no issues– Some lower-end models can add a metal taste
Heat Retention– Loses heat faster– Can retain heat for 1-2 hours
Style– Classic and stylish aesthetic
– Transparency allows you to see the brewing process
– Modern look
– Opaque material
Cleaning– Mostly dishwasher safe
– Metal mesh needs extra care
– Bit more straightforward to clean
Price Point– More affordable than the stainless steel French press– More expensive than the glass French press

Durability

Glass French presses are more delicate compared to their stainless steel counterparts. They can break if dropped or knocked over during cleaning. I’ve also heard of them shattering due to thermal shock on occasion, but that is rare. (Still a point to make sure to always preheat the glass.)

On the other hand, stainless steel is sturdier and less likely to break even when accidentally bumped off the counter or while cleaning. And it will never explode due to thermal shock.

It is important to note though that glass French presses are often made with borosilicate glass, which is thermal shock-resistant and sturdier than standard glass.

Portability

When I travel, I like bringing my trusty brewing equipment with me. If you also prefer brewing your coffee wherever you go, then portability should also be a priority. The obvious choice here is the stainless steel French press since it’s not prone to breakage like a glass French press.

It’s worth noting though that glass variants are generally lighter than stainless steel ones.

Taste

Another thing worth considering when picking between the two materials is their effects on taste. Glass French press can extract great flavor for your cup without any issues. There is no residual taste, since glass is non-pourous. If you clean it properly, it will brew perfectly clean cups of coffee.

For low-quality metal French presses, however, there are some cases where there’s a slight metal taste added to the coffee. This is why I recommend purchasing from reputable brands such as Espro, Bodum, and Frieling if you prefer stainless steel. And don’t forget to give it a thorough cleaning after every use especially if you’re using oily coffee beans.

Heat Retention

The ability of a French press to retain heat is essential as it affects the brewing process and coffee’s taste. A glass carafe tends to lose heat faster compared to stainless steel. To give the glass slightly better heat retention, you can (and should) preheat your French press before brewing.

With its insulating capability, the stainless-steel carafe allows you to brew your coffee with boiling water and still enjoy hot coffee even after an hour or two in theory. But of course, you wouldn’t really do that, as that would over-extract your coffee and cause it to become bitter

You can even get double waller metal French press, which has even better heat retention.

Whichever material you use though, it is still best to consume your coffee as soon as possible after brewing.

Style

There’s no denying that glass French presses look beautiful on any kitchen countertop with their sleek and elegant design. The ability to see the coffee brewing process adds an extra appeal that many coffee enthusiasts find attractive.

However, stainless steel options often come in various unique designs, from classic models to modern ones, adding personality and style to your morning routine as well.

Cleaning Up

Cleaning up after using your French press should be easy and hassle-free, but it does take a few minutes. The process is the same for both the metal and glass variants.

Price

When it comes to cost, glass French presses tend to be more affordable than their metal counterparts. If you’re looking for an affordable option without compromising quality, then a glass French press may be perfect for you.

In contrast, stainless steel versions are often pricier due to the higher manufacturing costs of this sturdy material. The difference between price is about 20-30%.

Picking the Right French Press Size

Aside from the material used, it is also important that you pick the size that suits you best. French presses often come in four sizes which can cater to your different needs. Here’s a comparison of the French press sizes:

ModelCapacityServings
3-Cup0.35 l / 12 oz1 serving
4-Cup0.5 l / 17 oz2-3 servings
8-Cup1 l / 34 oz4 servings
12-Cup1.5 l / 511 oz8 servings

Conclusion

Both glass and stainless steel French Press coffee makers provide excellent quality coffee; selecting between the two really depends on personal preference. If you prefer a slightly more affordable option that looks great on your countertop, then glass might suit you best. But if you don’t mind paying extra bucks for durability, portability, and heat retention, then investing in a high-quality stainless steel model would be better for you.

At the end of the day though, we all want to sip on a great cup of coffee, and there’s a good reason why the French press is one of the most popular brewing methods. After you’ve mastered using the French press, go ahead and try different recipes such as a French press cold brew, Cafe au lait, and more.
