What is Unfiltered Beer – Discover The Unconventional Full Bodied, Malty Beer Style

Introduction to Unfiltered Beer

The beer world is vast and diverse, boasting a myriad of styles, brewing techniques, and flavors. One such style that has caught the attention of beer aficionados and casual drinkers alike is the unfiltered beer. Picture this: you’re cracking open a bottle of your favorite brew.



As you pour it into your glass, you notice a distinct haziness, almost as if the beer is cloaked in a soft veil. Along with this visual peculiarity, the flavors seem to dance more intensely on your palate, presenting a symphony of taste that leaves a lasting impression.



This is the allure of unfiltered beer. But let’s deep dive into what gives unfiltered beer its unique character, and why is it considered different.

Understanding Beer Filtration

To fully appreciate the concept of unfiltered beer, we must first lay some groundwork by explaining the process and purpose of beer filtration.

Purpose of Filtration in Beer

At its core, the filtration process in beer making serves three major purposes. Firstly, it’s done to clarify the beer. Clarity is often equated with quality in the minds of many beer consumers, making it a desired attribute.



Secondly, filtration aids in enhancing the beer’s stability. This means preventing the development of off-flavors or unexpected changes in the brew over time. Lastly, it ensures consistency. Brewers want their beer to offer the same taste, appearance, and quality across different batches, and filtration aids in achieving this uniformity.

The Filtration Process

The filtration process itself involves passing beer through various filtration materials—such as diatomaceous earth, perlite, or membranes—which act as a sieve, trapping particulates, including yeast cells and grain particles, and removing them from the final product. But what happens when brewers decide to eschew this commonly followed process?

What is Unfiltered Beer?

When we talk about unfiltered beer, we’re referring to beers that skip this filtration step, leading to some interesting effects. In simple terms, unfiltered beer is a type of beer that retains certain components—namely, yeast and grain particles—that are usually filtered out in the beer-making process. By allowing these components to remain, brewers create a beer that offers a different drinking experience.

How Unfiltered Beer is Made

The production of unfiltered beer mostly mirrors the conventional brewing process, with one significant exception: the beer is not subjected to filtration after fermentation. This omission allows the yeast, along with other substances, to stay within the beer, resulting in a brew that carries a more robust flavor profile, a distinctive appearance, and a character quite unlike its filtered counterparts.

Taste of Unfiltered Beer

One of the most exciting aspects of unfiltered beer is the distinct and rich flavor it imparts, owing to the presence of yeast and other residual components.

Flavor Profile

Unfiltered beer often offers a more robust and intricate flavor experience. The yeast and other suspended particles in the brew contribute an additional layer of depth and richness to the beer’s flavor. This can manifest as an enhanced taste of the grain, a more noticeable fruity or spicy character, or a stronger expression of the beer’s inherent flavors.

Comparison to Filtered Beer

When compared to their filtered counterparts, unfiltered beers might present a more ‘raw’ or ‘authentic’ profile. They retain a stronger connection to the original ingredients used in the brewing process. Many beer enthusiasts describe the taste of unfiltered beer as being closer to ‘real’ or ‘traditional’ beer.

Visual Difference Between Filtered and Unfiltered Beer

Beyond flavor, the absence of filtration also imparts a visual difference to the beer.


Unfiltered beers tend to exhibit a cloudy or hazy appearance resulting from the presence of yeast and other particulates. This cloudiness is one of the defining characteristics of unfiltered beer, setting it apart from the crystal-clear look we often associate with commercial beers.


Furthermore, sediment—comprising spent yeast and other remnants from the brewing process—may settle at the bottom of the bottle or glass of an unfiltered beer. This sediment is completely normal and safe, though it may be a new sight to those accustomed to filtered beers.

Health Aspects of Unfiltered Beer

The health implications of unfiltered beer are a fascinating, albeit complex, topic. From potentially beneficial aspects to certain considerations, here’s what you need to know.

Nutritional Content

Unfiltered beer retains more of the vitamins and proteins inherent in yeast, which are typically removed during filtration. This means that, in comparison to filtered beer, unfiltered beer might be more nutritious, offering a greater range of B-vitamins and amino acids.

Potential Health Benefits

The yeast in unfiltered beer can also play a beneficial role in gut health. Acting as a probiotic, it can help maintain a healthy balance of gut flora. However, it’s essential to remember that these benefits don’t grant unfiltered beer a “health food” status—it’s still an alcoholic beverage and should be consumed in moderation.

Health Concerns

On the downside, unfiltered beer might contain higher levels of allergens, such as gluten and other substances, that could potentially trigger negative reactions in people with sensitivities or allergies. This is something to keep in mind if you’re contemplating trying unfiltered beer and have known food or beverage sensitivities.

Popular Types of Unfiltered Beer

Unfiltered beers span a range of styles, each offering a unique tasting experience. Here are a few popular types to get you started on your unfiltered beer journey.

Wheat Beer

Wheat beers, which often encompass styles like Weissbier and Witbier, are frequently served unfiltered. The cloudiness conferred by the yeast accentuates their naturally fruity and spicy flavors, making for a refreshing and complex drink.

Saison, a traditional Belgian style, is known for its unique, funky character—a result of specific yeast strains and, often, a lack of filtration. An unfiltered Saison further enhances this distinctive profile, delivering an authentic Belgian beer experience.


While not all IPAs are unfiltered, a significant number of brewers choose to leave their IPAs unfiltered to emphasize their robust hoppy characteristics. Unfiltered IPAs often exhibit a hazy appearance and a more complex flavor profile, with hop bitterness beautifully complemented by a full-bodied texture.


Although it’s less common to encounter unfiltered lagers, they do exist. Unfiltered lagers retain a fuller body and exhibit richer flavors compared to their filtered versions, making them an exciting option for lager enthusiasts seeking something different.

Best Practices to Enjoy Unfiltered Beer

If you’re ready to explore the world of unfiltered beers, there are certain best practices to enhance your experience. The best idea to taste multiple beers is always a beer flight where you can taste a few different beers of one style of a few different beer types, but you should always pay attention to a few key details. 

Serving Temperature

Unfiltered beers are often best enjoyed slightly warmer than typical fridge temperature. This allows the beer’s complex flavors to shine and ensures you get the most out of your unfiltered brew. The ideal temperature may vary depending on the specific beer style, so it’s always a good idea to check for any serving suggestions on the bottle.

Pouring Technique

When pouring an unfiltered beer, you should pour slowly and deliberately to avoid disturbing the sediment that might have settled at the bottom. The goal is to leave this sediment in the bottle—unless you’re drinking a traditional German Hefeweizen or another beer style where the sediment is typically mixed into the beer.


It’s best to store unfiltered beers upright, which allows the sediment to settle at the bottom of the bottle. This way, it will be easier to pour the beer without disturbing the sediment.


In conclusion, unfiltered beer offers a captivating alternative for beer lovers looking to deepen their exploration of diverse beer styles. With its distinct flavors and unique appearance, this type of beer provides an experience that’s closer to the heart of the brewing process. 

The suspended yeast and particulates not only contribute to the beer’s character but also serve as a reminder of the raw, authentic ingredients that go into each bottle. Whether you’re a seasoned beer connoisseur or a casual drinker, unfiltered beer is a route worth traveling on your beer discovery journey.
