When you hear “unfiltered beer,” you probably think of a more natural drink, with a richer taste and a slightly cloudy appearance. In Romania, however, the term is often misused or confused, often erroneously referring strictly to unfiltered German white wheat beers (weissbier, hefeweizen, etc.). Moreover, many people believe that any beer that is less clear is “unfiltered,” without knowing exactly what the filtration process means and how it influences the quality and flavor. In fact, there is a clear difference between an unfiltered, unpasteurized, or craft beer – and understanding these nuances helps you choose better what to drink.

In the following lines, you will discover what unfiltered beer really is, why it tastes different from classic beer, what its benefits are, and why more and more beer lovers prefer it over industrial versions.

What is unfiltered craft beer?

When it comes to beer, the classic production process includes several stages: kneading the malt with water, boiling with hops, fermentation, maturation, and finally filtration . Filtration is the step by which the beer becomes clear and the remaining particles of yeast, proteins, and other residues are removed.

In the case of unfiltered craft beer , this step is omitted or minimally done. Thus, small natural particles of yeast and proteins remain suspended in the beer, which gives it a cloudy appearance, but also a richer and more complex taste.

The filtration process explained simply

Think of filtration as a fine “sieving” of beer. In industrial beers, special filters are used to almost completely remove yeast and sediment down to 0.45 microns, i.e. absolute filtration. The goal is to obtain a clear, crisp beer with a uniform/standard taste and a longer shelf life.

In unfiltered craft beer, this process is either reduced or omitted, to preserve:

• Brewer's yeast – rich in B vitamins and minerals.

• Natural flavors – more pronounced and closer to the original taste of fresh beer.

Why does unfiltered beer have a cloudier appearance?

The cloudiness comes from suspended yeast and proteins that haven't been completely removed. It's a sign that the beer is less processed. Most craft beers are unfiltered.

• Some consumers associate this aspect with something "unfinished", but in fact it is an indication that the beer is closer to its traditional, natural form.

• When serving, in the case of some beer styles (Hefeweizen, Weissbeer that have at least 50% wheat malt in the recipe) it is recommended to gently stir the bottle to homogenize the contents and enjoy all the flavor. However, in the case of beers with refermentation in the bottle (see Belgian beers, in particular) this is not recommended, on the contrary, it is contraindicated.

Differences from filtered beer

1. Texture:

• Unfiltered beer has a creamier and more "full" texture.

• Filtered beer is lighter and clearer.

2. Taste:

• Unfiltered retains more flavors – notes of yeast, malt, biscuits and a more complex taste.

• The filtrate is more “clear and standard”, but more “flat” in comparison.

3. Expiration date:

• Unfiltered, unpasteurized beer lasts less (usually a few weeks-months) because the live yeast continues to influence the product.

• Filtered beer has a longer shelf life (up to 2 years even), being stabilized through industrial processes.

Myths and confusions about unfiltered beer

Unfiltered beer has become a trend in recent years, being promoted as a more authentic and "natural" choice. However, there has also been a lot of confusion surrounding it. Let's clear up the most common myths.

Is it more "natural" or just differently processed?

Many people believe that unfiltered beer is 100% natural and that it does not undergo any processing. In reality, it is produced just like any other beer , using water, malt, hops and yeast. The difference is that it does not go through the intense final filtration that removes fine particles.

This means that:

• Unfiltered beer retains live yeast and proteins, which gives it a richer taste.

• It's not automatically "artisanal" or "organic" - large industrial factories also produce unfiltered but pasteurized beers, a process that stops the evolution of yeasts.

• It still remains a controlled process, just less aggressive on the beer .

So, yes, it's less processed than a filtered beer, but that doesn't mean it's completely devoid of technological intervention.

Does it contain more alcohol?

Another myth is that unfiltered beer is “stronger”. In reality, the alcohol content is not directly related to filtration , but to the recipe and fermentation process. In general, especially in the case of craft beers, the % alcohol is directly proportional to the degree Plato (EP), which also means the amount of malt in the primary beer wort. So the more malt, the higher the degree Plato (EP), which results in a higher alcohol content.

• An unfiltered beer can have the same alcohol percentage as a filtered beer of the same range.

• The only difference is that the yeast remaining in suspension can continue a light fermentation , but this does not significantly alter the alcoholic strength.

So you shouldn't expect a stronger effect just because it's unfiltered.

Is it healthier than regular beer?

Here things are more nuanced. Unfiltered, unpasteurized beer retains:

• B complex vitamins , minerals and antioxidants present in yeast.

• Nutrients in cereals , which are partially lost during filtration.

Theoretically, this gives it a slight nutritional advantage over filtered beer. However:

• The differences are not big enough to call it a "healthy drink."

• It still contains alcohol, so it should be consumed in moderation.

So, it may be a better choice for those who want a more natural beer , but it doesn't become a "nutritional supplement."

"I don't drink unfiltered beer, does it upset my stomach?" Truth or myth?

There is no direct link between unfiltered beer and such reactions, but studies show that there may be, as with other drinks, such as red wine, for example, a chemical reaction between beer and the food consumed or between the amount of food and beer consumed. :)

How to choose unfiltered beer by style

Unfiltered beer comes in a variety of styles, each with its own unique taste, aroma, and texture. Here are some of the most popular styles of unfiltered beer:

• Unfiltered IPA (India Pale Ale) :
  These beers are known for their strong hop aroma and a bitter, yet balanced taste with fruity or floral notes. Unfiltered IPAs tend to be more intense and complex due to the unfiltered yeast which preserves the natural hop flavors. If you like beers with a more “vibrant” and “intense” taste, this style is a great choice.

• Zăganu Hefeweizen unfiltered (wheat beer) :
  This is a light beer with a delicate taste and fruity notes, usually of banana or citrus. Due to the yeast left in suspension, unfiltered wheat beer has a creamier texture and a smoother effervescence. It is a milder style, ideal for those who are new to the world of unfiltered beer.

• Zăganu Pilsner Lager unfiltered :
  Unfiltered lager retains the same characteristics as a classic lager – it is a refreshing, easy-drinking beer, but with a fuller taste and more complex aroma due to the unfiltered yeast. It is a good choice for those who prefer lighter beers but want to try something with more personality than a standard filtered lager.

• Zăganu American Pale Ale Unfiltered: Similar to IPA, but with less hop and bitter intensity. Unfiltered Pale Ale has a more balanced taste, but retains a richer character, with notes of malt and fruit. It is a good choice for those looking for a flavorful beer, but not very intense.

Tips for choosing :

• If you prefer intense, aromatic hop flavors, try Zăganu IPA or Pale Ale, both of which are unfiltered and unpasteurized. If you want a very “hazy” and super-aromatic experience, then Zaganu New England IPA is what you’re looking for.

• If you prefer light beers but with a more complex taste, a Hefeweizen or an unfiltered Pilsner are excellent options.

• For those who are new to exploring unfiltered beer, start with a Hefeweizen, due to its milder and easier-to-understand taste.

For those who are new to exploring unfiltered beer, a Zăganu Hefeweizen may be the perfect choice. With a delicate, slightly fruity taste and a velvety texture, this wheat beer is an ideal option for a first encounter with unfiltered beer. Try Zăganu Hefeweizen now!

The benefits of unfiltered beer

Unfiltered craft beer is chosen by many not only for its image as a "more natural product", but also for the different experience it offers. Here are the main benefits that make it special.

Richer and more authentic taste

Filtration removes fine particles of yeast and proteins, but also some of the flavors that give complexity to the beer.

• Unfiltered beer retains a more intense flavor , with slightly smoother notes and closer to beer freshly removed from the fermenter.

• The texture is fuller, sometimes slightly creamy, and the flavors can vary slightly from one batch to another, making it more interesting for connoisseurs.

For those used to perfectly clear commercial beers, this taste may seem more aromatic, but that's exactly what gives it authenticity.

Preserved nutrients – yeast and B vitamins

Because it is not completely filtered, beer retains live brewer's yeast and some of the proteins and nutrients that are lost in filtration. These contain:

• B complex vitamins , essential for metabolism and skin health.

• Minerals such as magnesium and potassium , in small but present quantities.

• Natural antioxidants from grains and hops.

Obviously, beer remains an alcoholic beverage and cannot be considered a "healthy" food in the strict sense, especially in the case of irresponsible consumption, but compared to a filtered beer, it has a slightly richer nutritional profile .

Fewer industrial processes

Unfiltered is not subjected to that intense filtration that "uniformizes" the taste and appearance.

• It is closer to the traditional beer production process , being less "standardized".

• This makes it a favorite for those looking for craft beers with minimal processing intervention .

However, it should be noted that some unfiltered beers are also produced on an industrial scale and pasteurized, so they are not automatically artisanal or organic.

The experience of a product closer to traditional beer

• Before modern technology allowed for advanced filtration, all beers were unfiltered . Drinking an unfiltered beer gives you an experience closer to what was drunk hundreds of years ago in breweries.

• It is an option for those who want to experience beer in its more "lively" form, with slight taste variations from one production to another.

• In a way, unfiltered is a bridge between modern industrial beer and the tradition of old brewers.

Disadvantages of unfiltered beer

Although it has many advantages, unfiltered beer also comes with a few peculiarities that may be considered disadvantages for some consumers.

Shorter shelf life

Because it keeps the yeast alive and is not completely stabilized by filtration, unfiltered:

• It has a shorter shelf life than filtered beer.

• It must be consumed relatively quickly after production, otherwise the taste may change.

• It usually requires storage at lower temperatures, sometimes even in the refrigerator, we at Zăganu recommend below 10C and away from sources of heat or natural light.

This makes it more difficult to transport and store long-term.

Cloudy appearance, which can confuse and change taste perception.

Some consumers, accustomed to perfectly clear beers, believe that cloudiness means the beer is "spoiled."

• In fact, the slightly opalescent or sedimentary appearance is normal and comes from yeast and proteins.

• However, it can be a visual shock to those who associate clarity with "quality."

If you are looking for a more intense taste, Zăganu X Guerrilla Pale Lager Anniversary Edition can be an interesting choice. This beer brings a perfect balance between a slightly bitter taste and a more pleasant texture, offering a more complex beer experience and closer to modern traditions.

More intense taste, not to everyone's liking

Unfiltered has a richer taste, but that can also mean more intense hop notes (in the case of IPA-style beers or stronger ones).

• Those who prefer a "light", neutral and very easy-drinking beer may not be pleased.

• For a consumer accustomed only to industrially filtered lager, the taste may seem "too much" and harder to drink "more than one".

How do you choose a quality unfiltered beer?

If you want to truly enjoy the experience of unfiltered beer, here are some useful tips:

Check freshness

The shelf life matters a lot for unfiltered.

• Choose the freshest options possible, preferably recently produced.

• If the bottle has deposits, pour half the beer into the glass, then gently shake the beer before filling the glass – but only if the manufacturer recommends this or if the beers are unfiltered wheat (Hefeweizen).

Read the label

Some beers are "semi-filtered" and just go by the name of unfiltered.

• Look to see if it clearly states "unpasteurized" or "naturally fermented."

• Check the ingredients – a short list (water, malt, hops, yeast), of natural ingredients that can be easily pronounced is a good sign.

Start with gentler styles

If you're not used to strong flavors, try this at first:

• An unfiltered lager, closer to what you already know.

• Hefeweizen (unfiltered wheat beer) , which has fruitier and friendlier notes.

• Only then can you move on to more complex styles, such as unfiltered IPAs or other craft beers. Be sure to try Zăganu New England IPA, a complex beer with strong fruity hop aromas, very "hazy".

When you want a quality beer, always choose fresh and well-preserved variants. Try a Zăganu Hefeweizen for an authentic wheat beer taste or a Zăganu Double Rye IPA for a more intense and aromatic experience. Both options are excellent for those who want to discover a beer with a special character and flavor. Choose Zăganu IPA and Zăganu India Pale Lager for a complete tasting!

Frequently asked questions about unfiltered beer

Does unfiltered beer contain gluten?

Yes, unfiltered beer, like most beers, contains gluten because it is produced from malted grains, mainly barley, but also wheat. People with gluten intolerance should avoid unfiltered beer unless it is specifically labeled as gluten-free.

Can I drink unfiltered beer if I'm vegetarian or vegan?

Unfiltered beer is usually considered suitable for vegetarians, Zăganu is certified VEGAN, as it contains no animal ingredients. However, some breweries use fining agents from animal products (such as gelatin), and this may affect the choice of those following a vegan diet. It is best to check the label or ask the manufacturer for further details.

What is the difference between unfiltered beer and unpasteurized beer?

Unfiltered beer does not go through the final filtration process, leaving yeast particles and proteins in suspension, which gives it a cloudy appearance. On the other hand, unpasteurized beer is beer that has not undergone pasteurization to stabilize it, thus preserving the yeasts alive. While these beers may be similar in style, the pasteurization process is unrelated to filtration.

Can unfiltered beer be stored at room temperature ?

In general, unfiltered beer should be stored in the refrigerator or a cool place to maintain its freshness. Since it contains active yeast, it can continue to ferment, which can affect the taste and shorten its shelf life. It is recommended to consume it as soon as possible after purchase and keep it refrigerated throughout, as the low temperature slows down the fermentation, aging and oxidation processes.

Is unfiltered beer more expensive than filtered beer?

Yes, unfiltered beer can typically be more expensive than filtered beer. This is due to the lower volume and more specialized production process of unfiltered beer, as well as the specific marketing for craft beer. Additionally, due to the shorter shelf life, some unfiltered beers may also incur higher distribution costs.

Can unfiltered beer be a risk to my health?

In general, unfiltered beer is safe to drink, but it is important to store it properly to prevent the growth of harmful microorganisms. If beer has been stored at inappropriate temperatures or is expired, there is a risk that it will ferment, which could affect its quality and taste, as well as its safety. Drinking beer in moderation is always recommended.

What types of unfiltered beer are available on the market?

There are many types of unfiltered craft beer available on the market, including classic lager, ale, IPA, and wheat beer styles. Many craft breweries are also producing unfiltered beers in innovative styles, with unique flavors and ingredients that add variety and complexity to the taste. Looking for the words “unfiltered” or “natural” on the label is a good way to find these options.
