An Honest Review of the Üllo Wine Purifier

Üllo Wine Purifier Review

Typically, in the production of wine, one of the greatest difficulties is associated with the unwanted microbial contamination of the beverage during the fermentation process. If you didn’t know by now, to obtain wine from grapes you have to transform the fructose of the grapes into ethyl alcohol.

Alcoholic fermentation is carried out by anaerobic yeasts, but in many cases, there are also other microorganisms that compete for the sugar, sometimes altering the fermentation process.

To eliminate these microorganisms, the best thing to do is to use sterile barrels and bottles. However, since this is not always possible, many wineries use sulfite, a preservative that interrupts the biological activity of the undesirable microorganisms.

Although the addition of sulfite improves the fermentation process, the preservative can have undesirable effects when consumed, such as bloating and other gastric issues or allergies.

To avoid these effects, it is advisable to remove sulfites from the wine before consuming it. But how to do this? On the market, there are several wine filters that claim they can remove sulfites from your favorite beverage, and Üllo Wine Purifier is probably the best of them.

Let’s find out more about this wine purifier system!

Things To Consider Before Buying A Wine Purifier

In the last years, there has been a constant debate among wine drinkers and wine makers about the presence of sulfites in the wine. Many consumers claim that sulfites are unhealthy and reduce the wine enjoying rate by creating gastric problems or headaches.

Nevertheless, the existence of sulfites in the wine, and eventually their elimination, is a much more complex problem than one might think. For this reason, before deciding to invest in a wine purifier, you should first understand where the issue is and decide whether you need a purifier or not.

If you have ever made your own wine at home, you probably know by now that sulfites in wine develop naturally. If you haven’t, then you should know that in many cases, especially when the wine is of a high quality and even more in the case of the aged reds, the wine contains natural sulfites that are a result of the activity of the yeasts.

Although natural sulfites exist in every bottle of wine, they rarely represent a problem. Natural sulfites are usually oxidized through decanting and they are usually not responsible for any collateral effects. In fact, many foods apart from wine, such as dry fruits and raisins, contain natural sulfites and they are still consumed without effects by adults and children alike.

The problem with the sulfites in wine arises when the winemakers add sulfur dioxide to the wine, a preservative usually referred to as sulfite.

According to the World Health Organization, industrial sulfites have harmful effects on our health, being responsible for the destruction of the thiamine, a vitamin from the group B. These sulfites can also cause allergic reactions and interact with cortisone medications.

As such, the elimination of the sulfites from the wine is recommended when consuming wines of a lower quality or if you decide to add sulfites to your wine to avoid the formation of bacteria.

A word should also be said about sulfites in wine and headaches. For a long time, many wine drinkers claimed that consuming any type of unpurified wine causes headaches. Again, while this might be true for the wines to which sulfite was added, the statement has no scientific base in the case of the high-quality wines that develop sulfites as a part of the natural fermentation process.

In fact, in a study published by the American Headache Association, headaches are only associated with red wine consumption and related to the presence of the phenolic flavonoid radicals rather than to the presence of sulfites.

Therefore, if you consume exclusively high-quality wines made by wineries that respect the original winemaking techniques and who don’t add any preservatives to their beverages, then investing in a wine purifier might be useless.

In fact, in this case, it is more recommended to invest in a good crystal decanter or in a wine aerator instead of a wine purifier.

On the contrary, if you like to buy a bottle or two of wine from the supermarket from time to time, then you might need to invest in a wine purifier. As a general rule, almost all wines available in the supermarkets have sulfites added in the fermentation process, and you might want to get rid of them before consuming the wine.

You might also need to invest in a wine purifier if you suffer from an allergy to sulfites, regardless of what type of wine you consume.

Lastly, if you don’t trust the American Headache Association, you might want to invest in a wine purifier just to make sure that the headaches you accuse are truly unrelated to the sulfites in the wine.

Regardless of the reason, if you decided that you need a wine purifier, you should know that one of the most revolutionary products on the market is Üllo.

What Is Üllo Wine Purifier?

Üllo is a revolutionary system designed to eliminate sulfites from the wine and to bring the beverage back to its natural state.

The idea of creating a wine purification system came to James Kornacki, a doctor in chemistry at the Northwestern University from Chicago, who, spurred by his sensitivity to sulfites, invented the Selective Sulfite Capture system that is able to remove the harmful chemical from any bottle of wine.

To remove sulfites, Üllo uses a special filter that captures sulfur dioxide alone, leaving the other compounds free to flow, improving in this way the organoleptic properties of the beverage. But how does Üllo work? In short, this high-tech filter has to be applied on the glass or carafe. Wine is poured through a system that is able to capture sulfites, improving the final taste of the wine.

The filters responsible for removing the sulfites are of single use and recommended to use with standard wine bottles of 750ml.

Apart from this, Üllo also acts as an aerator, therefore you will be able to have double benefits while using a single product. Of course, since the aeration is usually only recommended to red wines, Üllo also allows you to simply pour the wine without aerating it.

This wine purification system is designed to help all those who are allergic or sensitive to sulfites and, according to the inventor, the product satisfies both occasional tasters and the experienced consumers and wine experts, especially the sommeliers.

Apart from the technical specifications, Üllo also has a simple yet functional design that doesn’t compromise the excellence of the service. In fact, the wine purification system is stylish and elegant, therefore it can easily match with any environment while maintaining the class.

The shape of the system is thought to be compatible with a wide type of containers, including decanters, carafes, and stemware. Finding compatible glassware to use with Üllo is simple thanks to the standard design that fits almost all models, or you can choose to purchase the product with an especially designed carafe or decanter.

Features And Benefits

1. Remove Sulfites And Sediment

Üllo is designed to remove the sulfites as an added chemical preservative, aiming in this way to help to enjoy wine the dozens of wine lovers that suffer from sulfite sensitivity or allergy. In fact, many winemakers add sulfites to wine to properly store their beverage, but as soon as the bottle is opened, the sulfites are no longer needed.

To capture sulfites, Üllo uses a porous filter made of food-grade polymer and that is designed to capture exclusively the sulfites while maintaining the other compounds of the wine unaltered. This filter, named Selective Sulfite Capture, not only maintains the character of the wine while reducing sulfites, it actually improves the wine’s flavors.

Apart from capturing the sulfites, the filter is also able to remove the sediment, bringing in this way a further benefit. The removal of the sediment might not be necessary if you are only drinking white and sparkling wines, but it certainly is if you like to enjoy reds.

2. Triple System

The Üllo wine purifier is made of three distinct components that together have the power of removing the harmful chemicals from your wine, a cup, the filter and the aerator.

The cup is made of stain-resistant silicone and designed with a wide opening to help you pour the wine better. This cup is easy to maintain, it is easy to clean and dishwasher safe.

The second and probably the most important element of the wine purifier system is the filter, designed to capture sulfites and enclose them in an encapsulated polymer filter that has an aspect similar to a tea bag. Apart from the sulfites, the filter is also able to retain any sediment, ensuring that all the wine that reaches your glass is pure.

Lastly, the aerator is designed to enhance the bouquet and flavor of your red wines and functions essentially as any other aerator on the market. The difference between Üllo and the other products is that this wine purifier has a double function, not only that of aerating the wine.

The aerator can be easily turned off if its function is not needed, with a simple twist.

An attractive thing is also the design of the aerator, that causes the wine to flow in a visually delightful shape. The aerator is made of a BPA-free polymer that it is stain resistant and dishwasher safe.

The various parts of the system can be washed separately and the filter needs to be replaced after each use.

3. Improves The Taste Of The Wine

If you have ever tasted a bottle of high-quality wine and a bottle of supermarket wine at the same time, you might have noticed the distinctive bitter taste of the wine made for large-scale distribution. The bitter taste is caused by the sulfites and, unfortunately, it is often noticeable in cheaper wines.

Although many wine lovers might think that red wines have more sulfites, the things are usually different. In fact, winemakers use more sulfites to preserve the whites, that are more delicate compared to the reds and that lose their organoleptic characteristics in less time.

By removing the sulfites from the wine, Üllo improves its taste as it restores the wine’s flavor to the original ones. According to the manufacturer, the wine purifier system has been tested on a group of wine lovers who noticed a favorable difference in the taste of the white wines, while the system was also appreciated for its exceptional aeration capacity in regard to the red wines.

4. Universal Design

Üllo wine purifier has an attractive, minimalist design that matches well with any environment, but that is not its main characteristic.

The wine purification system is actually compatible with all stemware and with a great number of models of carafes and decanters.

To use the system you will only have to put the Üllo system on top of your glass, carafe, or decanter, and pour your wine through it. Simple and easy!

5. Silicone Base

The wine purification system is provided with a convenient silicone base that has a double function. First of all, the base is designed to capture any drops of wine that might drip from Üllo after use.

Secondly, the base acts as a showcase for the system when not in use and allows you to maintain it in hygienic conditions throughout serving.

What Do Users Say?

According to the users, Üllo wine purifier system is certainly able to improve the quality of the wine, regarding both the chemical composition and the taste.

The vast majority of the users claimed that their headaches and other side effects related to the consumption of sulfite additives dropped and even disappeared since using Üllo, while almost all of them appreciate the minimalist design and attractive shape.

Another thing highly appreciated is the cleaning ease and the fact that all the parts are dishwasher safe.

The only complaints regarding Üllo are related to its price, considered by many as excessive, especially because the purifier has single-use filters. For this reason, the users would appreciate either a reusable filter or a cheaper selling price.

Üllo Wine Purifier Alternatives

As mentioned above, a wine purifier might not be needed in all cases. Although we believe that having a wine purifier is an excellent idea for various reasons, we do understand that different people have different needs.

Therefore, if you think that Üllo is not for you, here are a few alternatives to consider.

1. Zazzol Wine Aerator Decanter

One of the most popular wine aerators on the market, Zazzol uses a multistage aeration process that is more effective than other systems available on the market. In fact, thanks to its unique design, the system aerates the wine in three steps, dispersing it over a cone that draining the liquid through 32 holes to then inject it into a tube before it reaches the glass.

This aeration system enhances the flavor of the wine and provides an improved balance.

  • The aerator design of the two systems are somehow similar, both systems using a cone shape to aerate the beverage.
  • Zazzol doesn’t have a filter to retain the sediment.
  • Because of the design, Zazzol cannot be placed on a glass or decanter but must be handheld while pouring.

2. Vinturi Essential Wine Aerator

Vinturi Essential Wine Aerator

Similar to Zazzol, Vinturi is another popular wine aerator appreciated for its exceptional characteristics. This system also uses a conic element to aerate the wine, but it draws oxygen into the beverage with the help of a patented technology that allows the system to draw in the air thanks to the difference in the pressure.


  • Vinturi is a handheld system and cannot be placed standing over a glass, carafe or decanter.
  • This wine aerator is not able to purify wine.
  • Vinturi comes at a more than affordable price which, compared to the Üllo, is a big plus if you don’t actually need a purifier.

3. Vintorio Wine Aerator Pourer

If you are looking for simplicity, Vintorio wine aerator pourer might be the product you are looking for, especially if you are only considering Üllo for its aeration features.

Vintorio is only an aerator, but it is extremely simple to use, it is comfortable and it does its job exceptionally well.

Vintorio Wine Aerator Pourer


  • Vintorio is a wine aerator and pourer that must be fixed to the neck of the bottle before pouring, while Üllo must be placed on the glass or decanter.
  • Vintorio is not able to retain sulfites or the sediment.
  • Vintorio has an anti-leak design that prevents wine drops from dropping, while Üllo has a base.


Considering that almost all wines have sulfites added as preservatives, Üllo wine purifier is an excellent addition to the accessory collection of any wine lover. It doesn’t really matter whether you are sensitive to sulfites or not, the added chemicals are still harmful and you should get rid of them.

Apart from the functional considerations, Üllo is aesthetically beautiful and it can be successfully used as an aerator.
