Sulfites have a distinctly harsh, bitter taste that is often noticeable in wine. Although levels vary, white wines tend to have more sulfites than reds. Preliminary taste tests show that a majority of tasters notice a difference.

Üllo will remove sulfites from ANY BEVERAGE, including hard ciders and champagne, but the purification process may reduce carbonation and take longer for carbonated beverages. 

For this reason, carbonated beverages are not recommended for purification with Üllo.

Üllo is the only product that can remove sulfites selectively. Other products simply convert (or oxidize if you love chemistry terms) sulfites into other noxious chemicals or remove sulfites along with several other compounds in the process. 

The selectivity of Üllo's filters means that they won't harm the flavor or aroma compounds in your wine – a significant benefit if you are a wine lover. 

The Üllo is designed to sit perfectly on any glass, making it the perfect accessory to any wine, any time.

We are so sorry to hear that you are having issues with your Üllo!

Üllo filters are made from a sophisticated material often used in industrial food processing and pharmaceutical APIs (Active Pharmaceutical Ingredients). Specifically, The filter is made from a food-grade, macroporous acrylic polymer. When activated, it captures free sulfites in wine by a reaction called covalent attachment.

Each Üllo Selective Sulfite Capture Filter^TM is good for one bottle of wine (750ml). This is a consequence of the chemistry of the filter. Sulfites bind irreversibly to the filter and therefore once a filter becomes saturated with sulfites it can no longer bind additional sulfites from wine.

We know it’s not always practical to finish a bottle of wine in one evening. We also know that filters are precious commodities! We have found that, when stored properly, a partially used filter can be re-used the next day on the same bottle of wine, with little loss of efficacy. Rinsing and refrigerating the filter can help to maintain its reactivity, so please follow the steps below before attempting to reuse a filter.

Step 1 : Rinse the filter under cold water for at least 5 seconds

Step 2 : Refrigerate the filter uncovered so the filter can dry

Step 3 : Reuse the filter to purify your remaining wine within 24 hours

For best results, we still recommend using a new Selective Sulfite Capture™ filter after three hours since its first use. This is because the surface of the filter is reactive and becomes “activated” when it gets wet with wine. During purification, the activated filter weakly interacts with the tannins in wine through a process called non-specific adsorption. Rinsing the filter helps to keep the filter active, for the same reason that washing a red wine stain before it dries keeps the stain from setting in. 

Cheers!

Yes, Üllo will work as an aerator even without a Selective Sulfite Capture(TM) Filter.

To see the aerating function in action, check out this video

For best storage, filters should not be exposed to high heat and should not be left open to air before use.

Yes! The filter material is made with a food-grade safe polymer.

Sulfites are artificial chemicals added to wine as a preservative. They are a highly regulated food additive because they are common food allergens and are toxic at high levels. Sulfites protect wine against oxidation and bacterial spoilage during shipping and storage but are no longer needed once you open the bottle.

Üllo purifies wine using a sophisticated polymer to selectively bind sulfites, while allowing other compounds in wine to flow through unaffected. Through Selective Sulfite Capture™, sulfites are reduced to a more naturally occurring level in most wines.

Üllo comes ready to use. However, we recommend giving the Üllo purifier a quick rinse with water before the first use. 

 For more information on how to clean your Üllo, click here!

For best results, simply rinse the Üllo purifier under warm water to remove most of the wine residue. Soaking the Ülllo in hot, soapy water will remove any dried on wine.

Yes, but it is recommended to use top rack only.

Most wines will take between 2-4 minute to filter a whole bottle. If the filtration process is taking longer, this is likely due to carbonation. While dissolved carbon dioxide is noticeable in some wines, sparkling wines and Champagne being the most obvious, many wines have trace amounts of dissolved carbon dioxide. 

The dissolved carbon dioxide will form small bubbles inside the Selective Sulfite Capture™ filter and slow the flow of wine. Üllo is still removing sulfites, but it will take significantly longer to purify the wine.

Normally, most orders will process and be in our system within 1-2 business days. During times of peak demand it may take longer.
