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, sulfites into other noxious chemicals or indiscriminately remove sulfites along with several other compounds in the process. 

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

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

Please contact us through our website and we will be sure to contact you to resolve your issue.

It is pronounced, "ooo-low" :)

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.

Üllo is dishwasher friendly utilizing the top rack only, however, some newer dishwasher can run extremely hot, and will affect the upper silicone housing. In this case - handwashing is ideal. Ullo Chill™ is not recommended for use in the dishwasher.

Your Üllo and Chill™ Wine Purifiers separate into 4 pieces for cleaning.

Üllo filters are made from a sophisticated material often used in industrial food processing and pharmaceutical APIs (Active Pharmaceutical Ingredients). More 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. The filters are completely non-toxic, vegan, and gluten-free.

Each full bottle Selective Sulfite™ filter is good for one bottle of wine (750mL) and each Single Glass Selective Sulfite™ filter is good for one glass of wine (5 oz pour, 150 mL). Replacing the filter with each use comes as a consequence of filter’s unique surface chemistry. When you purify wine with Üllo, sulfites bind irreversibly to the filter. Once the filter becomes saturated with sulfites it can no longer bind additional sulfites from wine.

When stored properly, a partially used filter can be re-used the next day on the same bottle of wine, with minimal loss of efficacy. If you plan to use the filter for individual glasses 2 nights in a row, rinsing and refrigerating the filter can help to maintain its reactivity. 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 recommend using a new Selective Sulfite™ filter within three hours from 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. If you are someone that truly only drinks a glass every so often, a single glass filter is also available.

Cheers!

Some wines, after filtering, will take on a cloudy hue– this is the result of micro bubbles forming after the nano-filtration process and should dissipate quickly. If you see a sediment settling at the bottom of the glass post filtration, a broken filter, may be responsible. While the filter’s material is non-toxic, please discontinue drinking the glass of wine and email support@ullowine.com to request a replacement filter.

While rare, filters may occasionally be damaged during shipping, or when opening the filter package itself. Üllo will always replace broken, damaged, or defective filters at no cost. Please email support@ullowine.com to request a filter replacement for any damaged filters.

To maintain freshness, Selective Sulfite ™ filters are made form a food grade acrylic polymer that is naturally antimicrobial and therefore cannot be composted.

Ullo will work as an aerator without a Selective Sulfite™ Filter, but in order for Üllo to reduce sulfites in your wine, Selective Sulfite™ filters will need to be purchased and used.

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.

Since Üllo’s inception in 2015, we have continually tested the filters, and have found that when stored properly, there is no degradation of the filter. Once wetted, however, the filter will begin to lose activity.

The filter, in its entirety, is made with a food-grade safe polymer. It is also non-toxic, gluten-free, and vegan.

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.

No. Ullo was founded to solely remove sulfites from wine without disrupting the balance of naturally occurring compounds, like histamines.

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.

All orders placed Monday – Friday will ship within 2 days, however, it may take longer during periods of peak demand. Products purchased while they are “back-ordered” will take longer to ship.
