Üllo Open Wine Purifier — pour-through sulfite & histamine filter, 3 Selective Sulfite filters, adjustable aeration

Üllo Open is a pour-through wine purifier that removes sulfites and lowers histamines while also letting you dial in aeration for a cleaner, truer glass of wine as soon as you open the bottle.

Designed for people who want better-tasting wine without altering its natural balance, the Üllo Open combines a patented selective filtration system with an adjustable aerator in a single handheld device. It sits on top of any wine glass, filters as you pour, and the included three Selective Sulfite filters are made from a food-grade polymer in the USA. The unit’s soft-touch silicone body is BPA-free and made to last, while the lid doubles as a drip-catcher when placed on a tabletop.

How does Üllo Open improve the flavor of opened wine?

Üllo Open uses a targeted polymer filter that captures free sulfites the moment wine is poured, allowing the wine’s natural aromas and flavors to shine through without stripping its structure. The process avoids chemical additives and works instantly while preserving the wine’s intended acidity and mouthfeel.

• Selective polymer filter removes free sulfites during pouring
• Preserves the wine’s chemistry for authentic flavor
• Made to act as soon as the bottle is opened—no soaking needed

Can Üllo Open reduce wine-related sensitivities like headaches?

Üllo Open targets free sulfites and can reduce certain biogenic amines such as histamines that some people associate with sensitivity symptoms. Results vary by individual and by wine composition, so while many users report fewer adverse reactions, outcomes aren’t guaranteed for everyone.

• Reduces free sulfites linked to some sensitivities
• Helps lower histamine levels in some wines
• Non-invasive approach—does not add or chemically alter wine

How do I control aeration for different wines?

The Open features a fully adjustable aeration dial that lets you set airflow to suit the wine style and your palate. Turn aeration off for delicate whites, choose medium for lighter reds, and open it fully for rich, bold wines to soften tannins and reveal broader aromatic profiles.

• Slider adjusts air intake from closed to fully open
• Simple settings recommended for whites, light reds, and full-bodied reds
• Easy to change on the fly while pouring

What about care, filter replacement, and build quality?

Üllo Open is built with BPA-free silicone for a durable, soft-touch finish and is easy to disassemble for cleaning. Filters are user-replaceable and sold separately; each filter is a patented, food-grade polymer manufactured in the USA to maintain consistent performance.

• Soft-touch, BPA-free silicone body for longevity and grip
• Filters snap in/out for quick replacement and minimal downtime
• Lid doubles as a drip-catcher and base for neat serving

Who this product is for: Üllo Open is ideal for wine lovers who want a purer tasting experience right from the first pour—especially those sensitive to sulfites or histamines, home entertainers looking for a fuss-free tool to improve open bottles, and anyone who wants adjustable aeration without decanting. It’s for people who prefer a simple pour-over solution that respects the wine’s structure and aroma while offering easy upkeep and reliable materials.
