The Wand wine purifier, manufactured by PureWine Inc., represents an application of ion exchange technology to beverage treatment. The device has achieved distribution of over 8 million units and uses patented resin bead technology (US Patent #9,670,442 B2) to selectively reduce sulfite and histamine compounds in wine at the point of consumption.
The single-use filtration device employs ion exchange resins that bind to specific compounds while maintaining more than 95% of wine's tannins, phenolic compounds, and antioxidants according to independent laboratory testing.
Background: Sulfites and Histamines in Wine
Wine contains various naturally occurring compounds produced during fermentation. Sulfites form as byproducts of yeast fermentation and are also added as preservatives. The FDA requires "Contains Sulfites" labeling on wines exceeding 10 parts per million (ppm).
Histamines develop during fermentation through bacterial decarboxylation of histidine. Both sulfites and histamines exist in all wines regardless of price point, varietal, or production method.
Some individuals experience sensitivity to these compounds. According to published medical literature, sulfite sensitivity affects approximately 1% of the general population. Research examining histamine intolerance suggests prevalence of 1-3% of the population.
Traditional approaches to addressing sensitivities have included limiting wine consumption, selecting specific varieties, or avoiding wine entirely. The Wand represents an alternative approach: point-of-consumption treatment that targets specific compounds.

Technology Overview: Ion Exchange Mechanism
The Wand employs ion exchange resin technology, a well-established method used across water purification, food processing, and pharmaceutical applications. The device contains specialized resin beads formulated with both cation and anion exchange sites.
Technical Process
Ion exchange operates through selective binding. The resin beads contain functional groups engineered to preferentially bind sulfite and histamine molecules while allowing other wine compounds to remain in solution.
Cation exchange sites target positively charged molecules. At wine's typical pH range (3.0-3.8), histamine carries a positive charge, making it susceptible to binding by cation exchange resins containing negatively charged functional groups.
Anion exchange sites target negatively charged molecules. Sulfites exist primarily as bisulfite (HSO₃⁻) and sulfite (SO₃²⁻) ions at wine pH, which bind to positively charged functional groups in anion exchange resins.
The exchange process involves ionic substitution:
- Mineral ions initially bound to resin sites are released
- Target compounds (sulfites and histamines) bind to the vacated sites
- The resin retains bound compounds when removed from wine
Selective Binding Design
The resin formulation is engineered for selectivity. Independent laboratory analysis indicates the device maintains more than 95% of wine's tannins, phenolic compounds, and antioxidants while reducing target compounds.
This selectivity stems from the resin's functional group chemistry, pore size distribution, and exchange kinetics, which favor binding of sulfites and histamines over other wine components.
Independent Laboratory Analysis
The Wand has undergone testing at ETS Laboratories in St. Helena, California. ETS Laboratories is an ISO 17025-accredited facility specializing in wine analysis.
Laboratory testing protocols included:
- Sulfite Analysis: Standard analytical methods including iodometric titration to quantify free and total sulfite concentrations before and after treatment
- Histamine Measurement: High-performance liquid chromatography (HPLC) and related analytical techniques
- Compound Retention Analysis: Spectrophotometric and chromatographic methods to verify preservation of tannins, phenolics, and other compounds
- pH and Conductivity Monitoring: Measurement of physicochemical properties before and after treatment
According to laboratory reports, testing documented:
- Measurable reduction in sulfite concentrations in treated samples
- Measurable reduction in histamine levels in treated samples
- Wine pH maintained within ±0.5 units of pretreatment values

Scientific Context: Wine Chemistry and Individual Responses
Wine is a complex chemical matrix containing hundreds of compounds. Individual physiological responses to wine consumption vary based on multiple factors including:
- Genetic variations in metabolic enzymes
- Baseline sensitivity thresholds
- Consumption volume and rate
- Food pairing and hydration status
- Overall health status
Sulfite and histamine content represents two variables among many that influence individual wine experiences. Other compounds present in wine include:
- Alcohol (ethanol): Primary psychoactive component
- Tannins: Polyphenolic compounds from grape skins and oak aging
- Tyramines: Biogenic amines formed during fermentation
- Acetaldehyde: Oxidation product associated with wine aging
- Various organic acids: Contributing to wine's pH and flavor
The relationship between specific wine compounds and individual responses is an area of ongoing research in food science and nutrition.
Comparison with Alternative Approaches
Consumers seeking to optimize their wine experience have several available strategies:
Varietal Selection
Sulfite and histamine levels vary by wine type, grape variety, and production method. Red wines typically contain higher histamine concentrations than white wines due to extended maceration and malolactic fermentation.
However, compound levels can vary substantially between bottles of the same variety, making varietal selection an imprecise approach for individuals with specific sensitivities.
Production Method Awareness
Some producers emphasize minimal intervention winemaking or reduced sulfite additions. Terms like "low sulfite" or "no added sulfites" appear on some wine labels.
However, sulfites form naturally during fermentation, meaning "no added sulfites" wines still contain 10-20 ppm of naturally occurring sulfites. Additionally, production claims do not guarantee low histamine levels.
Organic and Biodynamic Wines
Organic certification relates to viticultural practices and limits added sulfites to 100 ppm (compared to 350 ppm for conventional wines). However, organic wines contain naturally occurring sulfites and histamines comparable to conventional wines.
Point-of-Consumption Treatment
The Wand represents a point-of-consumption approach that addresses sulfites and histamines simultaneously. Unlike production-level interventions, this method allows glass-by-glass treatment based on individual preference.
This approach enables consumers to treat wine regardless of production method, varietal, or origin without requiring advance knowledge of specific compound concentrations.
Materials Science: Resin Chemistry and Performance
The ion exchange resins employed in The Wand build on decades of materials science development in selective ion binding.
Resin Bead Composition
The device utilizes a mixed bed of cation and anion exchange resins. Cation exchange beads contain sulfonic acid functional groups in mineral form (potassium, calcium, or magnesium). Anion exchange beads contain quaternary ammonium functional groups in chloride form.
This mixed bed design serves multiple functions:
- Targets both positively and negatively charged compounds
- Maintains pH stability through balanced ion release
- Preserves wine conductivity at levels equal to or greater than untreated samples
Particle Size and Porosity
Resin beads measure approximately 200-300 microns in average diameter. This size range balances several performance factors:
- Sufficient surface area for rapid ion exchange kinetics
- Adequate mechanical strength to prevent bead fracture
- Appropriate flow characteristics for practical wine treatment
- Efficient packing density within the device housing
Bead porosity is engineered to facilitate compound diffusion into exchange sites while excluding larger molecules like tannins and anthocyanins.
Exchange Capacity and Saturation
Each device contains a predetermined quantity of resin beads calibrated for treating a 6-ounce wine serving. The exchange capacity is designed so that resin sites reach practical saturation after treating this volume, which is why the device is specified for single use.
Attempting to reuse a device would result in significantly reduced effectiveness as available exchange sites become occupied with bound compounds.

Frequently Asked Questions
How does treatment time affect compound reduction?
Laboratory testing indicates that sulfite and histamine reduction increases with contact time up to approximately 8-10 minutes. The recommended range of 3-8 minutes balances effectiveness with practical convenience.
Why is the device single-use?
Ion exchange resin capacity becomes saturated after treating a 6-ounce serving. Reuse would result in significantly reduced performance as exchange sites become occupied with previously bound compounds.
Does wine temperature matter?
Ion exchange kinetics are temperature-dependent, with slightly faster rates at room temperature. However, the device functions effectively across typical wine serving temperatures (45-68°F).
Can multiple devices treat a full bottle?
Yes. Treating larger volumes requires multiple devices proportional to the total volume. A standard 750ml bottle (25 ounces) would require approximately 4 devices for complete treatment.
Does the device work with organic wines?
Yes. All wines contain naturally occurring sulfites and histamines regardless of organic certification. Organic designation relates to viticulture practices and limits on added sulfites, not the absence of these naturally formed compounds.
What happens to the removed compounds?
Sulfites and histamines bind ionically to resin exchange sites and remain attached to the resin beads when the device is removed from wine. The bound compounds are disposed of with the device.
Can the device be used in restaurants?
The individually packaged format enables use in restaurants, bars, and other public settings. The treatment process requires 3-8 minutes of contact time with occasional stirring.
