Explaining Counterfeit Alcohol Purchases in Russia

Uncovering the Counterfeit: A study of whiskey authenticity through volatile organic compound fingerprinting, aroma and color sensory analysis

This study presents a method employing gas chromatography coupled with mass spectrometry and headspace solid-phase microextraction (HS-SPME-GC-MS), supplemented with chemometrics (Soft independent modelling of class analogies - SIMCA), to analyze volatile organic compound (VOCs) profiles in suspect whiskey samples. Furthermore, a sensory analysis of aroma and color was conducted with a panel of 52 non-trained volunteers to evaluate their ability to discriminate and preference for counterfeit whiskeys. The HS-SPME-GC-MS method successfully distinguished 41 seized samples from authentic beverages. Interestingly, sensory analysis revealed that panelists could differentiate between counterfeit and authentic samples with a reference standard but did not consistently show a preference for aroma. In some cases, there was even a preference for the color of counterfeit whiskeys. The findings suggest that sensorial tests alone may not effectively distinguish counterfeit from authentic whiskeys, especially for non-expert consumers, highlighting the need for analytical instrumentation methods in fraud detection.

Design of a Novel Auxiliary Diagnostic Test for the Determination of Authenticity of Tequila 100% Agave Silver Class Based on Chemometrics Analysis of the Isotopic Fingerprint of the Beverage

The present research shows a robust isotopic ratio characterization of Carbon-13 (δ¹³C_VPDB) in congeneric compounds such as methanol, n-propanol, isoamyl alcohol, ethyl lactate, ethyl acetate, ethanol, and acetaldehyde in representative samples (n = 69) of Tequila 100% agave silver class (TSC), employing gas chromatography/combustion/isotope-ratio mass spectrometry (GC/C/IRMS). From the information obtained, the construction of a radial plot attributable to the isotopic fingerprint of TSC was achieved. With this information, a diagnostic test was designed to determine the authenticity of TSC, comparing alcoholic beverages from other agave species as non-authentic samples. The sensitivity of the test was 94.2%; the specificity was 83.3%. Additionally, non-authentic samples were analyzed that meet all the criteria established in the regulations. The results obtained show that the GC/C/IRMS analytical technique and designed diagnostic test are useful as auxiliary parameters to determine the authenticity of the beverage, thus managing to determine the adulteration or falsification of the product.

Development of a Predictive Model for Agave Prices Employing Environmental, Economic, and Social Factors: Towards a Planned Supply Chain for Agave-Tequila Industry

The interest of consumers to acquire Tequila has caused an increase in its sales. As demand increases, the Tequila industry must obtain its raw material at a constant rate and agave farmers must be prepared to satisfy this supply chain. Because of this, modernization of the strategies used to ensure a planned, scheduled, timely, and predictable production will allow farmers to maintain the current demand for Tequila. This has been evidenced in official historical records from 1999 to 2020 where there is a fluctuation in the price of agave due to supply and demand. Given this scenario, this research shows the development of a multivariable predictive mathematical model that will permit the agave−Tequila production chain to work based on a smart implementation of planned actions to guarantee the agave supply to the Tequila industry. The proposed model has a goodness of fit (R = 0.8676; R¯2 = 0.8609; F(1,20) = 131.01 > F0.01 (1,20) = 8.10) and demonstrates the impact on agave prices is due to several factors: Tequila exports (α = 0.50) > agave plants harvested “jima” (α = 0.44) > dollar exchange (α = 0.43) > Tequila production (α = 0.06) > annual accumulated precipitation (α = 0.05). Nevertheless, the price forecast can be influenced by climate change or economic crises that affect the supply chain. In conclusion, a prediction of agave price stabilization for five years is shown where authorized producers can evaluate future scenarios so that the agave supply chain can be guaranteed for Tequila production, facilitating the decision making regarding its raw material.

The impact of alcohol taxation changes on unrecorded alcohol consumption: A review and recommendations

BACKGROUND

The diverse forms of unrecorded alcohol, defined as beverage alcohol not registered in official statistics in the country where it is consumed, comprise about one fourth of all alcohol consumed worldwide. Since unrecorded alcohol is usually cheaper than registered commercial alcohol, a standard argument against raising alcohol excise taxes has been that doing so could potentially result in an increase in unrecorded consumption. This contribution examines whether increases in taxation have in fact led to increases in consumption of unrecorded alcohol, and whether these increases in unrecorded alcohol should be considered to be a barrier to raising taxes. A second aim is to outline mitigation strategies to reduce unrecorded alcohol use.

METHODS

Narrative review of primary and secondary research, namely case studies and narrative and systematic reviews on unrecorded alcohol use worldwide.

RESULTS

Unrecorded alcohol consumption did not automatically increase with increases in taxation and subsequent price increases of registered commercial alcohol. Instead, the level of unrecorded consumption depended on: a) the availability and type of unrecorded alcohol; b) whether such consumption was non-stigmatized; c) the primary population groups which consumed unrecorded alcohol before the policy change; and d) the policy measures taken. Mitigation strategies are outlined.

CONCLUSIONS

Potential increases in the level of unrecorded alcohol consumption should be considered in the planning and implementation of substantial increases in alcohol taxation. However, unrecorded consumption should not be considered to be a principal barrier to implementing tax interventions, as evidence does not indicate an increase in consumption if mitigation measures are put in place by governments.

What's in this drink? Classification and adulterant detection in Irish Whiskey samples using near infrared spectroscopy combined with chemometrics

BACKGROUND

Near-infrared (NIR) spectroscopy coupled with principal component analysis (PCA) and partial least squares (PLS) regression was used to analyse a series of different Irish Whiskey samples in order to define their spectral profile and to assess the capability of the NIR method to identify samples based on their origin and storage (e.g. distiller, method of maturation). The ability of NIR spectroscopy to quantify the level of potential chemical adulterants was also investigated. Samples were spiked with 0.1%, 0.5%, 1.0%, 1.5% and 2.0% v/v of each adulterant (e.g. methanol, ethyl acetate, etc.) prior to NIR analysis.

RESULTS

The results of this study demonstrated the capability of NIR spectroscopy combined with PLS regression to classify the whiskey samples and to determine the level of adulteration. Moreover, the potential of NIR coupled with chemometric analysis as a rapid, portable, and non-destructive screening tool for quality control, traceability, and food/beverage adulteration for customs and other regulatory agencies, to mitigate beverage fraud was illustrated.

CONCLUSION

Given the non-specificity of the NIR technique, these positive preliminary results indicated that this method of analysis has the potential to be applied to identify the level of adulteration in distilled spirits. The rapid nature of the technique and lack of consumables or sample preparation required allows for a far more time and cost-effective analysis per sample. © 2021 Society of Chemical Industry.

Russia's National Concept to Reduce Alcohol Abuse and Alcohol-Dependence in the Population 2010-2020: Which Policy Targets Have Been Achieved?

In the 2000s, Russia was globally one of the top 5 countries with the highest levels of alcohol per capita consumption and prevailing risky patterns of drinking, i.e., high intake per occasion, high proportion of people drinking to intoxication, and high frequency of situations where alcohol is consumed and tolerated. In 2009, in response to these challenges, the Russian government formed the Federal Service for Alcohol Market Regulation and published a national strategy concept to reduce alcohol abuse and alcohol-dependence at the population level for the period 2010-2020. The objectives of the present contribution are to analyze the evidence base of the core components of the concept and to provide a comprehensive evaluation framework of measures implemented (process evaluation) and the achievement of the formulated targets (effect evaluation). Most of the concept's measures were found to be evidence-based and aligned with eight out of 10 areas of the World Health Organization (WHO) policy portfolio. Out of the 14 tasks, 7 were rated as achieved, and 7 as partly achieved. Ten years after the concept's adoption, alcohol consumption seems to have declined by about a third and alcohol is conceptualized as a broad risk factor for the population's health in Russia.

A Brief History of Whiskey Adulteration and the Role of Spectroscopy Combined with Chemometrics in the Detection of Modern Whiskey Fraud

Food fraud and adulteration is a major concern in terms of economic and public health. Multivariate methods combined with spectroscopic techniques have shown promise as a novel analytical strategy for addressing issues related to food fraud that cannot be solved by the analysis of one variable, particularly in complex matrices such distilled beverages. This review describes and discusses different aspects of whisky production, and recent developments of laboratory, in field and high throughput analysis. In particular, recent applications detailing the use of vibrational spectroscopy techniques combined with data analytical methods used to not only distinguish between brand and origin of whisky but to also detect adulteration are presented.

Is There a Need for Alcohol Policy to Mitigate Metal Contamination in Unrecorded Fruit Spirits?

Unrecorded alcohol comprises all types of alcohol that is not registered in the jurisdiction where it is consumed. In some countries in Central and Eastern Europe as well as the Balkans, the majority of unrecorded alcohol consumption may derive from the home production of fruit spirits. Some studies found a high prevalence of lead and cadmium in such spirits. This article provides a quantitative comparative risk assessment using the margin of exposure (MOE) methodology for lead and cadmium, compared to ethanol, for unrecorded fruit spirits. For average concentration levels, the lowest MOE (0.8) was calculated for ethanol (alcohol itself). For lead, the MOE was 13 for moderate daily drinking and 0.9 for the worst-case scenario. For cadmium, the MOE was 1982 for moderate daily drinking and 113 for the worst-case scenario. The results of this study are consistent with previous comparative risk assessments stating that ethanol itself comprises by far the highest risk of all compounds in alcoholic beverages. Regarding metal contaminants, the risk of cadmium appears negligible; however, lead may pose an additional health risk in heavy drinking circumstances. Strategies to avoid metal contamination in the artisanal home production of spirits need to be developed.

Perception of alcohol policies by consumers of unrecorded alcohol - an exploratory qualitative interview study with patients of alcohol treatment facilities in Russia

Background

Over the last decade Russia has introduced various policy measures to reduce alcohol consumption and alcohol-related harm at the population level. Several of these policies, such as higher pricing and taxation or restrictions of availability, may not work in the case of unrecorded alcohol consumption; they may encourage consumers to switch to unrecorded alcohol and even increase consumption. In the present qualitative interview study we explore the perception of the recently implemented alcohol policies by patients diagnosed with alcohol dependence in two Russian cities in the years 2013–2014 and shed light on possible entry-points to prevention.

Methods

Semi-structured in-depth expert interviews were conducted with 25 patients of state-run drug and alcohol treatment centers in two Russian cities in 2013 and 2014. The interviews were analyzed using thematic content analysis.

Results

All of the interviewed participants have consumed unrecorded at some point with the majority being regular consumers, mostly switching between recorded and unrecorded alcohol depending on the situation, as predominantly defined by available money and available sources of alcohol. Low price and high availability were reported as the main reasons for unrecorded consumption. Participants voiced a general mistrust of the recently implemented alcohol regulations and viewed them largely as ineffective. They expressed particular concerns over price increases and restriction of night sales of alcoholic beverages. Substantial shifts within the unrecorded alcohol market were reported, with a decreasing availability of home-made beverages in favor of alcohol surrogates in the form of non-beverage alcohol, medicinal and cosmetic compounds. At the same time consumption of home-made alcoholic beverages was seen as a strategy to avoid counterfeit alcohol, which was frequently reported for retail sale.

Conclusions

Despite the alcohol policy changes in the last years in Russia, consumption of unrecorded alcohol remained common for people with alcohol dependence. Reduction of availability of unrecorded alcohol, first and foremost in the form of cheap surrogates, is urgently needed to reduce alcohol-related harm. Implementation of screening and brief interventions for excessive alcohol consumption in various contexts such as primary healthcare settings, trauma treatment services or the workplace could be another important measure targeting consumers of unrecorded alcohol.

Effectiveness of policy changes to reduce harm from unrecorded alcohol in Russia between 2005 and now

BACKGROUND

Consumption of unrecorded alcohol (alcohol that is not taxed and reflected in official statistics, but consumed as a beverage) has been identified as one of the main contributors to alcohol-attributable premature mortality in Russia. The problem was highlighted by a recent a mass poisoning with surrogate alcohol occurred in the Siberian city of Irkutsk.

METHODS

Based on key publications and legislative documents, a narrative review was undertaken about alcohol-related harm reduction policies in Russia for the period between 2005 and 2017, as well as the impact of these policies on the recorded and unrecorded alcohol consumption and alcohol market.

RESULTS

Various policy measures mainly targeting availability and price of recorded and unrecorded alcohol have been introduced since 2005, which generally coincided with the decreases in alcohol-related mortality observed at that time. However, regulations on medicinal and cosmetic products have remained inconsistent providing the foundations for the continued existence of a legal industry of surrogates with broad availability and misuse.

CONCLUSION

The Russian experiences of introducing alcohol policies demonstrate that there are effective measures to reduce unrecorded alcohol consumption and attributable harm. The government's multi-level strategy of alcohol consumption and harm reduction should be pursued stringently and all the possible loop-holes for producers, sellers and distributors of illegal and/or unrecorded alcohol should be eliminated or at least critically reduced.

Detection of counterfeit brand spirits using 1H NMR fingerprints in comparison to sensory analysis

Beverage fraud involving counterfeiting of brand spirits is an increasing problem not only due to deception of the consumer but also because it poses health risks e.g. from possible methanol admixture. Suspicious spirit samples from Russia and Kenya were analysed using ¹H nuclear magnetic resonance (NMR) spectroscopy in comparison to authentic products. Using linear regression analysis of spectral integral values, 4 counterfeited samples from Russia and 2 from Kenya were easily identifiable with R² < 0.7. Sensory analysis using triangle test methodology confirmed significant taste differences between counterfeited and authentic samples but the assessors were unable to correctly identify the counterfeited product in the majority of cases. An important conclusion is that consumers cannot assumed to be self-responsible when consuming counterfeit alcohol because there is no general ability to organoleptically detect counterfeit alcohol.

The internet trade of counterfeit spirits in Russia - an emerging problem undermining alcohol, public health and youth protection policies?

Counterfeit alcohol belongs to the category of unrecorded alcohol not reflected in official statistics. The internet trade of alcoholic beverages has been prohibited by the Russian Federation since 2007, but various sellers still offer counterfeit spirits (i.e., forged brand spirits) over the internet to Russian consumers, mostly in a non-deceptive fashion at prices up to 15 times lower than in regular sale. The public health issues arising from this unregulated trade include potential harm to underage drinkers, hazards due to toxic ingredients such as methanol, but most importantly alcohol harms due to potentially increased drinking volumes due to low prices and high availability on the internet. The internet sale also undermines existing alcohol policies such as restrictions of sale locations, sale times and minimum pricing. The need to enforce measures against counterfeiting of spirits, but specifically their internet trade should be implemented as key elements of alcohol policies to reduce unrecorded alcohol consumption, which is currently about 33 % of total consumption in Russia.
