Anticipating consumer preference for low-alcohol wine: a machine learning analysis based on consumption habits and socio-demographics

Abstract

The global wine consumption landscape is undergoing a transformation, marked by a growing trend towards reduced consumption and a preference for healthier lifestyles. However, comprehensive studies investigating consumer preferences for low-alcohol wine remain scarce. This study aims to anticipate consumer preference for low-alcohol wine based on consumers wine consumption habits and their socio-demographics. The data were collected from 2022 to 2024 through online surveys to consumers in France, Germany, Italy and the United States, the four largest wine-consuming countries in 2021. The survey comprised questions regarding consumers’ socio-demographics, wine consumption habits and preference for alcoholic content of wine. We employed various machine learning algorithms, treating each survey year as a repetition to identify the best modeling approach. After evaluating the performance of these models, Random Forest emerged as the top performer. The analysis revealed that interactions between socio-demographic factors and buying habits factors are significant predictors of low-alcohol wine preferences. The study provides actionable insights for wine producers and marketers, offering a data-driven approach to more effectively target low-alcohol wine markets using accessible customer data such as demographics and sales records.

Anticipando la preferencia del consumidor por el vino bajo en alcohol: un análisis de aprendizaje automático basado en los hábitos de consumo y las  características socio-demográficas 

Objetivos y alcance: el panorama global del consumo de vino está experimentando una transformación, marcada por una tendencia creciente hacia un consumo reducido y una preferencia por estilos de vida más saludables. En línea con este cambio, la regulación de la unión europea (regulación UE 2021/2117) ha redefinido recientemente el vino desalcoholizado o parcialmente desalcoholizado dentro de la categoría del vino. Sin embargo, los estudios completos que investigan las preferencias del consumidor por el vino bajo en alcohol siguen siendo escasos. Este estudio tiene como objetivo anticipar la preferencia del consumidor por el vino bajo en alcohol basándose en los hábitos de consumo de vino de los consumidores y sus características socio-demográficas. Metodología: a través de una revisión exhaustiva de las investigaciónes relevantes publicadas, identificamos las principales características de los hábitos de consumo y exploramos el papel mediador de las características socio-demográficas en la influencia de las preferencias del consumidor. Los datos se recogieron de 2022 a 2024 mediante el envío de encuestas en línea a consumidores en Francia, Alemania, Italia y Estados Unidos, los cuatro países con mayor consumo de vino según la organización internacional de la viña y el vino (OIV). La encuesta incluyó preguntas sobre las características socio-demográficas de los consumidores, los hábitos de consumo de vino y la preferencia por el contenido alcohólico del vino. Empleamos diversos métodos de aprendizaje automático, tratando cada año de encuesta como una repetición para identificar el mejor enfoque de modelado. Después de evaluar el rendimiento de estos métodos, las máquinas de reforzamiento de gradiente (gbm) surgieron como las más destacadas. Resultados e implicaciones: mediante la modelización gbm, descubrimos que las interacciones entre los hábitos de consumo y las características socio-demográficas ejercían una mayor influencia que los hábitos de consumo solos en la preferencia del consumidor por el vino bajo en alcohol. Específicamente, las interacciones entre el país de residencia de los encuestados y la frecuencia de compra de vino, así como entre la ocupación y la frecuencia de compra de vino tinto y blanco, surgieron como factores relativamente más influyentes. En particular, las personas de alemania que raramente compraban ciertos tipos de vino mostraron una fuerte preferencia por las variedades bajas en alcohol, al igual que aquellos que actualmente no estaban empleados y compraban vino tinto o blanco mensualmente. Nuestro estudio subraya la importancia de considerar tanto los hábitos de consumo como los factores socio-demográficos para comprender las preferencias del consumidor por el vino bajo en alcohol. Comprender estas dinámicas puede informar estrategias dirigidas para la producción, comercialización y promoción de variedades de vino bajo en alcohol para satisfacer las cambiantes demandas y preferencias del consumidor.

Anticipando le preferenze dei consumatori per il vino a basso contenuto alcolico: un’analisi machine learning basata sulle abitudini di consumo e sulle caratteristiche socio-demografiche

Obiettivi e ambito: il panorama globale del consumo di vino sta subendo una trasformazione, contraddistinta da una tendenza crescente verso un consumo ridotto e una preferenza per stili di vita più sani. In linea con questo cambiamento, il regolamento dell’unione europea (regolamento UE 2021/2117) ha recentemente ridefinito il vino dealcolizzato o parzialmente dealcolizzato all’interno della categoria del vino. Tuttavia, studi completi che indaghino sulle preferenze dei consumatori per il vino a basso contenuto alcolico rimangono scarsi. Questo studio mira ad anticipare le preferenze dei consumatori per il vino a basso contenuto alcolico basandosi sulle abitudini di consumo del vino dei consumatori e sulle loro caratteristiche socio-demografiche. Metodologia: attraverso un’ analisi bibliografica estesa, abbiamo identificato le principali caratteristiche delle abitudini di consumo e esplorato il ruolo delle caratteristiche socio-demografiche nell’influenzare le preferenze dei consumatori. I dati sono stati raccolti dal 2022 al 2024 inviando sondaggi online ai consumatori in Francia, Germania, Italia e Stati Uniti, i quattro paesi con il maggior consumo di vino secondo l’organizzazione internazionale della vite e del vino (OIV). Il sondaggio comprendeva domande riguardanti le caratteristiche socio-demografiche dei consumatori, le abitudini di consumo del vino e la preferenza per il contenuto alcolico del vino. Abbiamo utilizzato vari metodi di machine learning, trattando ogni anno del sondaggio come una ripetizione per identificare l’approccio di modellizzazione migliore. Dopo aver valutato le performance di questi metodi, le gradient boosting machines (gbm) sono emerse come le più performanti. Risultati e implicazioni: abbiamo individuato che le interazioni tra le abitudini di consumo e le caratteristiche socio-demografiche esercitavano una maggiore influenza rispetto alle sole abitudini di consumo sulla preferenza dei consumatori per il vino a basso contenuto alcolico. In particolare, le interazioni tra il paese di residenza dei rispondenti e la frequenza degli acquisti di vino, così come tra l’occupazione e la frequenza degli acquisti di vino rosso e bianco, sono emerse come fattori relativamente più influenti. In particolare, gli individui provenienti dalla germania che acquistavano raramente certi tipi di vino manifestavano una forte preferenza per le varietà a basso contenuto alcolico, così come coloro che non lavoravano e acquistavano mensilmente vino rosso o bianco. Il nostro studio sottolinea l’importanza di considerare sia le abitudini di consumo che i fattori socio-demografici per comprendere le preferenze dei consumatori per il vino a basso contenuto alcolico. Comprendere queste dinamiche può informare strategie mirate per la produzione, il marketing e la promozione delle varietà di vino a basso contenuto alcolico per soddisfare le mutevoli esigenze e preferenze dei consumatori.

Evidence of successful wine business strategies: customer acquisition, value or retention?

This presentation illustrates a series of successful wine businesses, which have managed to counter the downward trend impacting the global industry. How these businesses have been successful is explained through the planning and execution of strategies that focused on a clear and consistent aim in attracting new consumers. These cases add weight to the ehrenbergian position that for a business to be successful it must target new customers as a priority over alternative options like increasing value or improving customer retention.

Agri-photovoltaics: first experience above Riesling vines

Agri-photovoltaics (apv) describes the dual use of an agricultural area for food production and solar power generation. There are already a number of systems in operation around the world with various crops and under a wide range of different set-ups. In large parts, they still allow mechanical cultivation and other positive side effects of an APV system were observed in addition to the increase in utilization in the form of electricity and food: effects on the water balance and passive protection against extreme weather events.

Effect of moderate wine consumption in animal models

In 1979, the so-called “french paradox” was proposed, that is, a correlation between wine consumption, a diet rich in saturated fats, and a low mortality from coronary heart disease. On the other hand, it has also been described that alcohol consumption has negative effects on aging and increases the risk of liver cirrhosis and cancer. However, both hypotheses are based on population studies that may present distortions due to multiple factors (geographic, diet, smoking, socioeconomic level, etc.).

Evaluation of the efficiency of dialysis membranes in the wine dealcoholization process

The global wine production is continuously evolving to meet the new demands and preferences of consumers. in this evolving scenario, it’s important to determine which trends will be short-lived and which will remain over time. The promotion of healthier habits has encouraged consumers to try to find alternatives with low or no alcohol content. The challenge for the industry is to produce an alcohol-free wine that retains the familiar aromas and mouthfeel of traditional wine but without alcohol. Ethanol is the most abundant compound in wine, excluding water.

Role of PH and its management during vinification on the extraction during maceration and on the evolution during ageing of the phenolic compounda of red wine

Climatic changes cause significant variations in the composition of grapes. for red grapes, a mismatch between phenolic and technological ripening is often observed. There is also often a marked increase in pH and a reduction in fixed acids, which affect the stability and evolution of the wine during ageing. These experiments will provide more information on the role of pH during the winemaking of red wines on the extraction and evolution of phenolic compounds.
