Análise comparativa do consumo no serviço de open bar em três tipos de eventos distintos

Abstract

This study aims to analyse and compare consumption in open bar services across three distinct types of events—graduation parties, weddings, and birthdays—seeking to understand how these variations impact costs and operational planning. To this end, a quantitative study was conducted based on a sample of 46 events from a company specialising in open bar cocktail services, located in the city of João Pessoa, between December 2024 and September 2025. The data were analysed using descriptive statistics and analysis of variance (ANOVA), supported by SPSS software, in order to identify significant differences among the groups examined. The results indicate that beverage consumption varies significantly according to the type of event, constituting the primary cost driver of the service. In contrast, fruit consumption exhibited low variability and did not demonstrate a relevant influence on total costs, regardless of event type. These findings reveal the existence of distinct consumption patterns, enabling the open bar cost structure to be understood through two dimensions: a behavioural dimension, associated with beverages, and an operational dimension, related to complementary inputs. As a practical implication, the study contributes to the improvement of service planning and management by supporting the development of more robust strategies aligned with the specific characteristics of each type of event.
