Consumer attitudes and sensory perceptions of wine : a South African cross-cultural study
Thesis (PhDAgric)--Stellenbosch University, 2018.ENGLISH ABSTRACT: The wine consumer landscape has changed in South Africa since 1994. Historically, some
population groups had more access and greater cultural affinity for the product âwineâ, but such
historical patterns are rapidly changing, particularly in urban areas. South Africa has a low per
capita wine consumption, but industrial research has shown that there is potential for growth.
The wine industry is therefore aiming to become more consumer-driven, in order to increase
domestic wine consumption. Consequently, the need for consumer research has increased.
Only limited published data is available on South African wine consumers and their
consumption habits.
The general aim of this study was therefore to do a broad exploration of current wine
consumersâ perceptions of wine. This study had a few objectives, firstly to use focus groups to
obtain a better understanding of South African wine consumers from different ethnic
backgrounds (Black African and Caucasian), with a focus on perceptions, style preferences,
context of enjoyment, purchase and consumption patterns, and journeys towards wine
consumption. Secondly to develop a questionnaire in order to investigate motivations for wine
consumption on a larger scale. Thirdly to compare consumersâ, trained assessors, and industry
professionalsâ sensory perceptions of wine. Lastly to look at the influence of cultivar name on
consumer liking.
The results of the focus groups showed that the predominant differences occurred between
male and female consumers. With regards to ethnicity, this study did not reflect a large
distinction between the different ethnic groups.
Overall, the wine choice questionnaire showed motivations for drinking wine between the
consumer groups to be similar. The social, sensory appeal and ethical concern factors were the
three most important motivational factors for South African wine consumers.
The industry professionals, trained assessors, and consumers gave very similar answers and
distinguished between the sample set of wines in a similar fashion. Consumers that participated
in this study mostly described themselves as novices and only somewhat knowledgeable. For
them, knowing the cultivar name did not significantly change the way they described the
samples, nor did it significantly alter their liking. Even though the samples were all different
cultivars made in different styles, on average they were all received positively.
This is the first study to focus on understanding the changed landscape of SA wine consumers.
The knowledge gained made a significant contribution towards a better understanding of South
African consumersâ perceptions of wine, and also highlights directions for future studies.AFRIKAANSE OPSOMMING: Die wynverbruikersprofiel in Suid-Afrika het verander sedert 1994. Histories het sekere
populasiegroepe meer toegang en ân groter kulturele affiniteit tot die produk âwynâ gehad, maar
hierdie neiging verander tans vining, veral in stedelike gebiede. Suid-Afrika het ân lae per kapita
wynverbruik, maar industriële navorsing toon dat daar potensiaal is vir groei. Daarom strewe die
wynindustrie daarna om meer verbruikersgedrewe te raak om sodoende huishoudelike
wynverbruik te verhoog. Gevolglik het die behoefte aan wynverbruikersnavorsing toegeneem.
Daar is tans ân beperkte aantal gepubliseerde artikels oor Suid-Afrikaanse wynverbruikers se
persepsies en hul verbruikersgewoontes.
Die oorhoofse doelwit van hierdie projek was dus om ân breĂ« ondersoek na die huidige
wynverbruikersprofiel te doen. Hierdie studie het ân paar doelwitte gehad; eerstens om
fokusgroepe te gebruik om ân beter begrip van Suid-Afrikaanse wynverbruikers van verskillende
etniese agtergronde (Swart, Afrikaner en Kaukasiër, Wit) te kry, met spesifieke fokus op
persepsies, stylvoorkeure, konteks waarin wyn gebruik word, aankoop- en verbruikerspatrone,
sowel as die persoonlike reis na wynverbruik. Die tweede doelwit was om ân vraelys te ontwikkel
wat gebruik kan word om motiverings vir wynverbruik op ân groter skaal te ondersoek. Die derde
doelwit was om verbruikers, opgeleide wynevalueerders en industriekenners se persepsies van
wyn te vergelyk en laastens om die invloed van âwynkultivarâ op verbruikers se sensoriese
persepsies en hedoniese ervaring van wyn te ondersoek.
Die resultate van die fokusgroepe het getoon dat die oorheersende verskille voorgekom het
tussen manlike en vroulike verbruikers. Hierdie studie het nie groot verskille tussen die
verskillende etniese groepe wat ondersoek is, se wynverbruikersprofiele getoon nie.
Oor die algemeen het die wynkeusevraelys getoon dat motiverings vir wynverbruik tussen die
verskillende verbruikersgroepe eenders was. Die sosiale en sensoriese aanvaarbaarheid en
kommer rondom etiese aspekte was die drie belangrikste motiveringsfaktore vir Suid-Afrikaanse
wynverbruikers.
Vir die derde doelwit, naamlik die vergelyking van verskillende groepe se sensoriese persepsies
en hedoniese ervaring van verskillende kultivarwyne, is daar gevind dat die industriekenners,
opgeleide wynevalueerders en verbruikers soortgelyke antwoorde gegee het en dat die
onderskeie groepe op dieselfde wyse tussen die stel steekproefwyne onderskei het. Verbruikers
wat deelgeneem het aan hierdie studie het hulself meestal beskryf as beginners in wynverbruik
en net ietwat kundig oor wyn. Om bewus te wees van die kultivarnaam (ingeligte proe) het nie
die manier waarop verbruikers die wyne beskryf het, asook die hedoniese aanvaarbaarheid van
die wyne noemenswaardig verander nie. Oor die algemeen is al die wyne positief ervaar, selfs
al was elke wyn in ân verskillende kultivarstyl geproduseer.
Hierdie is die eerste studie wat gestrewe het om die veranderende Suid-Afrikaanse
wynverbruikersprofiel beter te verstaan. Die kennis wat opgedoen is het ân aanmerklike bydrae
gelewer tot die begrip rondom Suid-Afrikaanse verbruikers se persepsies van wyn en
beklemtoon ook die rigting wat toekomstige verwante studies kan neem
An exploratory study of urban South African consumersâ perceptions of wine and wine consumption: focus on social, emotional, and functional factors
International audienceWine is of great economic and cultural significance for South Africa, but some population groups were until relatively recently denied equal access to wine and alcohol products. The South African wine industry has launched various campaigns in recent years that aimed at portraying wine as an acceptable and attractive choice when alcohol consumption is considered. It is therefore appropriate now to investigate whether these endeavors of the South African wine industry have resulted in particular consumer behavior and preferences that could serve as input to enhance strategies when marketing to South African consumers. This study uses the thematic analysis method to identify themes that could be of value for wine marketers. To collect data for the study, a total of 44 consumers were assigned to 6 focus groups. Eight main themes driving consumer choices emerged from the data: journey and role of life-stage, context of consumption, conceptualizations, barriers, price and purchasing, bottle closures, health, sensory perception, and cultivars. The influences of gender and ethnicity on consumersâ perceptions of wine and wine consumption were investigated. Gender produced the biggest differences in respect of respondentsâ perceptions about wine and wine consumption whilst ethnicity did not appear to be of any significance
International eDelphi Study to Reach Consensus on the Methotrexate Dosing Regimen in Patients With Psoriasis
Abstract
Importance: A clear dosing regimen for methotrexate in psoriasis is lacking, and this might lead to a suboptimal treatment. Because methotrexate is affordable and globally available, a uniform dosing regimen could potentially optimize the treatment of patients with psoriasis worldwide.
Objective: To reach international consensus among psoriasis experts on a uniform dosing regimen for treatment with methotrexate in adult and pediatric patients with psoriasis and identify potential future research topics.
Design, setting, and participants: Between September 2020 and March 2021, a survey study with a modified eDelphi procedure that was developed and distributed by the Amsterdam University Medical Center and completed by 180 participants worldwide (55 [30.6%] resided in non-Western countries) was conducted in 3 rounds. The proposals on which no consensus was reached were discussed in a conference meeting (June 2021). Participants voted on 21 proposals with a 9-point scale (1-3 disagree, 4-6 neither agree nor disagree, 7-9 agree) and were recruited through the Skin Inflammation and Psoriasis International Network and European Academy of Dermatology and Venereology in June 2020. Apart from being a dermatologist/dermatology resident, there were no specific criteria for participation in the survey. The participants worked mainly at a university hospital (97 [53.9%]) and were experienced in treating patients with psoriasis with methotrexate (163 [91.6%] had more than 10 years of experience).
Main outcomes and measures: In a survey with eDelphi procedure, we tried to reach consensus on 21 proposals. Consensus was defined as less than 15% voting disagree (1-3). For the consensus meeting, consensus was defined as less than 30% voting disagree.
Results: Of 251 participants, 180 (71.7%) completed all 3 survey rounds, and 58 participants (23.1%) joined the conference meeting. Consensus was achieved on 11 proposals in round 1, 3 proposals in round 2, and 2 proposals in round 3. In the consensus meeting, consensus was achieved on 4 proposals. More research is needed, especially for the proposals on folic acid and the dosing of methotrexate for treating subpopulations such as children and vulnerable patients.
Conclusions and relevance: In this eDelphi consensus study, consensus was reached on 20 of 21 proposals involving methotrexate dosing in patients with psoriasis. This consensus may potentially be used to harmonize the treatment with methotrexate in patients with psoriasis
