ISG Sommelier study plan

ISG Sommelier · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Wine, viticulture and enology

  • Map the Domain 1 syllabus into a one-page outline covering viticulture, vinification, maturation, and bottling, then rank each subtopic by exam weight

  • Explain the annual vine growth cycle and name the main grape varieties of France, Italy, Spain, Germany, and the New World by region

  • Describe still white, red, and rosé vinification step by step, including temperature control, maceration length, and press fractions

  • Define the key enology terms (must, lees, malolactic fermentation, chaptalization, dosage, sulfur dioxide) in your own words

Your checkpoint

A one-page Domain 1 concept map plus a 60-term glossary written from memory, reviewed against notes

Week 2

Wine, viticulture and enology

  • Distinguish the major sparkling methods (traditional, tank, transfer, ancestral) by process and label terms

  • Trace fortified and sweet wine production (Port, Sherry, Madeira, late harvest, icewine, botrytis) and the styles each method produces

  • Compare oak maturation variables (species, toast level, barrel size, age) and their sensory outcomes

  • Identify the main faults and their causes (oxidation, reduction, cork taint, volatile acidity, Brettanomyces) and the corrective or preventive practice

Your checkpoint

A 40-question self-written quiz on production methods and faults, scored with an explanation for every wrong answer

Week 3

Sensory analysis and sommelier practice

  • Build a structured tasting template covering appearance, nose, palate, and conclusion, and use it on six wines

  • Practice the systematic approach to tasting aloud, timing yourself to a concise two-minute presentation per wine

  • Calibrate your palate on the principal aroma families (fruit, floral, herbal, spice, oak, earth, faults) using reference standards or guided flights

  • Explain the physiology of smell and taste and how it affects perception, adaptation, and threshold

Your checkpoint

Six completed tasting notes in the standard format, each with a written quality and readiness-for-drinking conclusion

Week 4

Sensory analysis and sommelier practice

  • Define the deductive tasting method and apply it blind to identify grape variety, origin, and style with stated reasoning

  • Describe the service temperature, decanting, and glassware decisions that follow from a tasting conclusion

  • Explain the sommelier's role in menu pairing: weight, acidity, tannin, sweetness, and umami interactions

  • Identify the professional bodies, certifications, and codes of conduct relevant to sommelier practice

Your checkpoint

A blind tasting of four wines with written deductions, plus a 300-word pairing rationale for a three-course menu

Week 5

Hospitality and beverage service

  • Sequence the steps of professional wine service from greeting to glass, including opening, decanting, and pouring

  • Describe cellar and inventory management: stock rotation, temperature and humidity control, and bin organization

  • Explain responsible-service obligations, age-verification, and how to handle a guest who appears intoxicated

  • Outline the roles and workflow of a beverage team during a busy service and how to brief staff before service

Your checkpoint

A written service standard operating procedure for wine service plus a 10-minute role-play demonstration of decanting and pouring

Week 6

Global beverage business and management

  • Calculate pour cost, cost of goods sold, and contribution margin for a by-the-glass list and identify the levers that improve margin

  • Explain how pricing, menu engineering, and wine-list structure influence sales mix and revenue

  • Describe purchasing and supplier relationships, including allocation, negotiation, and import logistics basics

  • Identify the main distribution models (three-tier, direct, on-premise vs retail) and how they affect price and availability

Your checkpoint

A one-page by-the-glass profitability model with pour cost, margin, and a recommended price for five wines

Week 7

Nutrition and applied sciences & Trade, regulation, culture and international markets

  • Summarize the nutritional composition of wine and beer (alcohol, calories, sugar, sulfites) and the health guidance around consumption

  • Explain the role of sulfites, additives, and allergen labeling in wine and how to answer guest questions accurately

  • Describe the main trade agreements, appellation systems, and labeling rules that govern wine sold internationally

  • Compare the cultural role of wine in at least three producing countries and how it shapes service expectations

Your checkpoint

A two-page briefing note covering nutrition facts, labeling rules, and cultural service differences for three markets

Week 8

Wine, viticulture and enology & Sensory analysis and sommelier practice & Hospitality and beverage service & Global beverage business and management & Nutrition and applied sciences & Trade, regulation, culture and international markets

  • Revisit the weakest three subtopics from each domain and rewrite them from memory

  • Complete two full-length timed mock exams under exam conditions and analyze every error by domain

  • Deliver a final blind tasting and a five-minute spoken presentation on a wine region, both under time pressure

  • Consolidate a one-page summary sheet of formulas, service steps, and key terms for final review

Your checkpoint

Two scored mock exams with an error log, plus a one-page final summary sheet

Milestones

Week 2: Score at least 80% on your self-written production and faults quiz, with every error corrected in writing

Week 4: Complete a blind tasting of four wines with correct variety or origin called on at least three, and a passing-quality written deduction for each

Week 6: Produce a by-the-glass model in which pour cost is within a defensible target range and you can explain each pricing lever without notes

Week 8: Score at least 80% on both timed mock exams and show a written error log covering all six domains
