Types of Wine — Still, Sparkling, Fortified, and Sweet
Understanding the four main categories of wine and how each is made
Learning Objectives
- Define still, sparkling, fortified, and sweet wine and explain how each is made
- Give at least two examples of each wine type
- Explain how fortified wines differ from still wines in terms of production and alcohol
- Describe the main methods for making sweet wines
Still Wines
Still wines are the most common category — wines without significant carbonation. They range from light, delicate whites (Muscadet, Pinot Grigio) to full-bodied, tannic reds (Barossa Shiraz, Barolo). Still wines are produced by fermenting grape juice until the desired dryness is reached, with alcohol typically between 11% and 15% ABV. Rosé wines fall into this category — they acquire their pink colour from brief skin contact with red grape skins.
Sparkling Wines
Sparkling wines contain dissolved CO₂ that creates bubbles when poured. The carbonation comes from a secondary fermentation — either in the bottle (traditional method, used for Champagne and Cava) or in a sealed tank (tank method, used for most Prosecco). A third method, the transfer method, combines elements of both. The finest sparkling wines develop complex autolytic (yeasty, biscuit, brioche) aromas from extended contact with yeast lees. Key styles include Champagne (France), Cava (Spain), Prosecco (Italy), Crémant (France), and Sekt (Germany).
Fortified Wines
Fortified wines have neutral grape spirit added during or after fermentation, raising alcohol to 15–22% ABV and halting fermentation if added mid-process (preserving residual sugar). Port is fortified during fermentation, leaving unfermented sugar for sweetness. Sherry is typically fortified after fermentation to dryness, then aged under flor (yeast) or oxidatively. Madeira and Marsala are other important fortified styles. The higher alcohol acts as a preservative, allowing these wines to age for decades.
Sweet Wines
Sweet wines retain residual sugar — either by stopping fermentation early, using botrytised (nobly rotted) grapes, drying grapes (passito/appassimento), using frozen grapes (Icewine/Eiswein), or using late-harvest grapes with high natural sugar. Famous sweet wine styles include Sauternes (botrytis, France), Tokaji Aszú (botrytis, Hungary), German Auslese and Trockenbeerenauslese (late harvest and botrytis), Icewine (Canada and Germany), and Recioto della Valpolicella (Italy, dried grapes).
Key Vocabulary
Exam Question Examples
How is Port wine made sweet?
Approach
Port is fortified during fermentation — grape spirit is added while the wine still contains unfermented sugar. The high alcohol (around 77% ABV spirit) kills the yeast, stopping fermentation and leaving the wine sweet. This distinguishes it from Sherry, which is typically fortified after fermentation to dryness.
Quick Summary
- 1.Still wines: no carbonation, 11–15% ABV — most common wine type
- 2.Sparkling wines: CO₂ from secondary fermentation in bottle (traditional) or tank (Charmat)
- 3.Fortified wines: added grape spirit raises alcohol to 15–22% ABV
- 4.Sweet wines: residual sugar from arrested fermentation, botrytis, drying, or freezing grapes
- 5.Key examples: Champagne (sparkling), Port (fortified-sweet), Sauternes (sweet), Sherry (fortified-dry)

Frequently Asked Questions
- Is rosé wine a separate category?
- Rosé is a style of still wine, not a separate category. Most rosé is made by brief skin contact — red grape skins are left in contact with the juice for a short time (hours, not days) to impart colour. It can also be made by blending a small amount of red wine into white wine, which is permitted for Champagne rosé but not for most still rosé.
- What is the difference between dry and sweet wine?
- A dry wine has had virtually all its sugar fermented into alcohol — residual sugar is below about 4g/L, which most palates cannot detect as sweetness. A sweet wine has measurable residual sugar, either because fermentation was stopped early, the grapes had very high natural sugar, or the wine was produced using botrytis, drying, or freezing methods.
