# Saison
Saison is a highly attenuated, dry, hoppy Belgian farmhouse ale that originated in Wallonia, the French-speaking southern part of Belgium, and is defined above all by its yeast-driven fermentation character: fruity esters, peppery phenols, very high carbonation, and a bone-dry finish. The name is French for "season," and at the beginning of the 20th century it referred to when the beer was consumed: brewed in winter, refermented for months in wooden barrels, and served in summer to quench the thirst of seasonal farm workers, the *saisonniers*.[1](https://www.brasserie-dupont.com/en/)
| Key fact | Detail |
|---|---|
| Origin | Farmhouse breweries in Wallonia, Belgium, primarily the province of Hainaut; related farmhouse traditions existed across northern France and elsewhere in Europe[2](https://www.beerandbrewing.com/dictionary/UzfCHVbjtk) • [3](https://beer-styles.ebcu.org/saisons/) |
| Vital statistics (BJCP) | OG 1.048–1.065; FG 1.002–1.012; ABV 5–7% (standard); IBU 20–35; SRM 5–14[4](https://www.bjcp.org/beer-styles/16c-saison/) |
| Attenuation | Extreme attenuation of 85–95% produces the characteristic very dry finish[4](https://www.bjcp.org/beer-styles/16c-saison/) |
| Fermentation profile | Fruity esters (citrus, pome, stone fruit), peppery rather than clove-like phenols, no diacetyl, and somewhat higher acidity than other Belgian styles[4](https://www.bjcp.org/beer-styles/16c-saison/) |
| Strength variants | Table beers about 5% ABV, typical export beers about 6.5%, and stronger versions of 8%+[4](https://www.bjcp.org/beer-styles/16c-saison/) |
| Benchmark beer | Saison Dupont, first produced in the 1920s, is the best-known modern example and the brewery's number one export[4](https://www.bjcp.org/beer-styles/16c-saison/) • [1](https://www.brasserie-dupont.com/en/) |
| Modern categories | The Brewers Association separates Classic French & Belgian-Style Saison from Specialty Saison; the BJCP classifies saison as 25B within Belgian ales[5](https://www.brewersassociation.org/edu/brewers-association-beer-style-guidelines/) • [6](https://www.bjcp.org/style/2021/25/25B/saison/) |
## History
Saison began as a provision beer of Walloon farm breweries. Farm brewers spent the cooler months building a stock of beer to drink through the year, particularly the summer season, when heat made brewing risky and thirst in the fields was high.[2](https://www.beerandbrewing.com/dictionary/UzfCHVbjtk) The beer had to be sturdy enough to last for months but not so strong that field workers could not keep working after drinking it; originally it was a lower-alcohol product, though tavern-strength versions also existed.[4](https://www.bjcp.org/beer-styles/16c-saison/) Hops were used generously in part because their antibacterial properties helped prevent infection during long storage.[7](https://midchilterns.camra.org.uk/wp-content/uploads/2025/09/tapler-winter-2024-final-v3.pdf)
The style survived the 20th century in various forms in southern Belgium and parts of eastern France.[3](https://beer-styles.ebcu.org/saisons/) The beer's recorded past reaches further back and over a wider area than the Hainaut account by itself implies: references to saison in Liège date to no later than 1832, whereas the earliest written record of brewing it in Hainaut dates to 1858.[8](https://twirl.github.io/Beer-Lecture/Sergey%20Konstantinov.%20Beer%20-%20a%20Lecture%20%28Tasting%20Included%29.en.pdf) Historians also caution that the familiar tale of saison as a fixed low-strength daily ration of several liters a day for farmhands is repeated widely but thinly sourced.[9](https://beerhq.app/styles/saison)
Higher-strength and differently colored versions appeared after World War II. The best-known modern saison, Saison Dupont, was first produced in the 1920s; Dupont's super saison followed in 1954 and its brown version in the mid-1980s, and Brasserie Fantôme began producing its seasonal saisons in 1988.[4](https://www.bjcp.org/beer-styles/16c-saison/) The Dupont brewery traces its roots to a farm in Hainaut established in 1759 that became a farm-brewery in 1844, producing honey beers and saison for agricultural workers; Louis Dupont revived the saison recipe in 1920, and the beer is now brewed year-round.[1](https://www.brasserie-dupont.com/en/) • [10](https://www.brasserie-dupont.com/notre-histoire/)
## Sensory character
The BJCP describes the family as refreshing, highly attenuated, hoppy, and fairly bitter Belgian ales with a very dry finish and high carbonation, typically pale gold to deep amber with a long-lasting, dense, rocky white head.[6](https://www.bjcp.org/style/2021/25/25B/saison/) Aroma and flavor are dominated by the yeast: moderate to high fruity esters often reminiscent of citrus, pome, or stone fruit, with spicy notes more like black pepper than clove, over a light grainy malt base and continental hops that are spicy, floral, earthy, or fruity.[6](https://www.bjcp.org/style/2021/25/25B/saison/) A bone-dry finish and a lingering, bitter, occasionally peppery aftertaste come from the high carbonation, water moderately rich in sulfates, and extremely high attenuation; the bitterness a drinker perceives frequently exceeds what the IBU figure would imply.[4](https://www.bjcp.org/beer-styles/16c-saison/) Saisons share somewhat higher acidity than other Belgian styles, and a low to moderate tartness may be present without puckering.[4](https://www.bjcp.org/beer-styles/16c-saison/)
**Ingredients.** Pilsner malt dominates the grist, with portions of Vienna or Munich malt for color and complexity, and sometimes other grains such as wheat, oats, spelt, or rye; sugar or honey adjuncts thin the body and add complexity.[4](https://www.bjcp.org/beer-styles/16c-saison/) Noble hops, Styrian Goldings, or East Kent Goldings are commonly used, and the beer is sometimes dry-hopped.[4](https://www.bjcp.org/beer-styles/16c-saison/) Yvan De Baets, co-owner and brewmaster of [Brasserie](https://www.edgepedia.org/brasserie) de la Senne in Brussels, has named spelt as his favorite specialty grain for the style, for the fresh cereal character, body, and foam it contributes.[11](https://www.brewersassociation.org/insights/style-spotlight-saison/)
## Yeast and fermentation
The style is defined by its yeast. Saison strains of *Saccharomyces cerevisiae* prefer high fermentation temperatures, sometimes finishing well above 27 °C (80 °F), which would produce off-flavors in most other ale yeasts, and they are extraordinarily attenuative, consuming sugars other yeasts leave behind.[12](https://nationalbeerauthority.com/belgian-saison-and-farmhouse-ales/) Many saison strains carry the STA1 gene of *S. cerevisiae* var. diastaticus, which encodes glucoamylase and lets the yeast ferment dextrins that ordinary brewing yeasts cannot; this drives attenuation toward 90% but also means the beer can keep fermenting in the bottle for months, risking over-carbonation if not fully attenuated before packaging.[13](https://www.brewsbase.com/blog/saison-brewing-guide/) The same diastatic property makes these strains a contamination hazard in breweries packaging other beers.[14](https://journals.asm.org/doi/10.1128/aem.01072-24)
Brettanomyces occupies an ambiguous place in the style. The [Brewers Association](https://www.edgepedia.org/brewers-association) allows that in more traditional versions, Brettanomyces-derived attributes, slightly acidic, fruity, horsey, goaty, or leather-like, may be present.[5](https://www.brewersassociation.org/edu/brewers-association-beer-style-guidelines/) De Baets goes further, saying that if there has been one "saison" yeast, it is [Brettanomyces](https://www.edgepedia.org/brettanomyces), and that a noticeable vinous Brett character in balance with noble hops and malt belongs in the style.[11](https://www.brewersassociation.org/insights/style-spotlight-saison/) The BJCP takes the opposite position for competition: Brettanomyces is not typical for the style, and saisons with Brett should be entered as Brett Beer.[6](https://www.bjcp.org/style/2021/25/25B/saison/)
## Style categories and comparisons
The Brewers Association guidelines split the style in two. Classic French & Belgian-Style Saison covers straw-to-amber beers of 4.50–6.50% ABV, original gravity 1.040–1.060, 20–38 IBU, and color 2–15 SRM, well attenuated, refreshing, and well balanced, with medium to high hop aroma from traditional European-type hops and medium to medium-high fruity esters.[5](https://www.brewersassociation.org/edu/brewers-association-beer-style-guidelines/) Specialty Saison is a deliberately wide family for versions deviating substantially through dark malts, fruit, spices, herbs, wood-aging, or other ingredients, with a permitted range up to 9.30% ABV and 40 IBU.[5](https://www.brewersassociation.org/edu/brewers-association-beer-style-guidelines/)
The BJCP recognizes strength and color variants: table, standard, and super strengths (3.5–5.0%, 5.0–7.0%, and 7.0–9.5% ABV respectively) and pale or dark colors, with sweetness decreasing and spice, hop, and sour character increasing with strength.[6](https://www.bjcp.org/style/2021/25/25B/saison/) Its closest relative is often said to be Bière de Garde, brewed in northern France, but the BJCP draws a sharp line: Bière de Garde is malty and smooth, while saison is hoppy and bitter.[15](https://www.bjcp.org/download/2021-bjcp-beer-style-guidelines-change-log) In the United States the term "farmhouse ale" is often used interchangeably with saison, though in Europe the term is not common and saison is simply part of a larger grouping of artisanal ales.[6](https://www.bjcp.org/style/2021/25/25B/saison/)
## Modern brewing and judging
Saison is now brewed year-round, mostly in larger breweries, though it retains its rustic farmhouse image.[4](https://www.bjcp.org/beer-styles/16c-saison/) Judges and brewers emphasize balance as the style's hardest requirement. De Baets, who judged the category at the 2026 World Beer Cup, lists the common faults: "phenolic bombs" in which medicinal phenols overwhelm the beer, one-dimensional ester-heavy versions resembling Belgian blond, underattenuated beers with residual sweetness, excessive spicing, and beers that are simply too strong, since perceptible alcohol signals a problem.[11](https://www.brewersassociation.org/insights/style-spotlight-saison/) His summary of the target: "extremely drinkable, simple and complex at the same time."[11](https://www.brewersassociation.org/insights/style-spotlight-saison/)
Commercial examples cited by the BJCP include Saison Dupont Vieille Provision, Fantôme Saison D'Erezée – Printemps, Saison de Pipaix, Saison Regal, Saison Voisin, Lefebvre Saison 1900, Ellezelloise Saison 2000, Boulevard Tank 7 Farmhouse Ale, and Ommegang Hennepin.[4](https://www.bjcp.org/beer-styles/16c-saison/)
