Style Review: What is it?A Belgian Dark Strong Ale is Belgian, so its complex and interesting Dark, so its not pale Strong, so its bigger than a dubbel Ale, so its not Stella The Belgian Dark Strong Ale STYLE is An artificial American judging construct not an authentic Belgian brewing constraint A catch-all category for large, dark Belgian beers that fall within Category S (a legal classification, OG 1.062+) Jackson and Protz: not defined as a style (contained within Trappist, Monastic Beers and Regional Specialties)

Style Review: Sensory AspectsFactor Appearance Aroma Typical Qualities of Best Examples Light coppery-red to deep coppery-brown. Huge, dense, moussy, persistent head. Can be clear or somewhat hazy Complex; rich malty sweetness, estery, alcohol, spiciness Malt: rich, some Munich, occasional caramel, toast, bread Fruity esters: raisin, plum, dried cherry, fig, prune Spicy phenols (light notes of pepper, not clove) Alcohol (soft, spicy, perfumy, rose-like) Similar to aroma, plus: Moderately Malty or sweet, but finishes dry Low bitterness; alcohol balances malt High carbonation but no bite Smooth alcohol warmth Variable body by interpretation (med-light to full) Complex, rich, smooth, dangerous

Brewing: IngredientsBased on results of homebrewer survey Authentic ingredients tend to produce authentic results
Aspect CommentsWater Hops Soft is best (dont need sulfates or carbonates). Try RO + CaCl2. Low bitterness (15-25 IBUs), try BU:GU of about .33 Balance depends on not having excessive residual sweetness Low to no late hops (less than .5 oz per 5 gal), noble if used Complexity comes from variety. Belgian Pale or Pils base. Malt Munich-types for maltiness, Belgian specialties for flavor Avoid US/UK crystal-types (wrong type of sweetness) Adjuncts Sugar is needed to lighten body, add color/complexity Candi sugar is best, others work. Avoid molasses flavors. Start with 5-10% up to a maximum of 20% of grist Authentic Belgian types required for proper character Yeast Lots of healthy yeast, plenty of oxygen Ferment warm (70 2), depending on strain Avoid if possible. If using, be subtle and keep in background. Spices Try complimentary spices (star anise, cardamom, black pepper)
Brewing: Yeast Selection Check out Crispy Freys talk on Belgian yeasts Favorite examples from brewers: Rochefort-type: WY1762, WLP550 (can need attention to fully ferment) Chimay-type: WY1214, WLP500 (keep cool to avoid high esters and solvents, good attenuator) Westmalle-type: WY3787, WLP530 (lots of phenols, use temperature to control ester profile, good attenuator) Achouffe-type: WY3522 (can ferment very warm)
Consider a bottling yeast if you bottle-condition (Chico is fine) Consider using multiple strains for added complexity Experiment with warmer fermentations in shallow fermenters Fermentation management is critical to the final product
Brewing: Malt SelectionMaltMunich Aromatic CaraMunich CaraVienne
Benefit or Resulting CharacteristicRich malty flavor/aroma. Dont use as base (youre not making a bock). Also can use Vienna. Like super Munich. Also Melanoidin. Nutty, malty. Plum and dried cherry flavors. Darker color. Sweetness, light caramel/malty flavors.
Biscuit/Victory Toasty, bready. Background flavor only (not an ESB). Special B Chocolate Wheat Raisin flavors. Can be grainy and overpowering. Use sparingly for color adjustment. Consider light or huskless varieties to avoid roasted flavors. Use for added head retention and flavor complexity.
Brewing: Process Mash for Attenuation Specialty grains will provide body Consider step mashing, particularly if using pils malt Convert at lower end of beta amylase range (149-150)
Practice Good Yeast Management Pitch a big, healthy starter and use lots of oxygen Consider adding sugar adjuncts after fermentation is going Keep it going, but dont let it overheat
Conditioning for the Long Term Avoid post-fermentation oxygen pickup Good sanitation and packaging techniques Consider bottle conditioning with a new, healthy strain Be Patient. Wait 3-6 months before tasting. Peak in 9-24 months.

Common Judging Errors Not understanding the full range of the style Big Beer bias Halo effect of favorite commercial beer
Dismissing spiced and paler versions Misunderstanding style guidelines Phenolic doesnt mean weizen-like
Not deducting for faults (or detecting them) Misunderstanding body, sweetness, attenuation, carbonation and alcohol strength Liking fusels and other off-flavors
Common Brewing Errors (1) Fermentation Management Temp too high (fusels, solvents) Poor yeast health (inadequate pitching) Too high FG (infection-prone, syrupy, cloying) Not clean enough (infected, sour, phenolic, medicinal) Wrong yeast (insufficiently Belgian) Unbalanced Too much spicing Roasted, burnt flavors Lacking complexity in malt profile and yeast character
Common Brewing Errors (2) Lack of Style Fidelity Just because its big, dark and (possibly) funky, doesnt mean its a good match for the style Alcohol cant mask other problems Too bitter, hoppy, roasted, or sweet. Too much body. Too pale in color.
Lack of Aging Rough flavors (grains, fusels, alcohol hotness) Unpleasant balanced; flavors not melded High residual sweetness (needs to dry out, firm up)
Recommendations: Style Changes Tighten definition to traditional Trappist/Abbey styles Minimize overlap with Dubbel Raise gravity range: OG 1.075-1.110 Allow for drier beers: FG 1.010-1.024 Decrease IBUs: 15-25 (higher is OK if FG is also high) Color is too light: 14-20 SRM Raise ABV slight: 8-12% Allow for lighter bodied, drier versions De-emphasize spicy phenols Emphasize dark, dried fruit flavors and aromas Discuss variations, balance, smoothness, malt complexity Head should be moussy and long-lasting
Recommendations: Brewing Tips Focus on making classic Trappist styles, not Barleywinetypes and spiced variations. Judges expect Belgian character and complexity from malt, yeast and sugar. Use a variety of grains. Use sugars to cut the body and increase alcohol and flavor. Adjust color with very small amounts of darker malts; judges dont like this style to be too pale. Avoid overhopping. Let the alcohol balance the malt. But it needs to attenuate for this to occur (age it). Dont enter your beers too young. If theyre well made, they can wait until next year. Fermentation management is probably the most critical factor in determining the quality of the final product.
