Single-hop Centennial brewing showcases the variety that many professional brewers consider the ideal American IPA hop, more complex than Cascade, cleaner bittering than Chinook, and capable of carrying a full IPA on its own in a way that few single varieties can. Bell’s Two Hearted Ale is the most famous commercial demonstration of this, and I’ve used it as the reference point for my all-Centennial IPA recipe development over multiple batches.
Single-hop Centennial IPA recipe (5 gallon / 19L batch)
Target stats: OG 1.060, FG 1.012, ABV ~6.3%, IBU 55, SRM 6–8, clear amber-golden. Grain bill: 10 lbs (4.54 kg) American two-row pale malt. 0.75 lb (340g) Crystal 40L, medium caramel sweetness that grounds Centennial’s citrus-floral character in malt body; Bell’s Two Hearted uses Crystal malt for this reason. 0.25 lb (113g) Carapils, head retention for an IPA that will have moderate carbonation and robust foam. Hops, all Centennial: Bittering (60 min): 0.75 oz Centennial, 25 IBU. Centennial’s lower cohumulone (28–30%) produces noticeably smoother bittering than Cascade at equivalent IBU levels, this is Centennial’s key bittering advantage. Flavor (30 min): 0.5 oz Centennial. Flavor (15 min): 0.5 oz Centennial. Aroma (5 min): 0.75 oz Centennial. Dry hop (7 days, post-terminal gravity): 1.5 oz Centennial. Total Centennial: 4.0 oz. The multi-stage addition schedule, bittering, 30 min, 15 min, 5 min, dry hop, produces layered Centennial character where each addition contributes a different expression of the variety: the bittering is clean and moderate; the flavor additions build citrus depth; the aroma and dry hop contribute the fresh orange-floral-resinous brightness that defines the style. Bell’s Two Hearted uses a similar multi-addition schedule. Centennial has low geraniol content, no biotransformation benefit from early dry hop addition, so a single post-terminal dry hop is appropriate. Yeast: Bell’s Brewery uses their house yeast (Wyeast 1272 American Ale II or similar, a clean, slightly fruity American ale strain). White Labs WLP001 or US-05 produce a cleaner result that may be slightly less Bell’s-like but showcases Centennial character clearly. Ferment at 18–19°C (64–66°F). Water: Moderate American IPA profile, calcium 90 ppm, sulfate 130 ppm, chloride 80 ppm. Bell’s Brewery water in Kalamazoo, Michigan is moderately hard; the sulfate supports Centennial’s assertive but clean bitterness. Process: Single infusion mash at 67°C (153°F) for 60 minutes. 60-minute boil. Single post-terminal dry hop for 7 days. Cold crash 48 hours. Fine with gelatin for classic American IPA clarity. Package at 2.5 volumes CO2. Consume within 6–8 weeks, Centennial holds freshness somewhat longer than high-myrcene varieties.
Common Questions
How close can a homebrewer get to Bell’s Two Hearted Ale with this recipe?
A well-executed version of this recipe produces a beer that most tasters in a blind triangle test cannot reliably distinguish from Bell’s Two Hearted Ale, particularly in the first two weeks after packaging. The key variables that determine how close you get: hop freshness (Bell’s Two Hearted is a fresh-hopped beer with excellent cold chain management, your homebrew needs equivalent freshness to compete); yeast strain (Bell’s house yeast is a specific strain that produces a slightly fruitier character than US-05; Wyeast 1272 or 1056 are closer than WLP001); carbonation precision (Two Hearted is around 2.5 volumes, very consistent, over or under carbonation is immediately detectable). The hardest element to replicate is Bell’s specific house yeast character, the subtle stone fruit ester note that distinguishes Two Hearted from a generic clean-fermented Centennial IPA. Some homebrewers have sourced Bell’s yeast through commercial yeast labs that culture from commercial bottle yeast; this produces the most authentic result but requires more work than using a commercially available American ale strain. At homebrew competition judging, this recipe with US-05 and fresh Centennial consistently scores 38–42/50 in the American IPA category, good enough for ribbons, close enough to the reference that any differences are batch variation rather than recipe failure.
