Hoparoma - IPA Hop Recipes

Brew in your own units: hops in oz, malt in lb, temperature in °F, batch in gallons for US/UK/CA/AU/NZ, metric everywhere else. Plus BeerXML import.

To our knowledge, Hoparoma is the first iOS app to predict tropical thiol — the science behind every juicy, modern IPA — across yeast, hop, malt, and Phantasm.

Most brewing apps tell you what hops to use. Hoparoma predicts what your beer will smell like, before you brew it. The Thiol Forecast Bento card shows how your yeast, hops, malt, and Phantasm dose combine to produce tropical aroma in a single, science-honest forecast.

Designed for both homebrewers and craft brewers.

New in 1.0.5: BeerXML import + lot-level crop year hop data + imperial units.

—— FEATURES ——

THIOL FORECAST BENTO CARD A 3+1 layout score on every recipe. See exactly how Yeast × Hop × Malt combine to release tropical thiol, plus how a Phantasm dose amplifies the result. Barley malt holds up to 700 µg/kg of bound 3MH precursor, hops carry free and bound thiols, and yeast's β-lyase enzyme is the gate that unlocks them all.

EXPANDED YEAST LIBRARY (23 STRAINS) Includes Cosmic Punch, Helio Gazer, Star Party, LalBrew New England, WLP077 Tropicale, Lutra Kveik, Hornindal Kveik, A04 Barbarian (Conan), Belle Saison, WLP029 Kölsch — each rated for thiol biotransformation activity. Availability badges (Mainstream / Limited / Pro Pitch Only) tell you what you can actually source.

EXPANDED MALT LIBRARY (41 ENTRIES) Includes Naked Oat Malt, the full CaraMunich series, Melanoidin, Abbey, Carafa, and Aromatic — each rated for thiol precursor level (high / medium / low / negligible).

IMPORT FROM BREWFATHER & BEERSMITH (PRO) Bring recipes you have already dialed in into Hoparoma. BeerXML import reads standard .beerxml / .xml files from Brewfather, BeerSmith, and other tools, then maps your hops, yeast, and malts to Hoparoma's chemistry model so you get a Thiol Forecast on every imported recipe.

MINDFUL RECIPE PRESETS Mindful Hazy Session IPA (4.2% ABV) and Sober-Curious Session Pale (3.8% ABV) — designed with the Thiol Forecast in mind, so low-ABV beers don't sacrifice tropical aroma. Plus 5 classic hop-forward presets sourced from public clones (Vinnie Cilurzo, Hawkers, Trillium).

—— WHY HOPAROMA ——

Brewfather optimizes recipe management. BeerSmith offers hop-side thiol awareness through its web Hop Control tool. To our knowledge, Hoparoma is the first iOS app to predict the full 4-axis Thiol Forecast — yeast × hop × malt × Phantasm — in a single integrated engine.

The difference: we model thiol biotransformation across every layer, not just hops. Yeast β-lyase, malt precursors, hop thiols, and Phantasm dose are combined in real time as you build your recipe.

For homebrewers chasing the perfect Hazy IPA, craft brewers dialing in tropical character without doubling dry hops, and anyone trading guesswork for chemistry.
