Exploring the Latest Trends in Hop Usage
What’s changed in how brewers use hops: lupulin powders, extracts, thiol-boosting yeast, new varieties and hop water.
In this post
The short answer: the biggest changes in hop use are concentrated hop products and a better understanding of how yeast unlock hop aroma. Lupulin powders give more aroma with less plant matter and less beer loss. Hop extracts add bitterness or aroma cleanly, and thiol-boosting yeast releases tropical and grapefruit aromas from malt and hops. New varieties keep arriving, and hop water brings hop aroma to a non-alcoholic drink.
| Trend | What it does | Tip |
|---|---|---|
| Lupulin powder | Concentrated hop oils without most of the leaf | Use about half the weight of pellets |
| Hop extracts | CO₂ extract bitters cleanly in the boil; oil-based extracts add aroma without plant matter | Far less trub and wort loss |
| Thiol-boosting yeast | Releases tropical, grapefruit thiols | Pair with hops and malts rich in thiol precursors |
| New varieties | New fruit and dank profiles | Try single-hop pale ales to learn them |
| Hop water | Hop aroma in sparkling water | Keep it cold and drink fresh |
Hop products compared
| Product | What it is | Use it for |
|---|---|---|
| Whole cones | Dried hop flowers | Traditional ales; bulky, and they soak up the most wort and beer |
| T90 pellets | Whole hops milled and pressed; about 90 kg of pellets from 100 kg of hops | Everything. The standard homebrew hop. |
| T45 pellets | Enriched pellets: part of the leaf is sieved out cold, leaving about 45 kg from 100 kg | More lupulin per gram, less plant matter; go by the alpha acid on the pack |
| Lupulin powder (Cryo, LupuLN2) | Lupulin glands separated from the leaf at very low temperature | Whirlpool and dry hop; about half the weight of T90 pellets |
| CO₂ extract | Hop resin (alpha acids and oils) extracted with CO₂ | Bittering in the boil, with almost no trub |
| Isomerised and reduced extracts | Bitterness that’s already isomerised, added to finished beer; reduced forms resist skunking | Adjusting bitterness after fermentation; beer in clear bottles |
| Hop oils and aroma extracts | Concentrated hop oils | Tiny doses in the whirlpool or finished beer; follow the supplier’s rate |
For most homebrewers, T90 pellets plus lupulin powder for big dry hops covers it. Less leaf means less beer lost in the hop sludge and less grassiness.
Where the hops go now
Hop-forward beers have moved most of their hops out of the 60-minute addition and into the whirlpool and dry hop. A typical whirlpool cools the wort to 170–180°F (77–82°C) and steeps a big charge for 20 to 30 minutes: plenty of flavour, little bitterness. Many brewers bitter with CO₂ extract or a small charge of a clean, high-alpha hop so the kettle holds less plant matter. For the details, see bitterness vs hoppiness and our dry hopping guide.
Biotransformation
When hops meet actively fermenting yeast, the yeast change some of the hop compounds. The best-known example: ale yeast turn geraniol (rose-like) into citronellol (citrus). Yeast enzymes can also free aroma compounds that hops hold in an odourless, bound form. That’s why a dry hop at high krausen, or whirlpool hops that go into the fermenter with the wort, can taste fruitier than the same hops added after fermentation. Results depend heavily on the yeast strain, so split a batch and taste before you rely on it.
Thiols
Thiols are sulphur-containing aroma compounds that you can smell at incredibly low levels. They’re the same compounds that give Sauvignon Blanc its grapefruit and passionfruit character.
| Thiol | Smells like |
|---|---|
| 4MMP | Blackcurrant; catty when overdone |
| 3MH | Grapefruit, passionfruit |
| 3MHA | Passionfruit, guava |
Most of the thiol potential in wort is locked up in odourless precursors from malt and hops. Ordinary ale yeast free only a small part of it. Thiol-boosting strains, some of them genetically engineered, free much more and can give big tropical aroma with modest hopping. The precursors survive the boil, so kettle and whirlpool hops feed them too.
Newer hop varieties
Cascade, released in the early 1970s, started the American citrus-hop style. The varieties since then lean harder into fruit:
| Hop | From | Aroma |
|---|---|---|
| Citra | US | Grapefruit, lime, tropical fruit |
| Mosaic | US | Blueberry, tropical fruit, pine |
| Simcoe | US | Pine, passionfruit, citrus |
| Sabro | US | Tangerine, coconut |
| Galaxy | Australia | Passionfruit, peach |
| Nelson Sauvin | New Zealand | White wine grape, gooseberry |
| Motueka | New Zealand | Lime, lemon |
The best way to learn a new hop is a single-hop pale ale: same malt, same yeast, one hop. Buy the latest harvest, check the oil content (mL per 100 g) on the spec sheet, and keep hops vacuum-sealed in the freezer. Our American pale ale recipe makes a good base.
Frequently asked questions
What’s the difference between T90 and T45 pellets?
T90 pellets are the whole hop, milled and pressed. T45 pellets have part of the leaf removed, so each gram carries more lupulin and less plant matter.
Is lupulin powder worth it for homebrewers?
For big dry hops, yes: you lose less beer to hop sludge and get less grassiness. For small additions, pellets are fine.
Do I need thiol yeast for a tropical IPA?
No. Fruity hops like Citra, Galaxy and Nelson Sauvin get you there with a normal ale yeast. Thiol yeast turns it up further.
What is hop water?
Sparkling water flavoured with hops: no malt, no alcohol. The hop aroma fades fast, so keep it cold and drink it fresh.
