Understanding Hop Varieties
Held on Friday, June 19, 2026
Smelled like a pine forest in here.What we covered
What a session.
We had sixteen people around the brewhouse table for our deep dive into hops — easily our best turnout yet. Luke kicked things off with the basics: alpha acids, beta acids, and why the same hop can taste completely different depending on when you throw it in the kettle.
The Big Three: Bittering, Flavour, Aroma
The core lesson was simple but powerful: hops added in the first 60 minutes of the boil isomerise their alpha acids and contribute bitterness. Additions in the last 15–20 minutes give you flavour — that bridge between bitter and aromatic. And anything at flameout or during dry-hopping is pure aroma, no bitterness at all. Once you understand that timeline, your hop schedule stops being a recipe you follow and starts being a tool you control.
We passed around six varieties — Cascade, Centennial, Citra, Saaz, East Kent Goldings, and Galaxy — and everyone rubbed the pellets between their palms to release the oils. The room smelled incredible. The contrast between the earthy, spicy Saaz and the tropical punch of Galaxy was the moment you could see the lightbulbs going off.
Hands-On: The Hop Tea Tasting
The highlight was the hop tea comparison. Luke had pre-brewed four hop teas at identical concentrations: Citra (citrus/tropical), Mosaic (berry/earthy), Simcoe (pine/resin), and Hallertau (floral/herbal). Tasting them side-by-side in hot water — no malt, no yeast, no carbonation — strips away everything except the hop character. Several people said this was the first time they could truly isolate what "hoppy" actually means in different contexts.
One attendee brought a homebrew IPA that was getting a harsh, grassy bitterness. We talked through the recipe and figured out the issue: whole-leaf hops left in the fermenter too long during a dry-hop. That turned into a great real-world discussion about dry-hop timing, temperature, and when to pull the bag.
The Tour
We wrapped up with a walk through the Gridiron brewhouse. Luke showed how we use the same principles at production scale — our hop schedule for the Forbidden IPA, the whirlpool additions on T-Shirt Weather, and the dual dry-hop on the seasonal NEIPA. Seeing the 500L fermenter with the dry-hop charge floating on top made the theory click.
Everyone left with a sample baggie of Citra and Mosaic pellets and a one-page hop reference sheet. If you missed this one, the key takeaways below will get you started — and we'll be running a follow-up on yeast in a few months.
Key Takeaways
- Hops added early in the boil contribute bitterness (alpha acid isomerisation); late additions contribute aroma and flavour
- Citra, Mosaic, and Simcoe are versatile American varieties — great starting points for any style
- Dry-hopping adds aroma without bitterness — but leave hops in too long and you get grassy off-flavours
- Store hops sealed and frozen to preserve alpha acids — oxygen and heat are the enemy
- Hop teas (hot water + hops, no malt) are the fastest way to learn what each variety actually tastes like
- Noble hops (Saaz, Hallertau, Tettnanger) are earthy and floral — the backbone of lagers and Belgian styles
About this hangout
Hops are one of the four core ingredients in beer, but most homebrewers only know them by name on a packet. In this hangout we break that open — literally. We'll rub whole-leaf and pellet hops, smell the difference between old-world noble varieties and new-world fruit bombs, and talk about when to add them for bitterness versus aroma.
Whether you're brewing your first extract kit or you're an all-grain veteran looking to refine your hop schedule, you'll walk away with a better nose and a clearer plan for your next brew day.
