BarthHaas® SPECTRUM – BRU-1® 1kg

Spectrum Bru-1

BRU-1 is an American hop variety known for its intense aromas of freshly sliced pineapple and white fruits. It is especially appreciated in beers such as wheat ales, IPAs, Pale Ales, and NEIPAs.

This hop is an excellent choice for home brewers looking to infuse their recipes with bold pineapple character. Moreover, trials have shown that BRU-1 can improve haze stability in certain beer styles.

It stands out for its exceptionally high beta acid content, helping preserve bitterness and maintain balanced flavor over time. In West Coast IPAs where pronounced bitterness is desired, it serves as a structural ally while contributing remarkable aroma. BRU-1 pairs beautifully with Loral, Chinook, and Citra.

Spectrum: The Dry Hop Revolution

Get all the alpha acids and aromatic compounds of hops — without vegetal matter. Maximum efficiency and guaranteed yield…

SPECTRUM offers numerous advantages over hop cones and pellets.

Fully soluble at fermentation temperature, you will lose no beer and spend less time cleaning.

SPECTRUM can fully or partially replace cones and pellets during Dry Hop.

Using Spectrum:

1kg of Spectrum = between 5kg and 8kg of pellets.

It is entirely possible to use Spectrum at 100%.

However, if you’re repeating well-calibrated recipes, Barth Haas recommends trialing and using 20% to 50% of your Dry Hop with standard hops, adjusting dosage based on the ratio above.

You can gradually work your way up to 100% Spectrum.

As shown in the chart above, the optimal point to use Spectrum is during secondary fermentation. The earlier you add it, the more you'll need — and the fruitier the result. The later you use it, the less you'll need — and the “green” hop notes will be more prominent.

Note: This product is specifically intended for Dry Hop. Spectrum does not contain iso-alpha acids, but does include non-isomerized alpha acids that, in high doses at the end of boil or whirlpool, can intensify bitterness — particularly in hazy beers where it may be undesired.

Storage:

Barth Haas recommends storing the product between 2°C and 15°C. A dedicated fridge is ideal.

The 1kg format is resealable; it's advised to purge headspace before sealing.

The manufacturer recommends using the product within one year of its production date (marked on the pouch).

Additional Benefits of Spectrum:

Brewery tests have shown that the risk of Hop Creep is drastically reduced compared to using T90 pellets. This is due to the absence of enzymes that restart fermentation.

The lack of solid matter leaves far fewer residues on your fermenter walls. You'll therefore use less product and less time cleaning your equipment.

Finally, Spectrum also reduces the risk of oxidation in heavily hopped beers.

Unlike pellets and cones, this product leaves no room for oxygen. Spectrum guarantees precise Dry Hop dosing without introducing oxygen.

Testimonials:

“SPECTRUM helped us increase our dry hop inclusion rates while minimizing beer loss in the process. This combination allows us to craft world-class beers with world-class manufacturing efficiency.” — Ross Koenigs / New Belgium Brewing

“We observed lower and more consistent beer loss in the batches where we tested it. We're very impressed by the aromatic profile Spectrum provides. We've used it for up to 50% of the dry hop in one of our beers, which significantly reduced tank time thanks to less hop creep and lower VDK (Vicinal Diketones).” — SOPHIE DE RONDE / Burnt Mill Brewery
