Spectrum: The Dry Hop Revolution

Capture all alpha acids and aromatic compounds from hops — without vegetal matter. Maximum efficiency and guaranteed yield…

SPECTRUM offers many advantages compared to cones and hop pellets.

Fully soluble at fermentation temperature, you’ll 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 5 and 8kg of pellets.

It’s absolutely possible to use Spectrum at 100%.

However, if you’re repeating well-balanced recipes, Barth Haas recommends testing and using 20% to 50% of your Dry Hop with standard hops, following the conversion ratio above to adjust your dosage.

You can gradually work your way to full usage.

As shown in the chart, the ideal time to use Spectrum is during secondary fermentation. The earlier it’s added, the higher the dosage and the more prominent the fruity aromas. The later it’s added, the lower the dosage and the greener hop notes will stand out.

Note: This product is specifically designed for Dry Hop. Spectrum does not contain iso-alpha acids, but it does contain non-isomerized alpha acids which, in high doses at the end of the boil or in the whirlpool, can intensify bitterness — especially in hazy beers where this isn’t desired.

Storage:

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

The resealable 1kg format should be purged of air before closing.

The manufacturer advises using the product within one year of the production date (shown on the pouch).

Additional Benefits of Spectrum:

Brewery trials have shown a dramatically reduced risk of Hop Creep compared to using T90 pellets. This is due to the absence of fermentation-reactivating enzymes.

No solid matter means fewer residues on the fermenter walls. You’ll use less product and less time cleaning your equipment.

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

Unlike pellets and cones, this product eliminates oxygen exposure. Spectrum ensures precise Dry Hop dosing with no oxygen introduction.

Testimonials:

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

“We saw lower and more consistent beer loss on the batches where we tested it. We’re very impressed with the aroma profile Spectrum delivers. We used it up to 50% of the dry hop in one of our beers, which significantly reduced tank time thanks to lower hop creep and reduced VDK (Vicinal Diketones).” — SOPHIE DE RONDE / Burnt Mill Brewery
