Spectrum is 100% natural and 100% hop derived. It is prepared from hop pellets by specific extractions. No additives, solvents or carriers are included in the formulation. Spectrum is dispersible in beer and is an alternative product to standard dry hopping.

Spectrum does not contain iso alpha acids, but (like pellets) it does contains unisomerised alpha acids that in high doses or late dosing can increase bitterness, particularly in hazy beers.

Spectrum is used for dry hopping, ideally dosed into (secondary) fermentation. The replacement rate for pellets with Spectrum is 1:5 to 1:8 when applied this way, so 100g Spectrum can replace up to 800g of T90 hop pellets. The higher the total dose rate, the less Spectrum is needed. It is not recommended to dose more than 1g/L Spectrum.
