80 g Carafa Special Type III (710.7 SRM)

Crush guaraná beans and infuse in 1 quart of hot boiled water (max temperature 78 °C).
Filter the mixture and add to the boiling wort the last 15 minutes.
Mash crushed grains at 66 °C in 135 L of water.
Hold mash at 66 °C for 60 minutes.

Boil wort for 60 minutes.
Add the Guaraná mixture the last 15 minutes and the Willamette hops the last 7 minutes.
Cool wort to 19.5 °C and transfer to clean and disinfected fermenter. Remember to aerate the cooled wort, dissolving as much oxygen as possible in the wort.
Pitch yeast.
Ferment at 19.5 °C until fermentation is completed (about 7–10 days).
Dissolve 90 g of sugar in a small amount boiling water.
Put the sugar mixture in a clean and disinfected container, and transfer the fermented beer to it. This will ensure even distribution of carbonation sugar. Leave as much yeast sediment/trub as possible in the fermenter. Be careful not to aerate the fermented beer in the process.
