Notes

15 MINUTE WHIRLPOOL WITH HOP ADDITIONS @ START

The amount of teaspoon and rinse water you should use depends on the equipment and method you are brewing with. As an estimate, we can say that you can use 20 l of tap water and 13.3 l of rinsing water for this beer. Some brewing machines (eg Speidel Braumeister) may require larger quantities of mesh water. Always check the manual of the equipment you are using.

Measuring at 149 degrees for 75 min. Excellent at 168 degrees for 5 min if you have the opportunity to increase the temperature of the blade.

Cool down to 15 degrees before pitching the yeast.

Fermentation at 60 degrees until storm fermentation begins to subside (typically after 3-5 days). Then increase to 68 degrees and hold the rest of the fermentation period (14 days in total).

Yeast options: WLP011, WLP036, Safale K-97

Target water profile is balanced or Pilsen. pH 5.3 - 5.4 (Pilsen Style requires < calcium)
