Hop Reactor Red IPA

Hop reactor is a red IPA powered by lupulin. Enjoy!

Nerd-dom comes in many forms. The first thing I nerded-out about was comic books. I spent so much money on my favorite books in high school I had a trunk full of books. When the Iron Man movies came out, I had an idea based on Iron Man’s arc reactor.

If you like the hop reactor symbol, I used it in a t-shirt design available for purchase.

Mash Bill

  • 12 lb 2-row pale malt
  • 2 lb Munich malt
  • 1 lb crystal malt 40 L
  • 0.5 lb crystal malt 120L
  • 0.25 lb chocolate malt

Mash at 152 degrees Fahrenheit for 60 minutes, sparge as required by your system to reach a boil volume of 6.5 gallons.


For extract brewing, replace pale malt with 8.25 lbs of light liquid malt extract. Steep the specialty grains for 30 minutes at 160 degrees Fahrenheit.


  • 1 oz Simcoe 13% AA – 60 minutes
  • 1 oz Centennial 10.5% AA – 10 minutes
  • 0.5 oz Citra 13% AA – 10 minutes
  • 1 oz Centennial 10.5% AA – 0 minutes
  • 0.5 oz Citra 13% AA – 0 minutes
  • 1 oz Centennial 10.5% AA – Dry Hop
  • 2 oz Citra 13% AA – Dry Hop

Dry hop after krausen has fallen back into the beer. Allow the hops to rest in the beer until fermentation is finished.


Ferment with a clean ale yeast. I’ve used Safale US-05 with good results at 70 degrees Fahrenheit.

But my new favorite yeast is Omega Yeast Labs OYL-057 Hothead Ale Yeast. From the first batch I made with this yeast, the clean fruity character made me realize it’s a great complement to an aggressive hop schedule with American-style hops.
