Cold Brew

Buy This If…

It’s hot outside and you’re having 20 friends over for a backyard BBQ which you’ve just decided will start with a cold brew and end with cold beers to follow.


  • Prep Time: 5-7 min
  • Brew Time: 12-24 hours
  • Cups: 24 cups (add water to dilute if too strong)
  • Brew ratio: 1:4.4
  • In your mouth: Balanced and full-bodied with a long sweet finish
  • Grind size: As coarse as your grinder will go


  • Filtron
  • Filtron felt filter
  • 453 grams (1lb) of whole beans
  • 2000 grams of water
  • Burr grinder
  • Kettle


  • Use a brew ratio of coffee to water that is 1:4.4
  • Grind 453g (1lb) of coffee on the coarsest setting possible.
  • Insert rubber stopper into the Filtron and seal tightly.
  • Pre-wet the felt filter with boiled water and place it in the bottom of brew device.


  • Pour all ground coffee into the brew device and shake to evenly disperse.
  • Add 2,000g of water and be sure to saturate and submerge all of the coffee grounds.
  • Place plastic disk on top of the grounds, which helps to achieve even extraction.
  • Put the top on the Filtron.
  • Let the brew device sit for 12-24 hours.
  • A 12 hour brew time will produce a thin body and at 24 hours the body will be thick.
  • At your desired time, pull the plug and let the coffee concentrate drain into a glass jar or pouring device that can hold 2000g of water.
  • When you pour into individual glasses, use (one) part concentrate to (three) parts milk, cream, or water.
  • Throw some ice cubes in and stir.
  • Guzzle!
