  1. Nero Aurum recommends no larger than a 1 liter batch size for brewing at home. With regular home storage, cold brew has a limited shelf life (3-5 days max). Only brew larger batches if you are sure you can use it in that time window.
     
  2. Make sure your water is cold; pre-chill in the refrigerator if needed. The goal is to brew below 4 degrees celsius (39F.)  For home brewing, big jars are preferred objects to use for cold brew.
     
  3. Grind 80 - 90 grams per liter (depending on preferred brew strength) on a medium grind setting. This should be finer than what you might use for a press pot.
     
  4. Add your freshly ground coffee to your chilled water and stir. You want to ensure that the you wet all the coffee. Seal the vessel and store in the refrigerator.
     
  5. After 1-2 hours, stir again. This will ensure that the coffee is incorporated with the water fully, rather than rising to & sitting at the top while off-gassing. 
     
  6. At the 22-23 hour mark, stir once more and strain. Decant the brew liquid through a metal strainer to remove larger particles, then strain again through cloth or polypropylene. Cloth is easily cleanable & re-usable; a woodneck brewer works well for this. You may have to clean the cloth in between batches to avoid it clogging with fine particles.
     
  7. Once filtered, cold brew should be stored in a refrigerated minimal oxygen environment. The easiest way to achieve this is by storing it in a sealed vessel that is completely filled, so that there is minimal headspace. 
  1. Enjoy your cold-brewed Nero Aurum Coffee. Remember, the coffee is very concentrated so when served, you can add water, (coffee) ice-cubes, hot or cold milk and/or sugar if your prefer. Try and find your favorite!
