This is our only ultra-dark roast blend. When it comes to iced coffee at our store, this is it! Not only in summer, but also in winter, add milk and sugar to take a breather, and arrange the black and strong bitterness... You can enjoy it in various forms. If you want to drink iced coffee at home, we recommend making a large amount of these beans and a coffee maker and storing them in the refrigerator. It's easy to make! Make strong coffee, add a large amount of ice to the brewed coffee, cool it quickly, and store it in the refrigerator. That's it. Iced coffee is diluted with ice, so if you don't brew it strongly, it will become watery. If I secretly write here some of the secret recipes I learned from my master... For 40g of powder, the extraction amount is 400cc Add 400g of ice to it and you're done. It is recommended to determine the concentration of coffee by the amount of powder. (The amount of extraction and the amount of ice dropped will not change!) ） ～DATA～ Brand Name Used; 2 species in Brazil, Colombia, Kenya, and Uganda (Robusta) Capacity ;200g Shelf life ; For frozen storage, 1 month after opening storage method ; Store in a cool, dark place as much as possible (freezer recommended) Powder coarseness ; Coarse grinding ~ medium grinding, it is easy to become thinner, so be careful to adjust the dial of the mill!
