• Cold brew success hinges on four variables: coffee-to-water ratio, grind size, steep time, and filtration. With RAMI Coffee's medium roast, a 1:8 ratio, coarse grind, and 18-hour steep at room temperature yields a smooth, concentrated base. Always filter twice for clarity and adjust to taste.
• Use a 1:8 coffee-to-water ratio for a concentrate; adjust to 1:5 for stronger or 1:10 for lighter.
• Grind coarse—like breadcrumbs—to avoid over-extraction and bitterness.
• Steep 18 hours at room temperature; longer isn't always better.
• Filter twice: once through a sieve, then through a coffee filter or cloth.
• Taste and adjust: if bitter, reduce steep time; if sour, grind finer.
