This is the recipe Maestri House publishes for this brewer, and it is what Cold Brew Studio opens with when you pick it. It makes about 4½ cups, best straight over ice.
How the maker does it
Official MHCB02 instruction manual: fill the container with 1200 ml purified water (marked on the container body scale) and add coffee grounds to the powder cylinder per the desired coffee-to-water ratio: 1:10 = 120g, 1:12 = 100g, 1:15 = 80g, 1:20 = 60g (all against the same 1200ml fill). Use coarse grounds 'similar to breadcrumbs.' Gently shake to saturate, refrigerate upright or lying flat, and steep 12-24 hours (consume within 24 hours of brewing). Unscrew and drain the filter basket to separate the grounds from the finished brew - no separate post-brew dilution step is specified; the chosen ratio is the drinking strength.

The recipe, by strength
Each one fills this brewer as far as it honestly goes. Numbers are for a light roast steeping in the fridge.
| Strength | Ratio | Coffee | Water | Steep | Makes | Drink it |
|---|---|---|---|---|---|---|
| Everyday | 1:9.5 | 120 g | 1,140 mL | 18–22 h | about 3¾ cups | straight over ice |
| Strong | 1:7.5 | 120 g | 900 mL | 18–22 h | about 2¾ cups | with a splash of milk |
| Jet fuel | 1:5.3 | 120 g | 636 mL | 18–22 h | about 2½ cups | cut with a little water or milk |
| Concentrate | 1:4.5 | 120 g | 540 mL | 18–22 h | about 2½ cups | mixed 1:1 with water or milk |
If your beans are darker
Darker roasts give up their flavor faster, so they brew at a slightly wider ratio and steep for less time.
| Roast | Ratio | Coffee | Water | Steep in the fridge |
|---|---|---|---|---|
| Light | 1:9.5 | 120 g | 1,140 mL | 18–22 h |
| Medium | 1:10 | 120 g | 1,200 mL | 14–18 h |
| Dark | 1:10.5 | 114 g | 1,200 mL | 10–14 h |

Good to know
Integrated 350-mesh filter cylinder plus a printed ratio table (1:10-1:20, 120g-60g against a fixed 1200ml fill) means it's designed to brew straight to final drinking strength rather than a concentrate-then-dilute method - just pick the ratio for the strength you want instead of diluting afterward. Otherwise standard coarse grind and steep apply.
This brewer takes about 120 g of coffee at most. Stronger recipes can’t add more grounds, so they use less water instead. That is why every strength comes in under the full 1,200 mL.
