The optimal coffee-to-water ratio for cold brew depends on how strong you want it. Here are two common ratios:

Cold Brew Concentrate (Strong):

1:4 ratio (250g coffee per 1L water) – This creates a concentrate that can be diluted with water or milk before drinking.

Ready-to-Drink Cold Brew (Mild):

1:8 to 1:10 ratio (100–125g coffee per 1L water) – This is a more balanced, smooth cold brew that you can drink as is.

For best results:

Use coarse-ground coffee (like sea salt texture).

Brew in the fridge or at room temp for 12–24 hours.

Filter and enjoy!

Standard Ratio (Golden Cup Standard):

1:16 ratio → 15–16g coffee per 250g (ml) water

Example: 30g coffee for 500g (ml) water

Stronger Brew (More Intense Flavor):

1:15 ratio → 16-17g coffee per 250g water

Lighter Brew (More Diluted):

1:17 ratio → 14-15g coffee per 250g water

Pro Tips for a Great Pour-Over:

Use medium-fine grind (like sea salt).

Water temperature: 195–205°F (90–96°C).

Bloom first: Pour a small amount of water (twice the weight of the coffee) and let it sit for 30–45 seconds before continuing the pour.

Total brew time: 2.5–3.5 minutes, depending on grind size and flow rate.

Standard Ratio (Golden Cup Standard)

1:16 ratio → 10g (about 2 tbsp) coffee per 160g (ml) water

Example: 60g coffee for 1 liter (1000ml) water

Stronger Brew

1:15 ratio → 10g coffee per 150g water

Example: 67g coffee for 1 liter water

Lighter Brew

1:17 ratio → 10g coffee per 170g water

Example: 58g coffee for 1 liter water

General Brewing Tips:

Use a medium grind (like sand) for even extraction.

Water temperature: 195–205°F (90–96°C) for best extraction.

Brew time: 4–6 minutes depending on the machine.

Use filtered water for a cleaner taste.

Coarse Grind (Like Sea Salt)

Best for:

Cold Brew (Slow steeping prevents over-extraction)

French Press (Prevents too much sediment)

Percolator (Prevents bitterness)

Grind setting: Largest setting on a burr grinder

Brew time: 12–24 hours (cold brew), 4 minutes (French Press), 7–10 minutes (Percolator)

Medium-Coarse Grind (Like Rough Sand)

Best for:

Chemex (Slows down flow rate, giving clarity)

Clever Dripper (Balance between steeping and filtering)

Grind setting: Slightly finer than French Press

Brew time: 3.5–4.5 minutes

Medium Grind (Like Beach Sand)

Best for:

Drip Coffee Machines (Mr. Coffee, Bonavita, etc.)

AeroPress (With longer brew time: 2–3 minutes)

Siphon (Vacuum Pot)

Grind setting: Middle range on a burr grinder

Brew time: 4–6 minutes

Medium-Fine Grind (Like Table Salt)

Best for:

Pour-Over (Hario V60, Kalita Wave, etc.)

AeroPress (Shorter brew time: 1 minute or less)

Grind setting: Slightly finer than drip coffee

Brew time: 2.5–3.5 minutes (pour-over), 1–2 minutes (AeroPress)

Fine Grind (Like Powdered Sugar)

Best for:

Keurig

Espresso (Fast extraction under high pressure)

Moka Pot (Stovetop Espresso)

AeroPress (Short, intense brews)

Grind setting: Almost the finest setting, but not quite espresso powder

Brew time: 20–30 seconds (espresso), 1–2 minutes (Moka Pot), 30 seconds (AeroPress fast method)

Extra Fine Grind (Like Flour)

Best for:

Turkish Coffee (Ultra-fine for unfiltered brewing)

Grind setting: Finest setting possible on a burr grinder

Brew time: Boiled 2–3 times in an ibrik (cezve) over low heat

Pro Tip: Always grind fresh right before brewing for the best flavor! Need help with grind settings for a specific coffee maker?
