How to Brew 500ml of High-Quality Vietnamese Coffee at Home
Have you ever wondered how coffee shops serve so many cups of filtered coffee so quickly? Unless you order a black filter coffee, drinks like Bac Xiu or Iced Brown Coffee typically use pre-extracted coffee to speed up the service. But how do they ensure consistent quality across 100 cups of coffee?
Today, I'll show you how to extract 500ml of rich, flavorful Vietnamese coffee in one go using a 200-gram aluminium coffee filter. This method guarantees a consistent, high-quality brew every time.
200 gram coffee filter
Two Common Preparation Methods:
For 200 grams of coffee, extract 400ml of coffee essence.
For 250 grams of coffee, extract 500ml of coffee essence.
Tools You’ll Need:
Stopwatch (or phone timer)
Electronic scale
200-gram aluminium coffee filter
Spoon
Step-by-Step Brewing Process:
Step 1: Preheat the Filter
Rinse all parts of the coffee filter with hot water to:
Sterilize the filter.
Maintain a consistent brewing temperature.
Reduce coffee residue after extraction.
Step 2: Prepare the Coffee
Place 250 grams of ground coffee into a large bowl.
Step 3: First Bloom
Add 150-200ml of boiling water (98-100°C) to the ground coffee.
Watch as the coffee blooms, releasing its aroma and allowing the coffee to soak in the hot water.
During the blooming step, if the coffee grounds aren't evenly saturated, some areas may remain dry while others are wet, leading to uneven extraction. To fix this, add a little more hot water as needed to ensure all the coffee grounds bloom evenly.
Step 4: Mix and Load the Filter
Stir the coffee gently with a spoon to ensure all grounds are evenly dampened.
Add the coffee grounds into the filter and close the lid.
Stir the coffee gently
Step 5: First Extraction
Use the compressor to press the coffee evenly.
Pour 300-400ml of hot water to fill the filter.
Close the lid and let the coffee extract for 20-30 minutes.
Step 6: Second Extraction
Open the lid and pour in 100-150ml of hot water.
Close the lid and brew for another 15 minutes or until extraction is complete.
