Hybrid Hot Bloom Vacuum Cold Brew Recipe for VacBrew

This recipe creates a sweet and mellow coffee by combining a gentle hot bloom (using the Melodrip for even, low-agitation saturation to release gases and enhance sweetness) with a rapid vacuum-assisted cold steep in the VacBrew maker. The hot bloom extracts bright, sweet notes upfront, while the cold vacuum extraction adds smooth body without bitterness. Total water: 300ml (1:10 ratio with 30g coffee). Yield: ~250-280ml concentrated brew (serve over ice or dilute if desired).

Ingredients & Equipment

• 30g medium-light roast coffee (grind medium-fineness)
• 50ml hot water (93°C / 199°F)
• 250ml cold water (refrigerated or room temperature for mellow flavor)
• VacBrew vacuum coffee maker (brewing chamber, vacuum pump, carafe)
• Melodrip tool
• Gooseneck kettle (for precise pouring)
• Scale and timer
• Stirrer (included with VacBrew)

Steps

1. Prepare the grounds Grind 30g coffee fresh. Add to the VacBrew brewing chamber.
2. Hot bloom with Melodrip (1 minute) Heat water to 93°C. Position the Melodrip close to the coffee bed for gentle agitation. Slowly pour 50ml hot water through the Melodrip in a circular motion, ensuring full, even saturation without channeling. Aim for a gentle "rain" pour to degas the grounds thoroughly – you'll see blooming and CO₂ release. Let bloom for exactly 1 minute. This step boosts sweetness and clarity while pre-extracting soluble compounds.
3. Add cold water and start vacuum steep Gently pour 250ml cold water over the bloomed grounds (no need for Melodrip here – a normal pour is fine to avoid over-agitation). Stir lightly 3-5 times with the included orange stirrer to ensure even mixing.
4. Activate the blue light program Start the vacuum pump and select the blue light program (12-minute cycle for the strongest, fullest extraction). The vacuum will accelerate flavor pull-through, creating a smooth, low-acidity brew with enhanced sweetness from the hot bloom.
5. Finish and serve Once the cycle completes (vacuum pulls the coffee into the carafe), remove the chamber. Serve immediately over ice for a refreshing, mellow iced coffee, or chill further. Expect notes of caramel sweetness, soft fruit, and velvety body with minimal bitterness.

Tips for Best Results

• Use high-quality, fresh beans (light-medium roast shines here for sweetness).
• If the brew tastes too weak, grind slightly finer next time.
• For extra mellow: Dilute with a splash of milk or more cold water.
• Clean immediately – parts are dishwasher-safe.

Enjoy your sweet, mellow vacuum hybrid brew! This method leverages the Melodrip's precision for the bloom and VacBrew's vacuum power for fast, clean cold extraction.
