VacBrew: Ultimate Flash Cold Brew Recipe

This is a rapid vacuum-accelerated immersion cold brew that produces a smooth, balanced cup in about 12 minutes (vs. traditional 12–24 hours). It uses a hot bloom for better saturation and CO₂ release (inspired by pour-over), then adds cooler water for controlled extraction, with vacuum pull at the end for full flavor without excess bitterness.

• Ratios (1:10 coffee-to-water, concentrate-style for serving over ice):
  • Single serve: 30g coffee grounds → 300ml total water → ~300ml yield (strong concentrate; dilute/serve over ice).
  • Big batch: 50g coffee grounds → 500ml total water → ~500ml yield.
• Grind: Medium-fine to medium (not specified exactly, but suits immersion + vacuum; experiment based on your grinder).

Step-by-Step Brewing Process

1. Grind your beans and add grounds to the VacBrew brewer chamber.
2. Hot bloom: Pour hot water (~90°C from electric kettle) just enough to saturate the grounds evenly. Let bloom for 30 seconds (releases trapped CO₂ for better extraction).
3. Add remaining water: Pour in the rest with cold water.
4. Stir: Use the included orange stirrer to mix for about 1 minute (ensures even extraction).
5. Select program: Press the blue light timer program (press 3 times, then hold to activate). Wait 12 minutes for immersion brewing.
6. Vacuum extraction: At the end of the timer, the vacuum pump automatically applies pressure to pull the brew down into the glass carafe.
7. Serve: Pour over ice for maximum chill and dilution. Enjoy fresh for best flavor (reduced bitterness, increased sweetness). If storing extras, swap to the included extra lid and refrigerate the carafe.

Bean & Roast Recommendations

• Origin/Flavor Profiles:
  • African (e.g., Ethiopian Yirgacheffe): Fruity, floral jasmine notes.
  • Kenyan: Blackcurrant notes.
  • Brazilian or Indonesian: Dark chocolate, cocoa, caramel notes.
• Roast Levels:
  • Light: High acidity, unique fruity/floral notes → ideal for specialty enthusiasts chasing origin character.
  • Medium: Balanced (caramel sweetness, some acidity + bitterness) → most people's favorite.
  • Dark: Roasty, dark chocolate, low acidity, intense/spicy → for traditionalists.
• Processing:
  • Natural: Sweeter, juicier (like ripe apple).
  • Washed: Cleaner, highlights terroir/bean characteristics.

Grinder Advice

• Conical burr (e.g., Comandante C40): More balanced, heavier body, round/smooth mouthfeel; forgiving for dialing in.
• Flat burr (e.g., 1Zpresso ZP1, or 64mm SSP MP on Turin DF64): Higher clarity/brightness, sharper taste; reveals individual notes (good and bad) but less forgiving.

Brand & Value Notes

• VacBrew (from Hong Kong-based brand pushing coffee innovation) delivers rapid cold brew in minutes at a competitive price (~$99.90 USD).
• It rivals pricier machines like Brezi ($399 USD) or Fellow Aiden (~$399.95 USD) at a fraction of the cost (about 1/4 the price).
• Mission: Elevate cold brew experience with vacuum tech for smooth, flavorful results quickly and affordably.
• Closing: "Happy brewing. And thank you for supporting VacBrew in this journey!"

This method blends immersion cold brew with vacuum acceleration and a hot bloom twist for a "flash"-like quick result—bright yet smooth, low-acidity, and ready fast. It's not traditional Japanese flash brew (hot pour-over over ice), but a vacuum-optimized hybrid for iced cold brew. ☕
