1. What is Cold Brew Coffee? ❄️
Cold brew is a slow-extracted coffee made by steeping coarse-ground coffee in cold water for an extended period (12-24 hours).
✔ No heat involved – Uses time, not temperature, to extract flavors.
✔ Lower acidity – Up to 67% less acidic than hot-brewed coffee.
✔ Naturally sweeter – The slow extraction highlights the coffee’s chocolatey and caramel notes.
✔ Highly concentrated – Can be served straight or diluted with water/milk.
💡 Fun Fact: Cold brew lasts up to two weeks in the fridge, making it a great make-ahead coffee option!
2. Cold Brew vs. Iced Coffee: What’s the Difference? 🆚
| Feature | Cold Brew | Iced Coffee |
|---|---|---|
| Brewing Method | Steeped in cold water for 12-24 hours | Brewed hot and then cooled |
| Acidity | Low acidity, smooth flavor | Higher acidity, can taste sharp |
| Bitterness | Naturally sweet, low bitterness | Can taste bitter when chilled |
| Caffeine Strength | Stronger (more caffeine per ounce) | Weaker caffeine content |
| Shelf Life | Up to 2 weeks in the fridge | Best consumed immediately |
💡 Best For: If you love strong, smooth, less acidic coffee, go for cold brew!
3. The Perfect Cold Brew Ratio ⚖️
The strength of your cold brew depends on the coffee-to-water ratio.
✔ Standard Ratio – 1:8 (1 part coffee, 8 parts water) = Balanced flavor.
✔ Strong Concentrate – 1:4 = Bold and intense, can be diluted.
✔ Mild Brew – 1:10 = Light and refreshing.
💡 Best Practice: A 1:8 ratio is perfect for most people—strong but smooth!

🚫 Not Steeping Long Enough – Less than 12 hours results in weak coffee.
🚫 Over-Steeping – More than 24 hours can lead to a harsh taste.
