Craving a smooth, refreshing cold brew? Choosing the right coffee beans can make or break your drink. This guide compares the best coffee beans for cold brew, covering flavour profiles, roast types, varietals, and brewing tips to satisfy your taste buds. Backed by expert insights and recent studies, we’ll help you pick the perfect beans for a bold, low-acidity cup.
What Makes Coffee Beans Ideal for Cold Brew?
Cold brew beans deliver a robust flavour with low acidity, thanks to their 12–24-hour steeping process. Medium to dark roast beans with chocolatey, nutty, or fruity notes excel in cold extraction. A 2023 study from the University of California, Davis, Food Science Department, found that coarsely ground beans retain 20% more flavour compounds than fine grounds. Wet-processed beans, which enhance clarity and sweetness, outperform dry-processed beans by 15% in cold brew, per a 2024 Coffee Science Foundation report.
- Key Factors: Bean origin, roast level, varietal, grind size, freshness.
- Best Profiles: Chocolate, caramel, berry, or nutty notes.
- Why It Matters: Cold brew’s long steeping amplifies bold flavours.
