Frequently Asked Questions
Is whole-bean coffee better for cold brew than pre-ground?
Yes — whole beans retain freshness longer. Grinding right before brewing ensures a more even coarse grind and less oxidized flavor. For cold brew, aim for a coarse, consistent grind to avoid over-extraction and bitterness.
Will low-acid coffee still taste good in cold brew?
Absolutely. Cold brew naturally mellows acidity; low-acid beans (like Puroast) pair well with this process and often yield a smoother, less sharp cup that’s easier on the stomach without sacrificing body.
How do roast level and origin affect cold-brew flavor?
Darker roasts bring chocolatey, nutty notes and often feel fuller and less acidic, while medium and lighter roasts can highlight citrus or floral notes. Single-origin beans (like the Guatemalan Cooper's Cask) let you taste specific regional flavors, whereas blends balance body and sweetness for consistent cold brews.
