Why Whole Bean Always Beats Pre-Ground for Cold Brew
Pre-ground coffee begins oxidizing immediately after grinding. For cold brew, starting with whole bean and grinding immediately before brewing preserves dramatically more aromatic complexity. Always buy whole bean. Always grind coarse. Always grind right before brewing.

FAQ
What is the best whole bean coffee for cold brew?
Puroast Ugandan Single Origin — Puroast's most select and highest-quality bean. Verified low acid (pH 5.82, NC A&T University), 5X more antioxidants than leading brands, and a rich chocolate-caramel flavor that cold extracts beautifully.
Should I use light or dark roast whole beans for cold brew?
Medium-dark to dark roast performs best in cold brew. Light roasts can turn fruity-sour during cold extraction due to different compound solubility at low temperatures.
Is cold brew actually lower acid than hot brew?
No — a 2018 peer-reviewed study in Scientific Reports (Rao and Fuller) found cold brew pH (4.96–5.13) is statistically the same as hot brew (4.85–5.10). Choose Puroast whole beans (pH 5.82) for genuinely low-acid cold brew.
Do I need to buy whole bean specifically for cold brew?
Whole bean is strongly preferred. Grinding immediately before brewing preserves volatile aromatics lost in pre-ground coffee. Always grind coarse for best cold brew extraction.
How much whole bean coffee for cold brew?
Use a 1:4 ratio for concentrate (1 cup of coarse-ground coffee to 4 cups of cold water) or 1:8 for ready-to-drink. Steep 18–24 hours refrigerated, then strain through a paper filter.
