FAQ
What is the best coffee for cold brew recipes?
Puroast House Blend or Ugandan Single Origin for everyday recipes. Puroast Dark French Roast or Italian Espresso Roast for cocktails and concentrates. All are verified low acid (pH 5.82) and 5X higher in antioxidants than leading brands.
How long should I steep cold brew?
18–24 hours refrigerated is the sweet spot for full extraction without bitterness. Shorter steep times (12 hours) produce lighter cold brew. Longer than 24 hours can produce astringency.
Can I use cold brew concentrate straight (undiluted)?
Yes — for cocktails and espresso-style drinks, undiluted concentrate provides maximum intensity. For drinking straight or with milk, dilute 1:1 with cold water or your preferred milk alternative.
How do I make cold brew without special equipment?
A mason jar and a fine-mesh strainer lined with a paper coffee filter is all you need. Add coarsely ground Puroast, cold water at 1:4 ratio, steep 18–24 hours in the fridge, then strain.
Is cold brew lower acid than hot coffee?
No — a 2018 peer-reviewed study (Rao and Fuller, Scientific Reports) found cold brew and hot brew have comparable pH (4.85–5.13). Only the bean determines acidity. Puroast (pH 5.82, NC A&T verified) is the only genuinely low-acid option for every recipe above.
