Frequently Asked Questions

What is the best coffee-to-water ratio?
The Specialty Coffee Association recommends a 1:15 to 1:18 ratio for drip and pour-over. French press works best at 1:12 to 1:15. Espresso uses a much more concentrated 1:1.5 to 1:2.5 ratio.
How long should cold brew steep?
Cold brew should steep for 12-24 hours in the refrigerator. A 1:5 ratio produces a concentrate that can be diluted with water or milk at a 1:1 ratio when serving.
