Development Time and Roast Level

Development time should be interpreted relative to the intended roast style. In one discussion, a short development time was described as acceptable for filter or omni-roasts, but not sufficient when targeting darker roasts, medium roasts, or City+ style outcomes. Because the exact duration of “short” was not specified, this should be treated as directional guidance rather than a fixed time rule. source

Practical Takeaway

• For filter or omni-roast profiles, a shorter development phase may be appropriate if the roast tastes balanced and sufficiently developed. source
• For medium, City+, or darker roast goals, plan for more development than would be used for a short filter-style finish. source
• Do not apply this as an absolute rule without considering first crack behavior, rate of rise, end temperature, color, weight loss, and cup results.
