I wonder if adding an I2C CO2 monitor might not also provide some insight into how active the starter is - it could be overkill, though, if CV is already doing a good job.
There's a few MQ sensors[1] that would probably work well for something like this. Sensors like the MQ-3[2] are sensitive to alcohol, which could be used to help minimize hooching[3].
There's a great blog post[4] about using MQ sensors for "machine olfaction" to monitor things a human would normally smell with their nose. Definitely worth checking out!
