Depends also of the climate you're at.
We used to have 'normal' 20-30 years ago that if you do not get the car hot for a long time at least couple of times a week (if driven daily) during winter when the temps do hover between 30-0 F, then the oil cap looked just like on the OP's picture. Summer was never a problem.
Also, the coffee color stuff is so small amount, that makes me to believe the current colder weather could be the culprint of this - or very recently started small mix of water to oil.
