We are a Southern California company and we will not be apologising for it. But there is a case to be made for going north, and the case is roughly four hundred miles long and takes two days if you do it properly.
Half Moon Bay is where the fog stops pretending. In Laguna the marine layer is a morning inconvenience that burns off by ten and everybody forgets about it. Up here it simply is the weather. It arrives, it stays, it turns the cypress into silhouettes, and it makes an extremely strong argument for drinking something hot outdoors while wearing a coat in June.

The drive is the point. You can take the 5 and be there in five and a half hours having seen nothing but almond groves and a Harris Ranch smell you will remember against your will. Or you can take the 1, lose an entire day, and arrive having actually been somewhere.
Take the 1. This is not a close-run thing.
Somewhere around Big Sur you will stop being able to hold a coffee and drive at the same time, which is a good reason to bring cold brew in a bottle rather than something hot in a cup with a lid that lies about being spill-proof. We are aware this is convenient for us to say.
What the fog does to coffee
Nothing chemical. But it does something to how you drink it, which is not nothing.
In fifty-five degrees and damp, the aromatics you spend all that money on are dulled — cold air carries less of them to your nose, and your nose is where most of what you call taste is actually happening. A bright, delicate, floral Ethiopian that sings in a warm kitchen will go strangely quiet on a bluff. What works up there is something with body and sugar to it: a natural process, a heavier Brazilian, anything with chocolate in the notes rather than jasmine.
This is not a rule so much as an observation made repeatedly while being cold.
It was 2018. The company had been shut for two years and we were, on paper, no longer in the coffee business. We still brought a grinder in the boot. There is not really a defence for that.
