Weaver is a demi-god in the coffee roasting world. Like over 30 years roasting. His coffees do have subtle differences and if you french press the different roasts you really get the true "taste" of the coffee. Most shops may or may not pull a great espresso but their cafe pulls a rocking double espresso with a kick ass crema. I may not be saying it right but I know what I like and I like the coffee. I even turned on my friends to weavers - and they turned on their friends to weavers. They have like 20 something coffee's and killer teas too! There is a cool cafe in San Rafael - hard to find but worth the effort - there is no attitude in their cafe - unlike other roasters who are RIDICULOUS on attitude.
The antique roaster in the place was Peets. it is super cool and if you can catch Weaver there he can tell you the story about it. He worked with Peet a long time and there is a letter from him in their cafe. You can watch the guy roast the freaking coffee through the window --- I love their coffee and drink it all day. Their House is a good value and their chamomile tea puts me to bed at night.
