Just did the Scharffen Berger tour on Monday. They did a very nice
job talking about the beans used, where they are grown, how it is
roasted and blended. etc.

They were kinda shy with samples, had a bit of 41%, and 72%, got to
taste Nibs and a bit of a 99% sauce that was to die for.

Surprised at how small the factory building was, but seems that there
is a nice lunch restaurant attached,

In Berkeley, CA, where parking is horrible. Tour took about an hour.

I'd recommend it.
