Hello, my husband and I got a great home espresso machine about a year ago and have had fun trying different beans and experimenting with it. Just as we'd settled on some favorites - I find out I'm pregnant. Now, I know that caffeine is fine in limited quantities, but on the days where I want a second cup, I'd really like to have a decent decaf alternative. Can anyone recommend a Bay Area (or beyond) roaster that makes a decent decaf espresso roast? Many thanks!
