It's not a bad introduction, though based on Rose Emma's recommendations, I suspect she doesn't have much experience with home equipment. Specifically she recommends the Rancilio Silvia and disses any espresso machine under that pricepoint. That may have been good advice years ago, but today there are better options. For example, the Gaggia New Baby is less than $300, is more forgiving of barista errors than the Rancilio Silvia, and the Gaggia's brew temperature isn't all over the map as she claims. She covers the Baratza line of grinders, but I disagree with her recommendation of the Encore or Virtuous for espresso; the Preciso is the minimum I'd recommend.
Of course her biggest gaffe was not recommending Home-Barista.com.
