I forget who it was, but who was doing the coffee roasting at home? I have some questions, my latest few batches, while they turn out find, the crema is quite bubbly after pulling a shot. I did the roast about a week or so ago, so I presume that the beans have had enough time to de-gas and that it isn't just a lot of CO2 - though once I pour the shot into a latte cup the large bubbles break.
