Bloom is a slightly foamy head that forms on top of coffee while brewing, most notably when the coffee is fresh. Freshly roasted coffee contains a good deal of gas within the bean structure, as a by-product of the roasting process. That gas will dissipate over time, especially after grinding. A nice bloom, usually tan to red-brown in color, is a good sign that coffee is fresh. However, that has very little to do with the final taste in the cup. It is a symptom of certain physical conditions, and not in the quality of beans or roast, nor the skill of the brewer.

when you have good fresh roasted coffee and you grind it right before you brew it and then hit those fresh roasted and ground coffee grounds with hot water, it'll swell up, bubble up, to wit: bloom, right before your eyes as it releases the gasses within. It's an amazing process of which I was completely unaware when I was using grocery store coffee.
