Patty, there might be several things going on. First, there used to be more yeast in packets than there is now; it's about 2 1/4 teaspoons now, where before it was a scant tablespoon. More yeast, more aroma. Second, we think Fleischmann's has more old-fashioned yeasty aroma than other yeasts, so if you're not using Fleischmann's, give it a try. And finally, yeast manufacturing is always evolving: how long the process takes and the medium in which the yeast cells are grown. This could have contributed to diminished aroma, as well. As could the fact that many modern recipes simply call for less yeast (and a longer rise) than their earlier predecessors. as I said, many possibilities! Good luck - PJH
