I typically roast and consume my beans within 7-10 days and recently had a revelation at 13-14g vs. 18g. The acidity of my espresso went from slightly sour to crisp and clean. So I am now a big proponent of getting out the gram scale and doing some experimentation on grind and dose. I was surprised to find that my results correlate with Jim's paper.
