Yes, it would. As Jim suggested, the
Home Barista's Guide to Espresso was written to establish the foundational knowledge necessary to establish a common vernacular for productive forum discussions. You may also find Randy's
EASY GUIDE TO BETTER ESPRESSO AT HOME helpful. It covers many of the same topics in a pragmatic fashion.
Everybody in Italy drinks vacuum sealed Lavazza and I don't remember having bad espresso there!
Keep in mind that your expectations change over time (see
Hall of Shame: ''What I did when I was a newbie...'' for examples). Yesteryear's "very good" is today's "barely drinkable".
WHAT AM I DOING WRONG?!!
Even the best equipment can do little to improve tired, stale coffee. If the coffee is not freshly ground and roasted within the last 7-10 days, the resultant espresso will invariably be as you describe: Thin, bitter, with a flat, dull flavor. The solution:
- Freshly roasted coffee. Not "freshly scooped" or "freshly opened"... known roast date within 7-10 days,
- Consistent grinder designed for espresso (search will find you many discussions of solid value-oriented choices, as does the Unabridged FAQs if you search on 'grinders'),
- Espresso machine capable of delivering predictable brew temperature,
- Motivated barista willing to experiment, study, and listen to the advice of others.
With capable equipment, good fresh coffee, and a bit of patience, espresso is not that difficult to master. Unfortunately, the bulk of the entry level gear offered to newbies is the most difficult equipment to master, if it's even possible. Moreover, newbies frequently make a mistake of buying "Best By" coffee with recognizable brand names (I did). While it's not
impossible to pull a drinkable shot with such coffees, it's orders of magnitude more difficult than using truly fresh roasted coffee because the margin of error for past-prime coffee is razor thin.
