It would be easy to say the single most significant change was buying a quality grinder and developing a relationship with a coffee roaster. But I think there is more to it than that. The single most important thing I did was make a conscious decision to learn how to make great espresso at home.
Along that path I learned that high quality fresh coffee is necessary, a high quality grinder is necessary, a quality pump driven or lever espresso machine is necessary, and finally a boatload of personal experience is necessary. The first three are easy enough. Anybody with money can buy them. The last one is the zinger, it's mostly all on you. Aside from paying for qualified personal training, no amount of money will help a person understand how to make espresso. This must be learned. No amount of money will teach you to be consistent in dose and distribution. Again, this must be learned.
Everybody says you need fresh beans. If you have not used fresh roast dated beans, you will not understand the difference between fresh and stale coffee. When you understand the difference there is no option. Once I started using roast dated beans there was no going back. Now, if I run out of fresh coffee, which is not often, I simply do not attempt to make espresso until I have fresh coffee again. It is that frustrating and unpleasant to use stale coffee to make espresso. It does not matter what quality the grinder and machine are, stale beans just plain suck.
Everybody says you need a high quality grinder. If you have not used a commercial quality espresso grinder you will simply not understand the difference. I had a Infinity, a stepped conical grinder with 4 whole settings in the espresso range. I was switching between 1step too fine up to the next coarse setting while grinding to dial in that perfect timed shot. I could get between 20 and 30 seconds pretty consistently but I was still covering my spro with milk. Getting a 20 or 30 second shot at 1.5 - 2.5 oz does not guarantee success in the cup. Now that I have a quality stepless grinder I would never try to make espresso with anything less.
Everybody says you need a quality machine. Until you understand how different machine dynamics and components will affect the process you will not understand what to look for in a quality machine. I have owned 3 different consumer class, pump driven, espresso machines from 3 different manufacturers at 3 different price points. I can confidently say they were all very different. Spending more did not necessarily equate to a better machine. I had to go through 2 "upgrades" before I made it to a quality entry level machine.
Even after you have fresh coffee beans, a quality grinder, and a good machine it still takes a lot of trial and error to start to understand anything. Keep notes, read tips, try to apply what you read, taste and repeat. Try not to get frustrated there is a lot to take in.
One thing that would really get me stymied was malachi's tip that all you need to do is go by taste. WTF does that mean! My spro tastes awful now what? Now I find it to be one of the most important and profound tips available. I think it means just what it says. Go by taste. If your espresso tastes bad, something is wrong and you should keep practicing until you understand what it is that is wrong and then correct it. As you practice and gain experience your skills will grow, your palate will become more refined and your understanding of the results will develop. When this happens, going by taste will make perfect sense, and will be your primary diagnosis tool.
