I just had an espresso at a café, and it really put into perspective how weak my everyday coffee is. All the equipment I own is a blade grinder, and my method is a turkish brew (grind the beans, put them in the cup, pour-over some boiling water, wait for it to sink, done!).
What can I do to get stronger coffee? And more precisely, what will make the most difference?
Note that I am not willing to buy any new equipment or machines; I'm asking about what I can do with what I've got.
Update: tried adding grounds onto boiling water, instead of pouring water over grounds. Here's how it went:
No success, strength did not increase and taste just got worse.
What I did: I took my strongest beans, ground them as fine as possible, used two identical cups, divided the grounds into two equal portions (on a separate tray). I put grounds first, boiling water afterwards in the first cup, and did the same thing but backwards on the second one. I did not stir any of the cups after adding all ingredients. After quite some time I tasted both cups, I am now finishing them both up while programming.
Observations: The grounds on the "water-first" cup took a considerable time to sink into the liquid. Even after the brewing time had passed, much more grounds were floating around there than in the "pour-over" cup. Also, the water-first cup had almost no foam, which the pour-over cup had plenty of.
Results: The water-first cup was not stronger than the pour-over; if anything it tasted weaker. The taste was quite different too, water-first tasted a bit stale/watery (not much but there was a clear difference). Pour-over had a rounder and more full aroma, liked that one more. And the crema/foam looked a lot better on the pour-over as well.
