Nowdays, I tried some recipe for my aeropress, and I found interesting brew method that I'm calling "DGBM". The meaning of DGBM is Double Grinding Brew Method.

Yeh, actually, I use two different grind for one cup of aeropress brewing.
Here, my key routine. That is quite easy and adjustable as your taste.

#1. Prepare a aeropress in regular position, but don't using invert method.
#2. 10 grams coffee ground on the grinder, little coarser than paper filter.
#3. 100 grams of water at 93c for the bloom and brew coarse particles about 50s. You stirring slowly and enough.
#4. During the #3 blooming, grind 10g coffee very fine.
(turkish to espresso range ; just same coffee but different grind)
#5. After #3, add grinds(#4) to above floating particle layer that is made from #3. And pouring extra 100g water onto fine grinds enough. Stirring slowly but you remember don't stir too deeply. Important thing is that retain bottom's coarse layer stably.
#6. After another 50s, press gently for half or one minute.


After brew, you can find a interesting inverted particle gradation on a puck that is contrary to standard method.

I could get very deep and sweet cup without over extracted nuance and any odor.
And I feel it is a best method with cheap and popular grinder like my baratza encore.

I guessing two different distributed grinds are making new balanced flavor profiles. I'll have to more testing with refractor meter after work but there is not only yield validity but also flavor profile from different grind.

Just try, and I hope to listen your thought.

# more information :
I use DGBM with very light roast bean that is usually hard to fully extractions.
And brew(water/coffee) ratio is not a constant, so you can adjust brew ratio and coarse / fine grind ratio and each brew time.
My DGBM experience was best with metal filter. Enjoy!

Okay, I tried this method this evening.

Awesome!
Yeh, I missing some information about roast and filter. I like the DGBM with especially very light roast beans and metal flters. What roast did you use? And it's good to add some more waters 50~100g.

Roast was in fact a light roast.. C+. My own blend consisting of 50% Braz, 25% Bali, and 25% PNG, all C+ roasts. Rested for 1 week. Typically bright thirdwave coffee.

Filter was AP stock--the white filters that come with the device.

Normally the cups I make with the stock setup is a very clean cup.. The "Turkish to Espresso" grind I used allowed much of the fines in the grounds to slip right through, thus a very murky looking cup. I imagine with a metal filter, there would be a magnitude greater amount of fines in the cup..

And as you might have noticed, the grinder I am using is a Baratza Forte BG, 'BG' designated for brew grinding duty.

Interestingly the brew ratio I normally use is a bit more diluted than this.. Yet the 20 grams of coffee to 200g of water in this brew test yielded a far weaker, flat cup. It was not bitter but it was not flavorful either. It does remind of very much of Turkish coffee, actually (which i find quite bland).

I noticed in your puck that it has a heap at the top.

Thanks for your reply!
Yes, I didn't fully press it, so not squeezing
Your first pour was lack of some water, how about add more water? Total mixture's about 250ml, I guess.

I'll make some clip tonight add it in this thread with my single origins guat.
Usually post my experience with AP was good enough but with light roasts has little lack of sweetness and complexity.
Maybe there are some more spot where we didn't reach. Try and tweak and tweak!

Okay, I just tried again... this time I made the following changes...

1. ground coffee in advance.
2. increased water volume by 1.5oz
3. refrained from compressing the puck
4. stirred more carefully for a better bloom and integration.

Result:
Negligible improvement. Still terribly lifeless. Less cloudy but still too cloudy for my taste. I needed to redeem myself and did a normal AP brew to ensure nothing was out of the ordinary. It tasted great.. Smooth, clean and lively.

Puck:

Good try! If your coffee already great, you don't need another approach!
I appeciate your effort! Thanks!

Agreed. It was a fun experiment.

Here, my routine.
This time >> Guatemala San Gerardo
1st phase : 14.5g coarse grind / 150g water / 40sec
2nd phase : 6.5g fine grind / 70g water / 50 sec

After brew, I add 100g more water.
Pretty tasty to my bud.
