Hey guys! I'm new here, and I wanted to see if someone would be kind enough to help me with a problem. I recently purchased an Aeropress, and for some reason, my coffee tends to taste particularly sour. It's worth mentioning that I use hot water from my Keurig machine rather than using the microwave or stove. Could it be a water temperature issue?

I think I would start with hotter water. Sour coffee usually indicates the water is too cool.  Although Alan, the inventor of the Aeropress, suggests water at I think 170, I find hotter water is better.  A Keurig brews at 192, and is likely much less by the time you get it into your Aeropress.

Try water just off boil from a kettle.

All coffees, or one in particular? Can you share more about that coffee?

If you're pouring hot water directly out of the Keurig and into your brew chamber, it's hot enough to meet Aerobie's recommended method. I never got a good cup the way they recommend you do it. I always did the inverted method with total brew times ranging from 60s to 180s, and varying amounts of pressure (sometimes none, I'd just steep and then let it drain out like a self-contained clever coffee dripper (the plunger would still be useful for cleaning out the "puck").

Play w/the variables, but sour probably means under-extracted. Check grind size, go higher with water temp, and maybe let it steep a bit more.

Alright, it seems that hotter water was a major improvement. I tried making a couple of cups using a kettle, and though I still need to tweak the temperature (it was still a tad bitter), the sourness was gone. Thanks!



JP - I originally used Dunkin Donuts with a fine-drip grind, but I also picked up a cheap can of Folgers to see if it was the coffee or my brewing method.

As for the inverted method, do you have any tips or tricks? I hear it greatly improves the coffee, but I haven't actually tried it yet.

1 - The coffee. Get some fresh-roasted coffee, and grind just before brewing.
2 - As for the inverted method, "teach a man to fish..." and what not http://brewmethods.com/
