Subject: aeropress and acidity levels
 

after a long hiatus from coffee-geekery, i busted back out my bodum press and started tinkering. ultimately i found that the acidity from press coffee was really problematic for me (i had been drinking espresso for years pretty much exclusively up until that point, and never had any problems with the acidity for whatever reason).. so i bought an aeropress. it should be here monday.

is it possible to get a properly extracted cup from the aeropress (which requires deviating from the standard aeropress method, by most accounts) and still retain the benefit of the purported 1/5th less acidity?

thanks,

jesse

Early in the week, I prepared light roasted Kona in the aeropress and got a result that gave me acid indigestion.  It also tasted acidic.  Some of my problem had to do with its strength too.  For the last two days I was using the same bean in a pour over (melitta cone).  No problem with it at all and yesterday it was so good I prepared it twice.

The aeropress is new to me.  For 2 weeks I'd been using it for a dark roasted Colombian which made a smooth cup, so the acid in the Kona took me by surprise when I prepared it the same way.

You *should* be fine as long as you stick to the stock paper filters, but only you will be able to say for sure. Since you've already ordered an Aeropress, I think you might have to answer your own question in this case!

Who knows? Are we talking about actual measured acidity in terms of pH or in the perceived acidity on the palette used in coffee descriptor terms.

Is it the flavour that is the problem with French Press ie acidic/sharp or is it more to do with actual acidity in terms of acid indigestion when drinking French Press?

Frankly somewhat confused over meaning of acidity in this context. Without measuring I have to think there is far more acid in a glass of orange juice than there is in a cup of coffee so have difficulty with the concept that the actual acidity of a cup of coffee would be an issue.

oops. i meant in terms of acid indigestion. should have made that clear. i don't think it's exclusive to french press, either. i had a starbucks drip coffee at work the other day, and it had the same effect.

Different coffees have different natural acid levels. Dark roasting reduces acidity, so a light roast vs a dark roast will give you different acidity levels regardless of the brewing method. I don't know if that affects the 'feel/flavour' of acidity, but it affects the pH.

You probably know this, but water temperature is a key function in aeropress results as higher temperature water brings out the acid in the coffee and you lose the smoothness. When my press was new, I used a candy thermometer to measure water temp in my kettle, so I know what it sounds like/looks like when the water is the right temperature -- 165 F to 175 F (74 C to 80 C). If you let the water boil before making aeropress coffee, you've lost some of the benefits of the method.

Also, how long are you brewing the coffee for? That makes a difference as well.
