Subject: Espresso through Keurig machine?
 

I realize that the Keurig machines have a very weak pump, certainly not enough to press through fine ground espresso beans in a manner in which actual espresso machines accomplish.

My question though is, if I grind up my own espresso beans very fine and put them in the reusable k cup filter, can a Keurig produce a strong enough extract through the "small" cup option to resemble the espresso flavor at all? Could I use it in blended iced drinks? Would it taste acceptable?

Not really, no.  Espresso is produced by the puck of grounds resisting the pressure of the pump/water.   The reusable K-cups don't have the same geometry as an espresso portafilter, with the filters at least partially on the side of the cup.  I think commercial K-cups already use very fine ground coffee in order to get acceptable strength in the short brew time they use.  With the reusable K-cups you can use a bit more coffee, but you aren't going to get any significant resistance to flow or pressure build up.  What you will get would be a fairly strong brewed coffee, which can make perfectly acceptable iced coffee.  You don't need espresso to make iced coffees.

Thanks for the reply! I figured about as much. I'm relatively new to iced coffees. I'm assuming that the quality of the bean matters very little, if at all in an iced beverage. I'll probably just have some Folgers on standby solely for that purpose.

Bean quality still matters - particularly since most cheap and dark roasted beans don't have much flavor beyond bitter and burnt astringency.  Get some Central or South American beans noted for chocolate/nutty type flavors and sweetness and try those, or maybe an earthy Indonesian for contrast to sweet ingredients.  Very acidic fruity coffees can be a bad idea, as they can curdle milk or cream used in blended drinks if used while very fresh from roasting.  The taste profile of beans changes with serving temperature, but not the desire for quality.

Good to know! I usually prefer an acidic Guatemalan dark roast. I'll try it out with what I have and purchase a medium sweet roast for next time.

Nope.  Even the Vue can't.

Try it and see.  One person's acceptable isn't another's.  I wouldn't bother but you might like it.

The quality of bean always matters.

I tried it once out of curiosity, since I had a "My K-Cup" filter.

My K-Cup machine puked a bunch of water, made some weird noises and make made a small amount of really terrible tasting coffee
that reminded me a little bit of turkish coffee that wasn't quite made right.  

Even though I don't think I hurt anything, I don't recommend trying this. I spent probably the better part of 15 minutes cleaning up.
