Making a second pot of coffee -- do you reuse the grounds?

Gross. I don’t even consider myself a coffee snob (I recall recently posting that I’d stopped grinding my own beans for that very reason) and the very idea is making my tongue curl. Yuk.

Never even thought of reusing coffee grounds, especially with Turkish or Arabic coffee. I have added water multiple times to high-quality tea, though, and do not think that is exceptional.

EGADS!!! Fresh. Grounds. Only.

I bet you people who reuse your coffee grounds are the type of heathens who put beans in your chili and ketchup on your hot dogs.

Get thee behind me Satan!!!

I think this is what it comes down to. How much does one appreciate the actual coffee, or do you just use the coffee as a vehicle for what you really want, i.e., the cream and sugar?

Or do you just make coffee robotically, and don’t care, because your taste buds can’t tell the difference?

I will admit that my mother did this, but that was strictly because money was tight.

Of course, if it is Kope Luwak, you really want to brew that stuff hard, to extract all of the shit out of it.

If a coffee maker brewed 14 cups of coffee instead of 12. Do the last two cups become “gross”?

If too much water is used for the amount of coffee, then yes, what comes through last is inferior. It may be less noticeable in a brewer where everything that comes through is mixed together in a carafe.

If you make good coffee in an espresso machine, it’s much more obvious how bad it tastes if you over-extract.

Reminds me of this exchange from Third Rock from the Sun.

Nina: Dr. Solomon, would you like me to get you a cup of coffee?

Dick: But that coffee’s from yesterday.

Nina: So?

Dick: But I don’t drink day-old coffee.

Nina: Sure you do.

I used to pour more water over the grounds to squeeze out a couple more cups.

It was ok in college and saved money. It got me through late night cram sessions.

I typically made the extra coffee within an hour or two of the original pot. The grounds were still fresh and hadn’t molded.

It is like that. Half of the caffeine and flavors have been leached out. The grounds oxidize, the pH increases, it gets more bitter and the flavors go off. It’s like a cold cup of coffee that’s been sitting around for a while, but more hot and watery.

There is a lot wrong with this analogy.

  • Are you using enough grounds to make 14 cups?

  • Even if using only enough grounds to make 12, first use will make a weaker coffee, not gross.

  • Wait long enough, and the brewed coffee is only good for ice coffee, not hot coffee. Coffee on a warmer degrades rapidly, within 2 hours on the outside it is bad coffee. Even in a thermal no warmer pot, it becomes a nasty bitter brew after 4-6 hours.

Thanks I get it now. I’m not a coffee drinker so I honestly didn’t know.

Cool.

I’m trying to understand the reasoning for this. I assume it’s either laziness or cheapness. There’s definitely a taste penalty.

My father-in-law did this and I quickly learned after the first pot to stop drinking his brew. He was both lazy and cheap. “It tastes just fine, nothing wrong with it”. I assume this is the reason that my wife drank “triple - triple” when we met. She had an epiphany when she learned all coffee doesn’t taste like dishwater.

As far as cheapness goes, I struggle with savings being worthwhile (unless you’re a student?). We buy the big can of Costco Dark Roast Columbian and it works out to less than $0.38/12 cup pot, about $0.03/cup. Reusing old grounds to save $0.03/cup seems silly to me.

BTW - I figured out the price of my brew after my daughter was bugging me to buy a Keurig. I told her the pod price was ridiculous. I had her cost out our existing coffee and said I was willing to buy a Keurig if it was within double the price of our brew. She worked it out and her jaw dropped. The cheapest Keurig pods were at Costco at the time and the were around $0.90/cup vs our $0.03 per cup, about 25x more expensive. That ended the Keurig discussion immediately.

But “unpleasant bitter flavor” is why I drink coffee!

Can you accept the fact, you are an outlier in the data?

I use whole beans, ground in the coffee maker, so no way. I don’t even have ground coffee around. And we make 10 cups, so the grounds would be really gross by the time we’d make more.

We do clean out the basket as soon as it cools down.

Never considered re-using grounds.

Hell no. This is how my brother-in-law makes coffee, and it is the most vile concoction imaginable. He continues adding a little fresh coffee to the old grounds every time he makes a new pot until the filter is too full to add any more. It tastes just as nasty as it sounds.

Re-using grounds is like deliberately cooking a bone-in ribeye to well done. <<shudder>>
