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

On those occasions when you make a second pot (or half pot) of coffee, do you dump fresh grounds on top of the ones from the first pot, or do you start fresh?

If I’m making a full pot, it’s probably 50-50. But if I’m only making a half pot, I will almost always dump more on top of the grounds from the previous pot.

Start fresh. The very thought of reusing grounds makes me :eek:

2007 thread, for reference.

Sounds disgusting. Admittedly, I rarely put shit in my coffee, so how it tastes on its own is very important to me.

Gross, no. Always start fresh. Coffee grounds are used up the first time :slight_smile: For one thing I use about 3/4 of the basked with fresh, so there would not be room for used. I have a Tassimo at work, and everyone once in awhile an old pod gets mixed in. What comes out is slightly yellow non-coffee.

What’s wrong with leaving the old grounds in the filter? It’s not like the addition of hot water spoiled them or anything. Of course you add fresh grounds, but re-using the old grounds adds a little extra ooomph.

I am not a fusspot about my coffee. Or a coffeepot about my fuss.

Never. Coffee gets new grounds every time. If I need to stretch my supply, I’ll just make less.

Moving thread from IMHO to Cafe Society.

The different characteristics of coffee come out at different points of the extraction process. The quickest to come out are acids and sugars, then oils, and last the more bitter tannins. By leaving the old grounds in there, you aren’t adding more ooomph, you are adding more of the unpleasant bitter flavors without anything else to balance them.

What is this communism? Hell no we don’t re-use grounds.

No, I don’t reuse the grounds. I like coffee to taste like coffee.

I don’t reuse grounds.

My ancestors didn’t spend a million years evolving from the apes for nothing.

If I want to make another full pot of coffee, and only have enough grounds for a 1/2 pot, then I just keep the old grounds in there and dump the new on top. Otherwise, I don’t reuse the old grounds.

Grind the beans, put in cold, purified water, make the coffee, dump the grounds, drink the coffee.
Repeat as needed.

If I am making a second pot right after the first, I add 50% new to the old and brew away. If we’re talking the next day I start all fresh.

I do the same basic thing making tea in my Mr Coffee.

Assuming coffee’s like tea, most of the caffeine is going to be extracted in the initial brewing. So reusing them doesn’t really accomplish much- you can’t get a good pot of coffee out of the leftover grounds, and what you do end up with is going to be distinctly low octane.

This was my immediate thought. Really sounds nasty to me.

My friend does this. It’s ok. Her coffee’s not good to start with. She drinks so much black coffee I think she’s burned off all her taste buds.

I dump out the old grounds and put fresh grounds in the basket.

On the 2nd pot right after the first, I DO throw the new grounds on top and reuse the filter, but I use the normal amount. It always tastes fine to me.
