Just finished a medium hot coffee from dunkin donuts (bitb drive thru joe)
Made coffee with some locally roasted beans and it was amazing.

Then out of desperation grabbed some DD from the grocery store and honestly just about as good.

Man, I love me some DD coffee from the shop, but the DD keurig pods I got a few years ago were barftastic

Pro tip for fellow drip makers out there: the instructions always tell you to do way too many scoops of coffee. Honestly unless you’re using a filter with like a gigantic diameter there’s not much difference between 6 and 12 scoops.

I think the second quote explains the first. DD is decent coffee, though.

n00b question that maybe gE engineering and chemistry experts can help me with: why do they always say to use cold water when making coffee? If the water is going to be heated to near-boiling or boiling, why would it matter?

The chemical composition of water changes depending on what you use to heat the water with. Coffee makers have a special heating element that heats the water in just the right way so that chemically it is more ideal to rinse over coffee grounds. It's important to fill the coffee maker with cool water(below 72F) so that the chemical heating process is done correctly and your coffee comes out with the right texture for a solid cup of joe.

Not trying to be dense but how does the chemical composition change? Isn't it H20 the whole time?

I always assumed it was cause hot water has to go through more junk (namely, a water heater) before it gets to the tap. So more opportunity for contamination.

I'm highly skeptical my Mr. Coffee that cost $15 has any kind of special heating element.  It more likely has the cheapest hottest thing they could jam in there without causing many shorts or fires or outright melting through the case.

FWIW, this tread says that cold water has more dissolved O2 in it and that is good, i guess:

A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs shared and unshared repel each other.

The most stable arrangement is the one that puts them farthest apart from each other: a tetrahedron, with the O-H bonds forming two out of the four “legs”. The lone pairs are slightly more repulsive than the bond electrons, so the angle between the O-H bonds is slightly less than the 109° of a perfect tetrahedron, around 104.5°.^2 The heating element in a normal coffee machine keeps this perfect tetrahedron intact while heating the water up. So when the water goes over the coffee grounds with this perfect tetrahedron it chemically can absorb more of the flavor of the coffee grounds.

More to do with hot water just sits there in the tank, but cold water is cycled more often. Stagnate water doesn't taste good.

don't know what that is but it isn't coffee

That's twenty ounces of HFCS in various different flavors, topped with whip cream and then more sugar on top.

Probably pretty healthy.

I ordered some "Alpine Start" instant coffee from Amazon the other day. Not as good as actual brewed coffee but much less terrible than other instant coffee I've tried in the past. Would recommend if you need a coffee-like beverage in a place where you can't make actual coffee.

True life: I don't like coffee. I have tried once a month for the last year and I think can finally say no matter what it is coffeewise I just don't like it.

This is my favorite instant coffee solution. this seems expensive but I can't remember what I used to get it for in Asia

In my opinion, the secret to really enjoying coffee is to use half and half.
