#52Robusta is doing just fine... https://www.anthropocenemagazine.org/2024/08/coffee-is-threa...
If, as the article says, you like instant coffee, then great.
There's also the possibility of hybridizing Robusta and Arabica to get the best traits of both. A few hybrid varieties, such as Catimor, have existed on the market for a while. AFAIK Catimor has some of the hardiness of its parent Robusta.
As always, you'll have the best experience if you buy whole beans and grind them yourself (or at least find a supermarket that lets you grind beans fresh). No instant coffee that currently exists will be able to compete with that.

As a daily coffee drinker I wouldn't mind less caffeine in coffee. I drink coffee for its flavour (and have tried dozens of different coffees from many different roasters). I have tried some decafs but they just taste different and generally much flatter. They also behave very strangely in my espresso machine, requiring a much finer grind to sustain brewing pressure. From my limited understanding of decaf processes,…
The biggest reason decaf brews, tastes, and grinds so different is the processing essentially causes the beans to expands (so you can extract the caffeine out of the center of the very dense, green coffee) and then you need to dehydrate them back to the proper moisture content for roasting. You take a green coffee that is previously extremely dense and non-porous, and make it much much more porous. This leads to roas…

Yes you can. See Patagonian Toothfish -> Chilean Seabass.
Or Chinese Gooseberry -> Kiwi Fruit.

Eugenioides is sweet in a way that no other coffee I ever had is sweet. You sometimes see "sweet" as an axis of flavor of coffee, or as a tasting note on a bag of fancy beans; but eugenioides is very different. It's _the_ dominant note in that cup, and it is much less fruity or floral, it's just... sweet. You taste the sweetness, and then the rest of the "typical" coffee notes come in the background, but much less pr…
When you say sweet, is that because the coffee has more sugar, or are there just other compounds? I guess what I’m asking is what’s the difference between what you’re describing and making a regular good cup of coffee and adding a teaspoon of sugar?
I don't think brewed coffee contains any meaningful amounts of sugar?
Coffee (filter/brewed, not espresso) is ~98.5% water by weight, even if the Eugenioides species has more sugar in the beans than Arabica (it might! literally no idea here) — if the difference would be "just" down to the sugar levels, I don't think it would be noticeable at the dilution levels we're talking about.
The difference in the natural sweetness vs adding sugar is an interesting question, honestly!
Sugar is usually added to coffee to hide/mask/round out the bitterness; whether naturally occurring or from overly developed roast. But it also masks/drowns out other notes, too. You'll get less bitterness, but less of the acidity, the floralness, of all the other subtleties that can make coffee great — you'll get _sugar_ sweetness (and it's a very different kind of sweetness than coffee can naturally have!), and less of everything else.
Eugenioides is different because it just doesn't have that baseline note of bitter/hashness _at all_, and it's naturally pretty sweet.
Instead of sugar, I think the "magic berries" (I never tried!) that mess with your bitterness perception might work better? I'm actually now curious to try it out...

Some areas will get drier, others (like the Sahara and Sahale for example) have and will get wetter.

Huh. As an avid home coffee roaster, this is interesting to learn. I find that decaf also really struggles to “crack” when roasting, and emits way less smoke. I guess that’s because there’s perhaps nothing left to really crack anymore?

So you're not denying climate change, just the effects of it. I'm not sure that's any better. We call it climate change because warmer weather produces higher variance in weather patterns--you're adding entropy into the system. Overall warmer, but more rain (and mud/rockslides), more wind, more lightning, etc etc.
As I read it, he's not denying the effects either. He's just saying that not everything bad that happens wrt climate and weather is due to "climate change". Sometimes, it's just variations, which have always happened.
A recent example is the CA fires, there is zero evidence linking them to climate change - they did a study and found no effect - which of course was reported as "climate change to blame".

#60Maybe the answer is for someone to work on boosting natural caffeine levels in yaupon holly tea. It grows wild all over the SE US and can withstand multi-year drought or regular floods though it does best in a situation where it gets regular rainfall. You may have some in your own yard used as a hedge plant. I have several large trees on my place. It spreads underground by suckers and will take over an area if you do…
