Brewing coffee on shabbos?

[youG]

I ate at someone's house and they served fresh brewed coffee after the meal. He said he used a kli shlishi and there's no problem.
 I never thought of this.
What's your take? Muter? Asser?
( do we say ain bishul achar bishul? Or is coffee considered afiya- baking so may be problematic?)

A friend of mine mentioned to me that starbucks VIA is the same problem because it is considered micro brew opposed to instant. Meaning the grounds need to be cooked unlike instant where they dissolve. What's your take??

And what about straining?

What exactly did they do?

+1, I'm not quite understanding what they did. If the coffee "brewing" happened with no contact to a heat source and the water was a kli shlishi, then it doesn't matter what kinda coffee or whether there was or wan't bishul/afiya before. That's what I understand/remember.

"brewed" coffee from concentrate? Sounds like a hoax...

They set up filter in holder on top of a cup and poured water into it.

And why would that be allowed?

Seems like there would be no problem of bishul, but how is it not borer?

The heter extends to everything

[thaber]

The Kli Shlishi heter works for even tea bags, for sure coffee. But Borer would be an issue. However an automatic coffee maker on a timer would be much easier to be matir. Unless you have a problem with timers, its hard to find an issue.

Is this the place to ask HALACHA questions?

If they set up the filter with the coffee inside it on Erev Shabbos, and it was just a matter of pouring water (Kli Shlishi) over it on Shabbos, it seems like it could be fine - See Shmiras Shabbos (old) 3:58, and sources in footnote 174. [Although probably advisable to inform guests exactly what is going on so that no one draws any wrong conclusions.]
If they did it on Shabbos, it escapes me how this could be Muttar.
