[Homeroast] Vacuum Pot Help!!

Doug,

This says everything I have experienced and can say as well except I use a
Cona Rod. I just use a spatula to keep the rod down when the rise finishes.
I don't add grinds until water has fully risen.

Hi Dennis,

I'm late (very late) to this conversation, so forgive me if this is no
longer an issue.

The vacuum pot should be giving you perfect cup, very clean, in fact too
clean for some people.

'Sour' isn't a flavor that I associate with vacpots, and I can't think of
any brewing variant (too hot, too cold, too fast, too slow, too coarse, too
fine, etc.) that would trigger that. Certainly not grind, and also certainly
not water that's too cold (which tends to highlight sweetness, actually).

'Bitter,' maybe, if the water's too hot or if you get drawdown delays, but
not 'sour.'

The sour flavor you're getting is almost certainly from the cloth filter.
One way to confirm that would be to simply replace the one you're using with
a new one and see if the flavors change.

You should be able to brew at any grind level you like.  The flavor changes
you get from change of grind are more or less as you'd expect them (muddy at
Turkish, broader and rounder at coarse). You can and should be grinding for
flavor anyway, not as a means for correcting mechanical problems.

Your drawdown times of 1-1/2 to 2 minutes are perfect, but I'd expect that
with the cloth filters, which behave quite consistently from pot to pot.

I'm a devoted fan of the glass rod. I have the Yama 8-cup and Yama 5-cup
pots, and I use a Cory rod (no longer manufactured and has to be bought
used). The Cona rod can be made to work, but is simply not as effective.

I've been making vacuum pot coffee with the glass rod filter every day for
nearly three years now, and I love it.  There is a little extra skill
required to get the glass rod to work (it took me the better part of a year
to work it out!), but not much. Once mastered, you can brew any grind level
and roast level you like without restriction.

If you go glass rod, you simply MUST add the 5-second burst of heat just
before taking the pot off the heat. If you don't, you'll almost certainly
get inconsistent drawdown times and, potentially, stalls.  This is
especially true if you're grinding coarse (30 on the Virtuoso is pretty
coarse) and/or roasting dark.  But if you do apply the burst, you should
have the same 1-1/2 to 2 minute drawdowns as you're already getting with the
cloth filter.

Final note: Like Bob (see above), I also replaced one piece without
replacing the other, and discovered that the new match is a little
problematic.  There now is a lot more drama as the water finishes rising
into the funnel. The rod gets blown out of position, a condition that cherry
complained about a few months back and that led her away from the Yamas to
the Cona tabletop.  To prevent this, I now have to be very careful to have
the heat way down low to finish the rise. It's otherwise not a biggie. So
the match between funnels and pots can be less than perfect from
manufacturing lot to manufacturing lot.

But even with the finickier replacement, I'm still totally rapt with the
coffee I'm getting from this brewing method.

Doug
