Topic: Bunn home coffee maker (19 msgs / 489 lines)
1) From: Wesley Simon
Hi everyone,
I know there are some Bunn people on this list...
My girlfriend has a Bunn coffee maker.  I haven't looked up the model numbe=
yet.  I ground up 84 grams of coffee, enough for my 12 cup pot,
 to take over to her house.  Her pot brews 10 cups, not 12.  I put probably
2/3 of the coffee in the basket, less than I would have put in my pot.  The
thing overflowed out of the basket.  It's as if the water comes out of the
shower head (whatever you call it) too fast.  My grind was not too fine: SM=
set on drip.
Are there generally adjustments for the Bunn home coffee makers?  If so,
what would you recommend adjusting?

Hi Wes,
Before I returned my brand new Bunn BT10-B last week, here's how I coped
with the problem.
1. The problem- seems to be hot water hits the fresh roasted coffee, the
grounds "bloom" (expand a bunch), and then the Bunn adds lots more water to
make it special...
2. My Solution-
  a. pour all the water in the reservoir, leave the door up.  Put the
grounds in the basket, lock and load, put the carafe under...
  b. close the reservoir door for 15 seconds, then reopen it.  This allows
4-6oz of water to hit the grounds, cause the bloom, soak in, and then drip
  c. after 1 minute, close the door again, for 15 seconds, then reopen...
Same reason
  d. after 1 minute, close the door again and let the water all go by.
I find the coffee richer, and not all over my counter...
I returned the brewer within the 30 day guarantee period because I couldn't
find a permanent filter, and hated the paper filters stealing all the
luscious oils from the brew...

Contact Bunn and they will send you a part to 'fix that'.

I picked up a couple of those (one is at home and one is in the office) 
when Target closed out the low end model a couple of years ago. Because 
the brewing time is so short here seems to be a fine line between 
getting enough coffee in the filter to produce a decent cup of coffee 
and getting so much in that it overflows.
I don't use the one at home much and the one at the office uses whatever 
coffee is handy, ground to whatever fineness is deemed appropriate by 
whoever makes that particular pot of coffee, but:
1. It seems to be worse with fresher coffee that blooms more.
2. Its never happened to me and I tend to use a larger grind than most 
of my coworkers.
So you could use a larger grind, older coffee or start dating a women 
with a French press - I'd start with a larger grind :-)
BTW, there is a recall out for a bunch of the home Bunn drip units.

A few years ago I found that the older type Bunn carafe allowed a Melitta#6 
filter to sit on top of it perfectly, and the whole thing fit very nicely 
under the showerhead.
See here:http://www.homeroaster.com/setup.htmlThe cone allowed me to use a finer grind, more coffee and better filters, as 
well as solving the blooming problem with the shallower hopper of the 
standard Bunn.  I don't care much for the Bunn, but it improved the coffee 
significantly in my opinion.

Looking at the Bunn website, it's a model GR-10.
So, does this thing need a "flow restrictor?"

Your grinder contributes directly to the performance of your Bunn. I  
have 3 separate grinders. A Black & Decker, a Cuisinart, and a Bunn.  
The Bunn works the best, the B&D is the absolute worst. All three are  
burr grinders, and these can produce fine flour-like by-product with  
your grind. Some more than others
The B&D will stop of my filter so that the water level rises in the  
basket and makes contact with the shower head and top. The Cuisinart  
does a fair enough job but is also the less messy of the bunch. I  
think that the Bunn grinder is the best grinder for a Bunn brewer  
because it is incapable of producing a fine grind. It says in the  
manual not to use it for espresso because it's not designed or built  
to even produce that find of a grind. Of course there will be some  
inevitable powder that clings, but the burrs don't get close enough  
to make any consistent fine grind like the others can.
For my French Press I use the Bunn grinder. For my Bunn Brewer I use  
the Cuisineart - less messy, used more often. Black & Decker collects

I have had the same issue.. I think I will try the Melitta #6 trick, as my
Bunn is the same pictured on Ed's site (the older model with the more
bubble-shaped carafe).  Something that I've also noticed that helped was
using Bunn brand filters instead of an off brand basket filter.. I'm not
exactly sure why this is, although it does seem that the Bunn filters are a
more precise fit for the basket.

I used a Bunn coffeemaker for several years and found the following:
1) Bunn has a lower flow head, actually intended for decaf coffee, that they will send you free of charge. I didn't need it, but it is available.
2) Always use Bunn brand coffee filters. They really do make a difference.
3) With home roast, you really do need a good grinder. A grind that causes powder in the grounds will clog the filter and it will overflow. I kept adjusting the grind in my Rocky until the grounds came really close to the top of the filter without overflowing.
4) I always let the coffee rest for 2 or 3 days before brewing. There is a lot less bloom that way.
I have a fairly new Bunn in the garage but have been using a KitchenAid Pro-Line coffeemaker for 8 or nine months now and I like it very much. Great, hot, coffee. I still use Bunn filters.
Melitta, of Salton, made a Bunn type coffeemaker that uses the Melitta cone filters that looked very interesting. I couldn't find much information about the brewer or the water temperature so I didn't go there. There are some available but I believe it has been discontinued.
Hope this helps,

Her filters are probably not Bunn.  There seemed to be almost an inch
between the top of the filter and the top of the basket.  Perhaps the Bunn
filters are deeper.
I use a SM+, the grind should not contribute to the problem.
The coffee in question rested for approximately 1 week prior to finding
itself in the Bunn, the bloom shouldn't be much of an issue.
I have to be careful messing with a woman's appliances.  They can be funny
about such things...

Follow up:
I tried the Bunn coffee filters, it was better but still the grounds seemed
to crawl up and over the edge of the filter.  I ordered the low-flow head
from their website and it now works great: no overflowing the basket
I've started leaving her several pots worth of ground up coffee.  I may try
to get her to use a whirly blade grinder so that I can simply provide her
with beans...

The first time I used the Bunn at church with my HomeRoasted coffee, I
ran into the same thing. I did two things that seemed to help:
1. measure enough H2O (1 -2 cups) and make cowboy coffee -- coffee
added to the water in a separate pot. This was to let the coffee bloom
in the pot, and not the Bunn. I them transferred the coffee to the
basket and filled the BUnn with the remaining clean water to finish
2. I almost always pre-wet any paper filter I use. Melitta #2, or
Bunn, or other 4-cups brewer. This seems to help keep the coffee from
soaking into the filters since they are already 'full'. This may be a
placebo, but maybe not.
I'll have to look into the Flow Restrictor part, sounds like it would
be a great alternative.

They sent me the flow restrictor for free based on the date code which I
believe was still in the 3 year warranty.

In addition to the flow restrictor, I found that a plastic sink strainer

in the disposal) placed on top of the grinds really cut down on the

I've always wondered how much time this low-flow head increased the  
brew time by. Have you ever timed it for a full pot?

I haven't timed it.  I'd guess that it's no longer than 5 minutes.
