Hi David,

You can grind a bit coarser to increase the flow rate through the filter.  If you feel that your extraction is close to optimum and you don't want the change the grind the next approach would be to turn off the power switch part way through the brew for a short time.  The level in the brew basket can be controlled by modulating the power switch.

I think I was the one who suggested filing the tines to facilitate the dissassembly of the shower.  I still recomend doing that when you first acquire your BCM-4.  That said, if the tines break off it is no big deal.  Gravity will hold the top piece in place.  I have a BCM-4 with all of the tines missing and it works just fine.

EricBNC,

Your memory is spot-on.  My thermos barely holds 22 oz and it was 1 pot = 1 fill.  The ONLY drawback to the Melitta BCM-4 that I encountered was with really fresh-roasted coffee the bloom would push up into the shower head and get the inside oily.  Cleaning required un-snapping the showerhead cap.  Over time, one of the plastic tines would fatigue and break.  One poster noted that the tines can be filed down a bit--I think that is a good idea.

If there is a better way to deal with the bloom and still make a full pot, I would love to know.  Obviously, I will not sacrifice fresh-roasted to avoid the bloom! We are coffeegeeks, after all.

Cheers,
David

Try descaling with vinegar - might get hotter.

 
I chew coffee beans with my teeth while gargling with 195 F water to enjoy coffee. What is this "coffee brewing" device you speak of?

I'd advise against using vinegar for descaling. It can ruin the gaskets and leave an aftertaste.

How did you take the measurement and is the thermopen calibrated?

Two month old Thermopen with NIST papers. Measured directly from pot as it was filling, when first started, midway through, at end of perk..

Still needs to be calibrated in boiling water. I check my Fluke every couple of weeks.

Click here for the correct way to check the temperature. 182f at the point you are measuring sounds about right.

Boiling water test reads 210*, 1% low. So the tests that I did would have been 184*. Close enough accuracy for me. Now to test the BCM-4.. Or not.

The temp of the coffee/water in the pot is not related to the brewing process. What is important is the temp inside the brew basket as it's brewing. But it won't be easy to get your thermapen inside the bcm-4's basket.
