  • 20 Second Peak at a Guatemalan Coffee Wet Mill

    Posted on February 20, 2014 by Venia Coffee Roasters | Keith

    Our friends posted this video of their coffee at a wet mill in Guatemala.

    There are several methods for processing coffee, one of our favorites is wet process (aka washed, fully washed).  Shortly after being picked by hand, coffee cherries are taken to the mill where they are first sorted in water tanks, then sent through the pulper, which is what is shown here. The pulper removes the skin and much of the fruit from the coffee bean.  After this, the coffee is then sent to fermentation tanks where they will stay for about 24-48 hours.

    In the video you can see the red coffee cherries going into the mill.  In the last few seconds of the video you can watch the de-pulped coffee beans exiting the mill.  At this point they are whitish/light yellow in color and still covered in a sticky mucilage that is removed in the fermentation tanks.

  • How to Make Coffee Using a Chemex Coffee Maker

    Posted on February 10, 2014 by Venia Coffee Roasters | Keith


    Ah, the Chemex coffee maker.  As a chemestry nerd myself, I have always held a special place in my heart for my Chemex.  Invented in 1941 by chemist Peter J. Schlumbohm, Ph.D., the Chemex is one of the most capable brewing devices we know of for bringing out the best in our coffees.


    Chemex Inventor Peter  Schlumbohm


    Originally, Doctor Schlumbohm's design was made in two parts, a modified glass filtering funnel and a modified Erlenmeyer flask.  Later, the two were combined and the beautiful wooden handle added and became the Chemex we know today.

    Many accolades have been bestowed upon the Chemex over the years and is in the permanent collections of the Museum of Modern Art in New York, the Philadelphia Museum, the Corning Museum, and the Smithsonian.  As impressive as these honors are, perhaps the most impressive is the resurgence of use among the nations top coffee bars.

    All of this has resulted in a bit of mystique over the Chemex.  Reality is that they are remarkably easy to use.  The filter paper used is thicker than standard drip coffee filters and produces a very clean and clear cup of coffee.  Newer metal "Kone" filters by Able are also available and allow more oils through and produce a cup with more body.

  • Mazzer Mini E Grinder Mod | Super Jolly Burr Set

    Posted on February 5, 2014 by Venia Coffee Roasters | Keith


    If you have been stung by the coffee bug, chances are you are constantly looking for ways to improve the brewing process to get the most out of every bean.  Just about 20 years ago I was a poor college student and I bought my first air popcorn popper from the local Goodwill and started the adventure of learning how to roast coffee.  It was only a few weeks later that I was trying to modify the air flow to achieve a more even roast.

    Over the years, there are few coffee gadgets that have made their way to my kitchen counter that I have not tinkered with to some extent, some with quite successful results and some not so much (before doserless espresso grinders were popular I cut the plastic doser off my first burr grinder with a dremel tool...that poor little Gaggia...).

    Perhaps one of the most frequent questions I have been asked regarding grinders lately is whether or not the Mazzer Mini Electronic espresso grinder burrs can be replaced with Mazzer Super Jolly burrs (AKA Mazzer Normale).  On paper, it would seem that they would work, same dimensions, same 3-hole screw pattern.  The only difference is the more aggressive burr design.  Having heard of these being successfully installed on Mini-E's, we thought we would give it a go.  We have been very impressed with the results.

    Before swapping out the stock 189D burrs on the Mini-E, we ran several 17g doses of our Uganda Mt. Elgon Natural coffee that was dialed in for an espresso grind.  Grind time was between 20-22 seconds.  After the swap with Super Jolly 33M burrs, the same 17g dose dialed in for espresso took about 13 seconds, a impressive improvement.

    We have had about a week of use on these burrs since filming for the video and we are nothing but impressed.  Grind quality is vastly improved and extraction is routinely more uniform (viewed using La Marzocco Advanced 17g basket in a bottomless portafilter).  Cup quality is also noticeably improved with much more clarity.

    A few points to note before venturing down the path of this mod.  The Mini-E burr set is specifically designed to be less aggressive than the Supper Jolly burr set.  This is likely because the Mini-E has a lighter duty 250W motor while newer Super Jolly's have a larger 350W motor with a bigger duty cycle.  While we haven't noticed or heard any signs that the Mini-E motor is being pushed beyond its capacity, we cannot recommend this Mod for anything beyond light-duty use.  I also feel the need to note, that older Super Jolly grinders have 250W motors and have run for years with heavy and frequent use, but swapping the stock 189D Mini-E burr set with the 33M Super Jolly burr set will void any warranty, so M.A.Y.O.R. (Mod At Your Own Risk).
