French Press

[Garbandz]

In my experience,bitterness derives from three sources:
1.over roasted coffee
2.water too hot
3.coffee left on the heat too long

I have the french press,a drip machine,and an espresso,and I roast my own coffee.
The drip can over cook coffee by being left on for extended periods.
The french roast will make bitter coffee if the water is too hot or the roast is too dark(burnt).
The espresso will be bitter if the roast is too dark.
Since I have been roasting my own (3+ years) there have been no problems.

Pektel,brightness in a cup is evidence of city roast,combined with freshness in the beans.I get a blueberry flavor from Yirgacheffe and Sidamo when I roast to city level.

Some beans can produce a Meyer lemon or grapefruit taste, orange zest,plums,lots of things.
Darker (city+ to full city) roasts can produce caramel,cocoa,graham cracker,cake or cookie type flavors.
You can also adjust coffee flavor profiles by changing the grind,I use an espresso grind in my drip unit and get a deeper extraction and more espresso-like cup.
Use a french press grind and get an almost delicate taste from the drip unit.
