Been drinking Yirgacheffee all New Years at my mom's place, brewed in a press pot. She roasts here beans in the oven, which makes them more dry than when I roast mine in a frying pan, and I mention this cause maybe it has some effect on the things that follow.
After roasting we grind it (pretty fine grind) and pour it in the press pot, then the boiled water. There is a lot of foam! I mean, shitloads of foam! Usually so much that she has to pour the water over twice because after the foam sinks a bit when she's only poured water over it once the pot's only half full.
Then after more than five minutes waiting it is very, very hard to press down the coffee. Is this correct? My press pots do not behave like this. Four minutes and the coffee goes donw easily. Feels like there's some sort of vacume (sp?) creating the resistance. This a Bodum press, mine are another brand and cheaper. They both make great tasting coffee BTW.
