Anything much over 40 sec will start to taste over extracted/bitter/burnt etc.
Pressure? What does the manual say? Probably 9 bar?
Hi Headache, you are drinking too much or too little coffee??? My Nota pressure gauge starts extraction at 8 bar and builds up to nine bar,the steam is about 1 to 1.2 bar. It takes approx. 5 seconds for coffee to flow after lifting the Brew lever and I aim for a 25 second extraction, total time 30 seconds. There appears to be more error room at the top end, eg 45 seconds is better than 20 sec.At present my partner is drinking 17 gms.of Andys.Indian Elephant Hills through a 18g. Pullman basket and IMS shower screen. I prefer 20g. through a 20/22 gm. Pullman basket and IMS shower screen, and my choice of beans is varied. I only mention the baskets and shower screen because they speed up the pour, previously I was using EP baskets, also good. The supplied larger double basket (14gm?) is OK. I don't care much for single baskets. hope this helps. Chippy
Hi Headake, forgot to mention that a good, maybe not perfect, coffee can be obtained after a 15 min. start up time, provided I flush a little Hot water through the Brew head first. Chippy

i would only use a double group as i like strong coffee
if tamping i get around 8 to 9bar i am tamping hard enough?
i think i had short poured a lot as seems to have a lot of liquid very quick normally 15 to 20sec
i havent weighted my grind yet by your post i should aim for 14 to 20g? for a double shot?
Hi Headache, I don't think you got my warped sense of humor, notice the spelling of your name in my first and second posts, hence the dig about too much or too little coffee. No serious offence meant. Firstly Tamping doesn't make all that much difference IMO, as long as you are consistent. If your extractions run at 8-9 bar your Nota is probably set up OK. Secondly a double basket doesn't mean you are making strong coffee, 25 gram extractions into a 500 ml mug is not as strong as 14 gms into a 120 ml cup. Re. extraction its all about weight of beans, time of extraction and amount extracted. I extract 30-35 gms of Coffee in 30 sec. total time or 25 seconds extraction time, my extraction ratio is high 1.5 to 1 (33gms extracted coffee to 22gms of beans). I think 2-1 is more usual. Your 15 seconds is a bit quick, try grinding a little finer till you get a 30 second extraction. Try the coffees as you go and you will find the sweet spot for you. good luck Chippy
all good no offence ha ha...
