Newbie having trouble - needs help!
I'm new to the forum and new to making coffee at home. I just bought a new Breville Oracle semi automatic and can't for the life of me get a 30 ml shot in 30 seconds. The Oracle measures out the dose of the grind and that can't be changed and it auto tamps it (although the tamping pressure can be adjusted) which leaves adjusting the grind as the main way to alter the time it takes to pull the shot. What's happening is the machine pours the 30 mls in about 12 seconds and it doesn't taste good at all. Quite bitter and has a slight burnt taste to it. To get anywhere near a 30 second pull I have to change the grind setting to almost the finest it can go but that seems to make the taste quite bitter. I have increased the tamping pressure but still can't get close to a 30 second pull. To give you an idea of what's happening, the grind settings go from 1 - 45 and the manual says to start at 30. For me to get close to a 30 second pull I had to set the grind setting at only 5! I know nothing about making coffee but this doesn't seem right to me. I bought fresh beans from a roaster in Melbourne and have tried 2 different beans with the same result. I know you guys use mostly fully manual machines and the Oracle is new so not many will have experience with it, but I'm a complete newbie so any advice would be much appreciated.
Morning Steve, welcome to Coffee Snobs.
I cant help you with specifics, however, if you visit this thread http://coffeesnobs.com.au/brewing-eq...-bes980xl.html you will find plenty of information regarding the Oracle, and perhaps even an answer to your questions.
Thanks, Yelta. I found that thread after I posted my question and I have been reading through it. As a starting point I guess I'd like to know what grind setting others are using with their machine. I did manage to get close to 30 mls in 30 seconds this morning but the grind setting was down to 12 and I increased the tamp pressure by 1 level. The result was ok but a bit bitter - maybe due to the fineness of the grind? The puck was quite wet too, but I don't know what this means.
I suggest that you take your discussion to that Oracle thread:
where owners are more likely see it and where Kat Brazier is more likely to respond. Kat is a Breville expert who is a highly experienced barista and trainer. You could refer back to your original post on this page.

Thanks, Barry, I think I'll do that.
Hey Steve, just out of curiosity, what beans are you using? Do you know if it's roasted past second crack or if it's a light roast? Your comments seem to suggest that bitterness is the issue, maybe go for a completely different bean just to be sure?
