pour time

Post by **michael** » Mon May 21, 2007 2:28 pm

when i fill the double basket with 15 or so grams of coffee and tamp well, i still only get about a 10 - 15 second pour. i am grinding my beans with a mini mazzer electronic set a little bit finer than the factory setting. i have a brand new VII and haven't changed any of the settings or the screen configuration. so far i have used sant eustachio beans and the beans i received from chris coffee with the machine. i have lots of crema and no channeling. any ideas on how to get the perfect 25 second pour

I grind WAY finer than the factory setting on my Mazzer.

What volume are you drawing in your 10 seconds? If the volume is low you may also need to increase the volume programmed on the button.

At 10 seconds are you getting blonding? (in other words what stops you at 10 seconds)

in the 10 to 15 seconds, i probably get 2 oz or very close to it; what stops me at the 10 - 15 seconds is the programmed dose on the double button of the machine ends; this is the setting as it came from the store; i havent reset it

I go about 7 ticks finer, I'll post again when I confirm this but I get about 1.5 oz (or less) in 25 seconds. It mousetails very fine into the cup, remember I'm pulling ristrettos.

what temperature are you using for the malabar gold blend

That's pretty much what I do.
For island coffees I roast a little lighter but I brew at 95. The darker roasts I brew at 93, some of the Centrals taste great at 94.

So do I on my Mini. This was not the case with my Isomac Tea. I'm grinding finer for longer (duration) and shorter (volume) shots. I also notice (in the 6 mos I've had the VivII) that freshness matters a lot. So I'm much more careful about my batch sizes when roasting. Seems to be a point after +/- 10-12 days that the shots want to flow much quicker. In some respects the Tea was more forgiving in these respects, although the shot quality declined--shots just looked better. Advice? Avoid very freshly roasted under 36 hours or over 9-10 days coffee. See if it makes a difference.

Martin,
I think it's the pre-infusion thingy we talked about a while back. It makes a shot look better, doesn't mean it'll taste better. I get this on my Anita, old beans still pour nicely but they don't taste "nicely".
You're right about the Vivaldi, it's a really sensitive machine with a "hair trigger".
