I have recently gone from a 6910 to a BDB, the flavor difference is substantial, you can get the same flavor consistently with ease dramatically more so than the 6910, the mess and noise is much lower and if you get the matched grinder noise and mess is much improved from that area as well (the grinder is a huge step up from the 6910 one), cleaning is easier, etc.
Overall it is just more refined. We have 3 to 400 cups through ours so far and it superb.
After using the 6910 you will find a single boiler annoying for milk drinks especially multiple of them, and if there is no PID consistency will suffer.
Guide for Silvia to make one coffee by a fellow coffee snob spg1960, add a cool down period to brew again.
Sure, this is a basic guide I typed up for my wife to use when i`m not around. She has watched me use the Silvia, but needed a bit of a reminder of sequence and timing. its quite brief, but you will get the idea of what i mean i`m sure. happy to clarify anything that isnt clear, cheers
make sure machine is warmed up and has been on at least 30 mins
Select cups you need.
1. Hit the brew switch and run hot water into the cups to warm them up.
Run the water until the heating light comes on.
( Leave the hot water in the cups until just before you make the coffee )
2. Grind the coffee into the portafilter and tamp ready for the shot. Grind enough coffee into the portafilter to fill it evenly. Tamp quite hard, give the filter a little tap with the handle end of the tamper, give it a turn of the tamper to have a nice smooth finish
Wait until the heating light goes out. Use the timer and time 30 secs after that.
Prepare the milk jug ready for frothing and empty the hot water from the cups while you're waiting !
3. Put a spare jug or cup under the grouphead and hit the brew switch for 3 or 4 secs.
(this is to bleed off a little heat and not burn the coffee)
4. Go time ! Put the handle in the grouphead and make the coffee !!
5. Use the timer to time your shot. 30 secs should give you a good shot.
Mmmmm nice work
Ok now for the milk.
1. Take the portafilter out and get rid of the old coffee.
run the brew switch for about 10 secs, this cleans the machine and also helps build up heat for the steam.
2. Hit the steam switch. wait at least 1 min for the pressure and steam to build up.
( I do a little cleaning up in this time)
3. put an empty jug under the steam wand and bleed off the water until you get some nice dry steam coming through.
Empty the jug and wait another couple of secs for the steam to be good.
4. Froth the milk !!
5. Pour your froth... don't forget, foam always pours in a steady stream.
Drink your cafe quality coffee !! Think of how nice your husband is.
PS, if you are doing another coffee straight away, put an empty jug under the grouphead and hit the brew switch for a good 10 secs. This gets rid of the built up steam.
Now start at step one !
