Got one of these, they really produce an exception cold brew but in around 90 seconds, using audio vibration (as best as I understand it). Recommended. Makes a superb summer coffee.

[MEL] Osma Pro Cold Brew Machine
One of the first 1000 machines with a unique serial number and is built like a 8 kg tank.
Was purchased in the initial pre-order but I haven't had much time to play with this so maybe used it 7 times with the single-pass straw since receiving it in March.
Has an anodised black finish on the aluminium chassis which is hard to photograph but marks and dust wipe clean with a towel.
Its claim to fame is is that it uses acoustic cavitation for extraction rather than heat, so there's potential to extract more delicate, fruit-forward flavours without the bitterness from traditional methods.
Comes with all original accessories including the new 8 amp power supply and 58 mm distributor.
Also comes with a new low flow screw which excels at 'coldspresso' for pulling shorter yields as well as the original screw which likely is better with traditional cold brew ratios.
Whichever method, it usually is supposed to extract within 1-2 minutes.
Pesado IMS showerscreen included for more even extraction.

I don't think there's much generally available info out there on the new low flow screw, as it was only introduced around a month ago, but feedback has been game changing and it seems to simplify the process to just a switch on and off without additional preinfusion steps needed. Use and clean up is very simple.
Paid about USD 816 including shipping but I'm looking for $700.
Shipping is possible at extra cost as I have the original box, but given it's weight, I would much prefer for it to picked up in Melbourne CBD.5 Photos
