Posted Fri Jul 23, 2010, 2:49pm Subject: Can We Make a Commercial Cold Brewer?
I saw the Toddy Commercial brewer and I wondered if we could make one. I would like something, if he is interested, for Marcel at his coffeeshop, or if he isn't, there are other ways this can be put to use. He is from a different country, so I will let him communicate what regulations and standards are necessary, if any.
Has anyone seen these or know how to make one?
Thanks for your time, and hope it helps.

I learned about this method originally from my mother. Parents of her childhood friends would prepare this using canned preground coffee - a full (big!) can at a time.
From what I understood, they prepared this right in the can. Open the can, open the cold water faucet, and allow the water to slowly fill the can, soaking all the coffee. When it's full, put the plastic lid back on it. Wait a day.
When it was ready to drain, I believe they poked a hole in the bottom of the can (with an ice pick, possibly a can opener or a nail), and let the extract slowly drip out into a collection vessel - a jar, or similar.
As far as I can tell, yes - that's it. A cloth bag in a bucket gets the job done. If you can lift the bag out of the bucket and let it drip into the bucket, you may be able to get more coffee out. Spout is convenient, but you could also dip out the coffee with a ladle, or decant into a pitcher.
(Other brainstormers should definitely jump in here - my expertise level is just "I like coffee.")
