Recycling: Please come cash in our bottles & cans!

by Patrik D'haeseleer

Hi all, I just threw several dozen bottles and cans in the recycling bins. If someone wants to pick them out and cash them in, feel free! There's a big blue recycling bin in CCL that I originally bought because the Fermentation Station said they wanted more bottles. But inevitably, I'm the one who winds up having to empty and clean that bin every week anyway. So - IT'S FREE SEASON ON EVERYTHING WITH A CA REFUND VALUE! If the Fermentation station empties the bin in CCL, that's great. If … [View More]

Kombucha starter

by Patrik D'haeseleer

Hi all, Jenny (CC'd) would love a thin slice of Kombucha starter to make a Xmas card out of it. Do you guys have some to spare? Will anyone be around this weekend? Otherwise she may drop by your meeting on Monday. Patrik

Event in CCL tonight at 7pm

by Patrik D'haeseleer

Hi Fermentation peeps, Just wanted to give you a heads-up that we will be having an event in CCL this evening at 7pm. So it would be really appreciated if the fermentation meetup could wrap up a little early today, so we can start setting up the space around 6:30. We'll be hosting a vegan cheese & beer tasting for some of our IndieGogo donors and members of the Real Vegan Cheese team. I would prefer not to have random walk-ins during the event, but I expect there may be some leftover beer … [View More]

Does Fermentation Station need a steady stream of beer bottles?

by Patrik D'haeseleer

Hi all! How are you guys doing on collecting beer bottles - should we save all beer bottles generated at the Omni for you? Or just throw them in recycling? I'm planning to go buy some trash and recycling bins for Counter Culture Labs - just wondering whether I should buy a separate one just for beer bottles, so we can save them up for you. If you already have a container where you're collecting bottles, just let us know and we'll tell people to deposit bottles there (just don't expect them … [View More]to clean the bottles first, because that ain't never going to happen...)

Need to move Kombucha cultures in CCL, due to construction!

by Patrik D'haeseleer

Hi lovely fermentation people, In case you hadn't heard this yet, the landlord will have some people working on the skylights in Counter Culture Labs on Tuesday. This means that all valuable equipment and breakables (like your kombucha cultures!) need to move away from underneath the skylights, so they don't get destroyed by falling debris- preferably by this evening! Furniture that can take a dent or two - like filing cabinets and desks - can presumably stay in place. I believe the workers … [View More]

meeting later today 9/1 5pm

by Stan Osborne

Last Monday after the meeting one of the locking file cabinets was moved against the wall and the brews were placed on top. On Monday this cabinet was reconditioned with the help of Sean. Four additional keys were made with one given to Sean. Ihave the master key and three copies.. Labels were placed on some of the drawers. Food Not Bombs asked for use of one drawer. One drawer remains to be allocated. There is at least one more locking cabinet that needs reconditioning and keys. Two … [View More]

New kombucha batches started at Noisebridge

by Rikke Rasmussen

As of today, we've rebooted kombucha production at Noisebridge: two 15L batches of oolong tea kombucha (of Three Stone Hearth origin) have been started by Alex, Frank and myself, and are now sitting in white buckets on top of the lockers by the East Wall. We hope they'll be ready to serve up in time for the big opening on the 15th - fingers crossed! I'll post this to the Noisebridge kombucha wiki sometime tomorrow. /Rikke On Aug 12, 2014 10:52 AM, "Francisco Jimenez" <francisco(a)… [View More]tucanvinegars.com> wrote: > Hi all, > > For me it was a very interesting experience making cambucha.
