Brewing

London Hackspace Brewing

A successful inaugural brewing session was held at the new Hackspace on the 2013_August_Open_Day.

Brewing as a "project" is being driven by Det, helped by Ross, overseen by Russ with equipment borrowed from B3cft.

Anyone can participate, even if you've had no experience before, there's always cleaning to be done. :)

Contacts:

A public Google sub-group exists for planning brewdays, discussing recipes and the like.

Other topics that affect the Space as a whole should be done on the main mailing list.

IRC: #london-hack-space-brewing on Freenode

Planned Brewdays:

Date	Time	Organiser(s)	Beer
08/12/13	1000hrs	Russ	London Old Ale

Location:

Brewing will take place outside on or in front of the loading dock for various reasons, namely ventilation and easy access to running water.

As there's no fixed hose fitting that we've found, we'll be clamping a hose on to the bathroom tap just inside the roller door. This is used for the immersion chiller whilst cooling the wort. Thankfully there's also a drain below the loading dock.

Equipment

B3cft has kindly loaned the space his setup The kit is to be considered Hackspace infrastructure and is not to be hacked, but can be used with respect. As always, please clean up after yourselves, and return the equipment to where you found it. (Mention the permanent location of the kit here)
