== London Hackspace Brewing ==


A successful inaugural brewing session was held at the new Hackspace on the [[2013_August_Open_Day]].
London Hackspace had an active homebrewing subgroup at the old Hackney rd location. We still have a shared full-mash gas-fired brewing setup which is capable of a brew length of about 80 litres, as well as a CO2 keg dispense system. Anyone can participate, even if you've had no experience before, there's always cleaning to be done. :)


Brewing as a "project" is being driven by [[User:Detonate|Det]], helped by [[User:Ross|Ross]], overseen by [[User:Russ|Russ]] with equipment borrowed from [[User:B3cft|B3cft]].
Since our brewing equipment is gas-fired and the space isn't well suited to the steam produced, we brew outside on the loading dock. This is more pleasant in the summer than in the winter.

== 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.

If one runs out and you start the new one, send an email to the [https://groups.google.com/forum/#!forum/london-hackspace-brewing LHS Brewing group] to let us know, and perhaps start a pledge for a refill.
