LHS barrel2.svg

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. :)

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.

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

Get in touch

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

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)


Full list of brewing equipment at the Hackspace:

Item Quantity Owner Notes
100L Kettle 1x Hackspace pledged incl. hop filter & ball valve
Gas burner 1x B3cft

80L Stainless mash tun 1x B3cft
Converted keg kettle 1x B3cft
29L Brupak Electric Boiler 1x Det Good for HLT. Element needs regular cleaning to prevent gunking up the thermostat

Gas bottle refills can be obtained from: http://www.londongases.co.uk/lgcalor.php They'll deliver and take away the empty for £32.50.

We currently have 2x 13kg propane tanks, both with standard 27mm screw-in regulator. Please make sure there is always one full. If one runs out and you start the new one, send an email to the LHS Brewing group to let us know, and perhaps start a pledge for a refill.


Gas status:

  • 13kg - Full
  • 13kg - 4.5kg (35%) remaining

The tare (empty) weight of a 13kg propane cylinder is 11kg.
