Harvest of wild hop from garden, 2015


Brewing beer is easier when you think.

There's a number of people in the space and other 'interested parties' who'd be interested in putting together a number of things to aid in the brewing of beer. A number of them have already brewed before; sometimes only from 'syrup', however, and not from 'full grain'.

The aim of this project is to get together a group of people and pick a date and place to bring a number of tools together and perform the brewing of a few batches of full-grain beer. Expect to learn how beer-brewing takes place, as well as be experiencing all the associated skills that go with it. It's likely we'll need to weld a stand for a burner that'll support a 50-liter brewing-vessel. We'll need to work on adjusting/tuning/extending the malt-mill(s). We might even venture into automatic temperature monitoring and regulation, etc etc. etc.

In other words; all the best things of all disciplines mashed up together.

BeerBrewDay II - FirstOfMayBeerBrewDay - 2016-05-01

Yay! Beer Brew Day II is upon us!

We're going to go for a ServerRoom Saison; nicely kept at a high fermentation temperature by use of the electrons we recycle in our server-room ! (or is it the holes we're recycling....current is so confusing).

We'll be trying to bring a number of beers with us from the previous brew-day, as well as some personal brewing experiments from home. Likely, we might brew a second beer too; style yet to be determined. Suggestions welcome !

Some other highlights:

  • New pully-driven barley-mill arrangement. Exciting amount of possible failure-modes !
  • High-volume batch brewing with small-batch equipment. How to get the most out of your gear
  • Invitation to people to bring their brewing-kits: let us help you brew your first/better beer!
  • Guide into the entire process for novices
  • Opportunity for asking questions about the finer points of the process.

More information can be found on FirstOfMayBeerBrewDay event-page!
