I started with a $10 Home Brand lager kit. It's basically malt and some hops already ready to go. I have tried these before, and played around with using less sugar or using two cans of malt instead of sugar - but for this I decided to just follow the recipe. One can of malt, on kilo of sugar, 25 or so litres of water.
The kicker was about 150 grams of cascade hops, half were boiled in some water for a while to (maybe?) bitter up a bit, and the other half were just thrown in the fermenter to dry hop while it fermented.
I left it for two weeks, and then bottled in 1.25 litre PET bottles. Why? Because they hold the pressure fine, and because bottling 25 litres of beer took 15 minutes, not half a day. I sanitized the bottles with boiling water, and used mainly sparkling water bottles as we dont have a soda stream so we buy heaps of soda water... Dont judge us, we are recycling the bottles by conditioning beer in them.
I used Safale US-05 Ale yeast instead of the questionable yeast that came with the home brand kit, and let me tell you! After fermentation I felt like I was smelling a really nice citrusy IPA - the wort tastes fantastic, so hopefully it gets better while carbonating / conditioning.
Total cost (cheating, hops and yeast were free from Dave...) $11. Next time, when I buy my own hops and yeast that might climb to $20 or so, so about $0.80 a litre or $0.26 per standard 330ml beer bottle. And total time brewing + bottling + cleanup is about an hour. Havent tasted it yet, but thats PREEEEETY good. Sit tight, I'll update this post when I've tried it!
