the making of bitter. This in turn has led me to the realisation that I've literally no idea how one goes about making beer.
Anyone have any idea where one starts?
It was a popular pastime in the 1970s, brewing your own beer. I had a friend whose family business was making and selling kits to do it. They made a fortune for a while, expanded rapidly, and then the whole thing collapsed around their ears. I suspect you can still buy a kit, though. (It's going to taste like liquid sewage.)
Yup.
Walk into the Shamley Green shop, pick up 4 cans of Budweiser and 4 cans of whatever strikes me i.e. San Miguel, Fosters etc, pay for it, take it home, drink it.
Job done.
