So I was bored on a conference call and the other grainfather thread got me thinking about relative costs. So to see where a GF pays for itself vs buying beer in the pub or shop I put together a chart.
Now I'm **** with Excel and couldn't fathom how to label the axis but the vertical axis is total spend in ã.
The horizontal axis shows total no. of pints.
I've assumed:
ã3.50 a pint in the pub
ã1.50 a bottle in the shop. (I'm ignoring the size difference between a 500ml bottle and a pint.)
ã600 for GFã15 per brew on ingredients (haven't factored in utilities, give me a break)
What it shows is the GF pays for itself after roughly:
180 pints vs pub (so 5 full length brews)
520 pints vs shop (so 13 full length brews)
