Ignoring the fact that this is marketing dross and relates to our favourite mega-brewer, I found this -> http://www.rockwellautomation.com.au/ap ... s_a-brewin

to be quite interesting.

I then got to thinking about my kilowatt-hour per hectolitre rating.

For a (nominal) 20 litre (0.2 hl) batch:

Wort Boil:
2 hrs at 2400Watts = 4.8kw-hr

Ferment Cool:
One week (24x7) at 80Watts @ 20% duty cycle = 2.688kw-hr

Wash Water Heat (Assume same as Wort Boil):
4.8kw-hr

Transport (ingredient collection), web-surfing (recipe formulation and *cough* research) Assume same as Ferment Cool:
2.688kw-hr.

Total (for 0.2hl): 14.976kw-hr
Total (per hectolitre): 74.88kw-hr

Ouch.

So approx, what is the cost of your power for 1 brew?
I've always wondered how many $ of electricity I use per brew, so you may be able to give me an approximate figure from your experience (if you feel so inclined).

12-15c per kilowatt-hour is a reasonable figure to work from. at those figures you're looking at $1.80 - $2.25 per 0.2 hectolitre (20 litres).

Hmm..... I wonder if these changes will result in a cheaper product?

What's the deal with this hectolitre thing? can't we restrict ourselves to measures of volume that most chemical engineering students are aware of?

1 hectolitre=100 litres

That would be:

'pint'
'pot'
'bucket'.

I for one welcome our new unit-ignorant overlords.

LMAO

One hectolitre equals 1/25,000 Olympic swimming pools. I'm not sure how many Libraries of Congress or Volkswagens that is...

You have too much time on your hands.


Brew more beer.

Now don't get all emo on us...

I need a humour transplant.

Yeah, i guessed that, but who actually uses this unit on a day to day basis?

Spills, I'm very familiar with those units of volume.

From what reading I can fit in these days, it seems to be a fairly common unit of measurement for small-medium sized breweries, particularly in Europe. I think it is bogus, myself, as you could just as easily use litres, but it is probably similar-ish to some old measurement that has been deprecated in favour of metric and allows all the old-timers to do a quick and dirty conversion.

Kind of like the way you do with ... well ... nothing at all now that I think about it...
