The Hario V60 Trials and Stewardship of Time

Oriole Coffee Roasters' Ethiopian Harrar + Hario V60 + Hario Buono drip kettle
Assume only one brewing device: the single-cup Hario V60 - 01.
Assume a similar grind: dialing in at 3 notches from zero on the Hario Skerton.
Assume also a dose of 23g of the same beans (but no two beans are the same!).
Assume even a water temperature of 93 degrees celcius.

There are still too many factors to vary in search of the perfect cup:

Brew Ratio
The market norm is said to be 60g coffee for 1l water. But everyone has their sure-hit ratio. Plus this is probably dependent also on actual grind size of beans, type and roast profile of beans, maybe even composition of water, etc etc
- Stumptown Coffee: 23g with 11oz water for 8oz coffee
- Counter Culture: 1.6 - 2g per 1oz water
- Brown Coffee Co: 18g; 11 fl oz of water at 204F to yield 10 fl oz (via bitterpress)
- Taylor St Baristas: 23g with 320ml water
- Trevor Hyman (Bean Vagrant): 29g with 500g water

Boiling the water
To boil water in the Hario Buono drip kettle or not?
Filter water or tap?

Pre-wetting
To pre-wet or not? Theoretical grounds (haha) for pre-wetting include allowing the carbon dioxide trapped within the beans during roasting to be released, ensuring even extraction of the grounds

Circular pour vs center pour
Raised (though not high and dry) most famously in Scott Rao's "Everything But Espressp". See Matthew P Williams' post for a re-think.

You know that this is an all-important topic when Hitler gets emo about it.

To allow all the water to drip through or to stop near the end? If so, when to stop the flow?

Oriole Coffee Roasters' Ethiopian Harrar + Hario V60
Bean: Ethiopian Harrar, Oriole Coffee Roasters
Time from roast: 5 days
Grind: 2+ notches from zero on the Hario Skerton
Brew Ratio: 23g to 11 fluid oz
Water Temperature: 93 degrees celcius
Pre-wetting: yes (but didn't record how much water was used or whether allowed bloom to subside)
Pour: circular
Drip-through: yes, all the way to the last drop
Taste: floral but sour on finish when cold

Oriole Coffee Roasters' Ethiopian Harrar + Hario V60 Oriole Coffee Roasters' Ethiopian Harrar
Bean: Ethiopian Harrar, Oriole Coffee Roasters
Time from roast: 6 days
Grind: 3+ notches from zero on the Hario Skerton
Brew Ratio: 23g to 8 fluid oz
Water Temperature: 93 degrees celcius
Pre-wetting: yes (but didn't record how much water was used or whether allowed bloom to subside)
Pour: circular
Drip-through: no
Taste: floral, lovely even when cold but somewhat bitter when added to milk!

mojotogo
But such record-keeping is hardly accurate. What about the percentage of extraction and total dissolved solids via extractmojo or mojotogo + refractometer? Will these numbers necessarily give a good cup?

Drink Your Words coffee journal
And since the smelevision and tastovision has yet to be invented, words are the only means of recording taste, perhaps via coffee journals like 33 Coffees or drinkyourwords.

Still, exciting stuff!

The attempt at keeping records of these little variables and examining how small things affect the end product, has made me curious about my stewardship of time. So i've had a go at listing the goings-on of the past week.

On one hand, it is useful to keep close accounts of resources gifted to one by God (still alive = gift of time) so as to be considered about the spending of such resources, and additionally in my case, to ensure i stop double-booking the same time slots.

However, there is the danger that is somewhat similar to the danger of census-taking (especially wrt the Old Testament), and also the danger of doing this all for the sake of ticking off the to-do list and being smug and self-congratulatory about all this activity (or v.v.).

So, just a once-off snapshot for future reference (to satisfy own idle curiosity in future about how 2011 went by in a flash):

evening: a refreshing pint and chat with the bartend at The Cider Pit (by East of Avalon Wines) - a yummy Westons Vintage Organic Still Cider on draught (but it's flat, bitter and like chou dou fu, said the disbelieving bartender), groceries at Parkway Parade

night: spent quality time with B. Taylor and J.S. Bach + Violin Concerto to give vent to pent-up music, wrote this post

Obviously more concerted effort needs to be made to make full use of time - need to carve out time for exercise before turning completely into a lard-ball and for keeping up with current affairs and to some extent, pop culture so my references aren't too obsolete to be of much use in explanations, but being aware of how time is spent is useful step in hopefully the right direction...
