Hoffman has an updated V60 method for single cup brewing after feedback from viewers. The difference compared to his previous method (where he is making more like 500 - 600ml of coffee) is that he splits the pour into 5 (1x50g bloom + 4x50g equal pours for 250ml of coffee) the effect being to slow it down compared to this bigger volume method where he does bloom + two larger pours.
So this makes it more or less identical to the method
@AndrewR mentioned above with the main point being to slow everything down a bit. This is interesting, although I have been using Hoffman's method with both 1-cup and 2-cup volumes just fine, albeit with a much slower pour than it seems everyone else was using. I get my 300ml of water in by about 2 mins and a total drawdown of about 3:00 to 3:10.
I suspect Andrew's guy achieves much the same result not least as Hoffman lays out this very precise timing and volume of the pours and then stresses that it doesn't really matter. So I think what matters most is the total time it takes to get all the water in which the guy in Andrew's video expresses as "don't fill too high, pour slow, let it drain" and Hoffman expresses as "50g over 10s, pause 10s, repeat (but don't worry about this too much)". I think this is a bit confusing from Hoffman and a bit too anal retentive and the other bloke expresses it in a much more useful way.
(Also Hoffman calls this multiple small pours "pulse pouring" which is not how I have seen the term used before where it has meant continuous pouring in small drips, which again I suspect is just a proxy for slowing it all down a bit).
Anyway I though that was interesting and I shall try it using Hoffman's method this afternoon. Although I suspect I don't have the patience for the precise timing he uses.
