  1. For that particular coffee yes. However, my usual method involves a Dutch 02 filter held in a Biarro Alto filter holder so it's not really very comparable with using a Hario plastic 01 cone and Japanese paper. I have to admit to being surprised myself so far. I'm wondering if it something to do with 60% of the volume matching the top of the filter paper.
  2. Just tried it with another coffee in the plastic 01 brewer. This time a very light roast. It came through in 1:55 this time compared to 3:10 by my usual method - but it's another very good brew. I don't see the problem with it. No need to change grind size for me and it's just my normal single cup brew size 13.5/225. I'm surprised given that normally I go for minimal agitation. I've only got a few of the Japanese 01 filters left but I should be able to compare a few more coffees.
  3. Gave this a go after digging out my plastic 01 cone and Japanese paper for a 13.5/225g brew of a Brazilian washed catuai that I have been roasting recently. I was a bit sceptical due to the amount of swirling on show but it turned out to be a very nice brew. This is a typical Brazilian with a sweet nutty body and low acidity. Comparing it to my usual method (Dutch filter, Biarro Alto filter holder) same grind setting, minimal agitation there's very little tastewise to distinguish between the brews. A tad more mouthfeel (more visible oils on the surface) and a little more red berry flavour, possibility more rounded but less clean brew. I would guess a slightly higher extraction but will measure it next time. Hoffman method drains at 2:20 compared to 3:15 with the Dutch filter.
  4. Bolivia Flor de Mayo, Taipiplaya brewed as drip via Brewista steeping brewer. I got these greens from Pennine tea and coffee ages ago and have been trying lots of different roasting profiles. The flavours are unusual. It's sweet with a bakers choc and slightly savoury note (Bovril ish) together with hops and citrus (sometimes orange others lime). It's one of those where the whole tastes better than the constituent parts. I thought that the savoury note might be a roast defect but it always appears on all the profiles. Its not over riding so doesn't spoil the overall but rather brings back childhood memories of standing on the terraces watching football on a Saturday afternoon. I always hated the smell of half time pies and Bovril! One of the great things about coffee is remembering (or trying to) place a taste association.
  5. 14th roast of Costa Rica washed geisha La Candellila that I got in October last year. Should get 20 roasts on the Ikawa from 1kg. Brewed via drip using the Brewista Steeping brewer (1 central hole) Kalita 185 filter 13.5g/225. Brew time 3.35 with 40 sec bloom with the valve closed. I find that both the Brewista and Bonavita steeping brewers are very good for drip provided the pours are done with minimal agitation. Otherwise you may clog the filter. Light tea like body with exquisite lemon and tangerine sugary acidity. A very light roast - pretty crunchy on grinding. A little more heat pre 1st crack compared to some of my other roasts of this bean so that in terms of moisture loss it is higher than those but overall a lighter roast.
  6. I think that's a reason some brews end up looking pitted as it doesn't vary the holes it uses enough. It seems odd that it doesn't use all the holes. No two brews seem to turn out the same. Another possibility might be the Brewista steeping brewer which is a basket shape and takes 185 or larger filters and has a lever shut off valve and a single central hole? This was going very cheap a while back. Not sure if they still make them. Brewista also had their own branded 185 filters which drained slower than the Kalita ones but again they seem unavailable now. I got the brewer and filters from Coffee Hit a couple of years ago.
  7. I wonder if that was an enhancement to control pulse length. I'll follow your progress with the machine with interest but I'm not tempted to unbox it just yet. I can't ever see it being good at 225/250g brew sizes.
  8. I never tried normal brew mode into another vessel. Not sure it's recommended as such? Not that it matters if it works of course. My recollection of manual mode was that it pulsed about 70ml each time
  9. I found the 185 filters to be too small for brews near the max. Coffee particles would end up in the brew. Bunn would be better for max brews Good to hear you are still using yours and getting results.
  10. Thanks. Don't think it would be possible once a filter is on top. Are you using manual mode for the 185 brews on top of the carafe or auto?
  11. Must be the small chemex? My one is 21.5cm tall and you'd need to add on a bit for the filter. My Brazen is boxed away in a cupboard so can't easily check if it fits but I'm sure I did try it at some point and it was too tall. Unless the machine has changed since on account of feedback? No mention of a chemex in my edition of the manual.
  12. Don't believe everything a dude in a coffee shop tells you! You need either calcium and \ or magnesium to extract and a combination probably works best. Lots of magnesium doesn't necessarily taste good (try adding Epson salts). The BWT filter works by ion exchange, exchanging calcium for magnesium as I understand it. You have precious little calcium to begin with to exchange. The jug is designed to reduce water hardness which you don't want to do. Another alternative that I've not tried is to use a zero water jug filter to essentially strip everything away to 0 TDS then add a third wave sachet mix to it for supposed ideal water. You can buy these online. In the end it's just easier to buy some bottled water.
  13. How did you get the coffee in the thermos? Does the 185 balance on top with the lid off? It's just very slightly short for a small (3-6) cup chemex unfortunately. I think I sat my brewer on a tall French press jug with scales under.
  14. There is no advantage coffee wise using a BWT jug filter imo. You have very little mineral content to begin with, doesn't make sense to reduce that. I do use one for drinking and making tea as it tastes better and removes unwanted stuff like chlorine but for me it makes coffee worse. I use plastic bottled water because it produces coffee I like to drink. If I was using a significant amount I'd look at a plumbed in solution. But typically I'm using less than 400ml per day bottled.
  15. Reminds me of my experimentation with the machine! As you have discovered the filter basket really limits extraction compared to the wave filters. There are some other basket filters you could try like Bunn. I did experiments with it as a manual pour over and it worked well, but day to day it's just too much of a faff for me. If you can find the sweet spot for this machine and I reckon that to be in the 750-900g area it's probably a great machine, otherwise it seems inconsistent. I wonder how many of the original buyers on the thread still use it day to day?
