Pourover Kettle Thread

While you guys were posting I made a major modification to my post explaining why a big base/narrow tip is needed for an ultra controlled pour. I'd be interested to see if it makes sense. :)

I understand the principal you're describing and think it makes sense, but only if the spout is offering some resistance to the volume coming into the base.  At the flow rates we're pouring at, the water is coming out slowly enough that IMHO having the wider base won't matter.

Before, if the flow was too slow, it would dribble, and to get the dribble to stop it had to flow faster than I'd like.  Now it'll flow slower w/o dribbling.
Yup. The dribbling with both of my pots is why I started reading this thread. I hate dribbling on my desk at school--I use the electric Bonavita there. I was going to change up and use a hot plate and the Hario, but that dribbles just as much. Looks like some blacksmithing is needed. :)

Having the tip of the Bonavita spout squished does help.  I can get a smaller stream to flow more smoothly.  Before, if the flow was too slow, it would dribble, and to get the dribble to stop it had to flow faster than I'd like.  Now it'll flow slower w/o dribbling.

It confuses me more than explains anything.

I might do another vid if I can think about this for a second..

The narrowing of the neck diameter creates the resistance. The neat thing about friction & resistance is that it doesn't take a big change to have a big result. The only difference in breath control for a vocalist is the narrowing of the throat. For an instrumentalist, the throat, mouth, and the embouchure (mouth opening) are narrower. Even for a big bore horn like a tuba, the elements are the same as for a flute.

The "S" of the Bonavita is too tight; it should be more stretched out and horizontal.


I agree, this is the first thing I noticed when comparing the roadshow Bonavita to my Paico kettle. See the link below with picture for comparison.

But I still think the above only applies if you're pouring fast enough for the smaller spout to offer some resistance, and don't think we do.

A friend ordered one of these for the rectory. Seems like a bit frou-frou for the pour over faithful, but it looks like it'll work well enough.

That is a nice looking unit.

You going to put it to good use Robert?

Will I ramble on more?

Yes...yes I will.

I don't think the wider base spout tapering down can matter much if at all.

Now that was an excellent over-analysis!

Are you going to venture out and take the pliers to your kettle like Peter?

Not a chance.

As stated I'm not sure a higher level of control is either possible or needed than what I have now.

Yeah, I can see by your pours a very fine level of control.
