Coffee Chronicler's Switch method is my daily driver anymore. It gives me a good quality without needing my brain cells to talk to each other too much in the morning.

Here's what I got as an interpretation of Lance's Next Level Pulsar recipe. Apologies in advance for any mistakes.
Lance Hedrick Recipe: 1 :16
Dose: ~XXg Water: ~XXXml
Rinse paper
Close valve, Pour Coffee & level bed w/ WDT
Pour water ~3x coffee weight, WWDT
Steep ~1 minute then drain
Close valve then pour ~XXXml water (~8-9x dose)
At 4 minute mark open valve & leave open
Final pour w/ valve open to desired weight
~6 minute TBT
Just got my Pulsar & i'm going to go try this now 😃

The more I hear these experts talk, the more I realize Mr. Coffee has it right: A constant flow of fresh solvent (water) and no sitting extracting "the bad stuff" at the end.

Following Lance Hedrick is like subscribing to Masterclass! Wow! He provides so much subtlety in his breakdown of topics. I have one "lightbulb moment" (knowledge hitting the mark) after another. For something that's so technical and detailed, it's actually quite thrilling to experience. I now understand why all these devices keep arriving, how they're optimized, and which one I might prefer given my taste and equipment. Rewatch the section starting at 4:30 where he introduces the problem of "extracting coffee with coffee" and teaches the need to "introduce clean solvent." Mind blown. So fun and informative. Thanks Lance.

For the least bypass Hario Switch, you can replace the default glass Hario V02 with Hario's own Mugen dripper. The Mugen is made with plastic so it has good heat retention and does not have the reservoir issue when using with Kono dripper.

Lance, thanks for igniting this passion for coffee in me. You have played a large part with your informative and easy to understand content. I’m considering leaving my corporate 9-5 to help a friend open a coffee shop.

[tempusrob]

Your pulsar recipe is far and away the best one I've tried so far. Was ready to give up on it. Thank you!

[philipdeppen]

I just tried this with my hario switch with an awesome Guatemalan medium light roast. Came out with a great balance of sweetness body and sharpness. Brought out a great grapefruit taste. Love my hario switch lol Ty so much

[tesilab]

I am shocked-- SHOCKED --to see Lance making coffee with so much CHAFF (see 17:52 doming the pulsar)

[jaricklosey]

That Pulsar looks awesome. It's like the Switch crossed with Aeropress crossed with Drip Assist. If it's durable enough for travel and the filters aren't crazy expensive, might be endgame for pour over!

[sardonically-inclined]

I've had my Switch for a while, but for the last week I've been making my coffee using your method and its quality is both good and consistent. Just wanted to say thank you.

[german.galvis]

That WDT looks rad - anyone knows what's the brand/model?

3:53 Small correction: Immersion is not more efficient than percolation, it is less efficient, which is a logical consequence of the Noyes-Whitney equation which says, that the speed (=efficiency) of dissolving something is proportional to (cs - c)
cs is the maximum possible concentration of the particle in the solvent and c is the concentration at a given moment.
As immersion brewing has the solvent getting more saturated, c gets bigger, so (cs-c) gets smaller and so does the speed of dissolving. Percolation however does regularly add new solvent, thereby reduced c, which increases (cs-c) and the speed of dissolving.

However, it is explained correctly from that point onwards.

[michaelmetri]

As someone who was mainly using the Devil recipe with the switch and getting great results, I'm very excited to try this!

[WeAreBullets]

also, thank you dear Lance for the info, all i want in life is an easy way to get a good cup without having to think too much or do too much math and use too much stuff. that's why i always did french press without the press, i just carefully poured it out thru a metal strainer, low waste and easy. i only wish there can be a way to get a clean cup without having to use paper filters all the time. i know theres cloth options but that feels a bit gross lol. if you have any good sustainable self-sufficient filtering ideas please let us know. maybe i will have to try fabric tho

[MrKent]

Just tried this Pulsar recipe performed in the video. I’ve been doing it wrong the whole time. 😅
This made my already amazing coffee even more amazing. It brought out the complexity of it and the aromatics were 🤌🏼
My new daily recipe for sure

Good to see equilibrium extraction of immersion brews getting some attention, and noting that finer grinding is so important for this reason. One point I’d note is that research has shown that this is temperature independent. So yes, it applies from boiling…all the way down to the coldest of cold brews: equilibrium all the way, baby! Letting it brew long enough to *reach* equilibrium is the key, so if you’re still struggling even after switching to a finer grind…then just let it brew longer! You will not over-extract, because equilibrium. 👍

[davidlundholm]

Brilliant! Particularily the introduction and details about immersion vs percolation.

However, what prevents a percolation from becoming immersion considering the water hangs out with the grinds anyhow while percolating…

Is it infact the gravity and constant flow that dictates a percolation?

Is it so that in pour over perculation the water above the bed stays water (ie not dissolved coffee)?

[ResponseDigitalMedia]

Thanks, very detailed and scientific! I just leave the pot off my $19 drip Black & Decker for a couple minutes and it basically gives the same affect - Walmart style!

Love Fellini in the background 😆 to anyone who hasn't seen his movies, I highly suggest you do, they are great 😀
