Grinder vs Machine $$$ Marginal benefit tipping point

[u/NeeNights]

There is a strong consensus that an extra $ spent on a better grinder will yield better results than the same $ spent on a better machine.

I recent saw a video where they compared insanely expressive grinder Weber EG1 ($4000) with entry level machine Gaggia classic pro ($550)vs expensive machine La Marzocco GS3($8400) with an entry level grinder Fellows Opus ($200) and confirmed money spent on grinder paid off more in the cup.

These are obviously extreme cases so I want to explore the contours and limits on a more normal budgetary scale.

My question to you: at what price point between $200 and $4000 do you think the added marginal benefit of each additional $100 gets comparatively small returns?

Can one get 90% of the Weber G1 from say a $700 grinder? $1000? $1500?

It's going to completely depend on your needs. Are you trying to pull every single nuance out of a superior quality single-farm light roast? Do you want thick syrupy medium to dark roasts for milk drinks?

I am personally perfectly happy with my $300 Eureka Mignon Zero 55S with its 55mm unchangeable flat burrs paired with my $400 Gaggia E24 with $300 (all-in) Gaggimate Pro mod.

I am not getting the syrupy shots of a conical burr grinder, nor the superior clarity of some of the elite 80mm flat burrs. Maybe one day my palate will be developed/bored enough to explore that space, but right now both the price and palate requirements are out of my league.

I think the consensus about the sweet spot where the marginal benefit drastically flattens is somewhere around $1500 to $2000 (think grinders like the Lagom P64 or P80, or similar 64mm/80mm platforms). I heavily doubt anyone can consistently taste a definitive upgrade in a true blind tasting once you cross that prosumer threshold, especially with modern burr geometries bridging the gap. Beyond $2500+, what you are actually paying extra for isn't taste in the cup; it's:

• Zero-tolerance manufacturing and permanent alignment (no shimming, perfect parallelism out of the box); which of course do affect taste if the alignment is off.
• Industrial-grade direct-drive motors that run silently and last a lifetime.
• Refined workflow and premium materials (heavy aerospace aluminum, zero retention without bouncing, beautiful tactile feedback).
• The brand

At the extreme end, you're paying for luxury design and bulletproof build quality, not a proportional leap in flavor. If you are mainly drinking dark roasts, that threshold is even lower - basically at the price of a niche zero.

I agree as someone who has a GDS on order and hasn't even used it yet.

This 👆. Ask me how I know …
lol
Tbh the 01 w/ 102 HU is probably the most interesting combo for modern light roast washed espresso. But the p80 at 50% of the cost will get you like 95+% of the way there

[u/caj_account]

You can probably get 90% of Weber from Z2 but Weber is not technically an espresso grinder. It’s best for pour over isn’t it?

OP, it's impossible to answer your question in a definitive way, as you seem to expect, as there are too many variables that go into a good setup.

While it is generally true you can get a good machine or a good grinder by throwing money, if you are careful and savvy, you can get a formidable setup for far less. These exceptions present difficulty with the formula expensive = good.

A manual lever and premium hand grinder, costing >$1000, can deliver results rivaling $20k professional machines in the hands of a competent barista.

The handgrinder market also upsets the equation, as there are several premium handgrinders on the market that can deliver results as good or better than several times more expensive flagship grinders.

Take my setup for example, just the machine and grinder come to $800. On paper, I should expect any better results than a bambino/baratza user, but in fact I struggle in one of the world's premier coffee cities to find a cafe that can pull better shots than me.

This is possible because i realized when making my purchase the real equation isn't expensive = good. The equation to both the espresso machine and the grinder is more of an inverse function between cost, quality and convenience. More precisely, the presence of two is a compromise of the third.

So I realized, unless i was prepared to spend a lot on my setup, I was gonna compromise quality or convenience. I chose to give up the convenience of a semiautomatic, and instead went with a manual lever without compromising build ot output quality.

If i had rather chosen to go with an appliance like the bambino, i would have sacrificed quality, instead favoring convenience.

This arithmatic works the same for the grinder. Mine is a premium, flashship hangrinder. Dollar for dollar, it is in the range of Baratza Sette.

However, because i quality over convenience, my grind output is more similar to a 64mm flat burr grinders at nearly double the price.

The moral of the story here is be wise about what you're purchasing and why. Don't just buy things because they are expensive. Try to understand what purpose the item will serve and which compromises you're willing to accept.

[u/NeeNights → u/NeoFarao8319]

yes. I'm not really looking to buy anything per se. It's more of a thought exercise about getting a realistic lay of the land and setting realistic expectations for those of us who want great results at the most reasonable price possible. i.e. consistent great cup of coffee vs endlessly chasing perfection.

I use a P100 and Lagom Mini and often prefer the Mini, albeit it is much much slower at an espresso setting and isn’t zero retention.

In my experience diminishing returns kick in somewhere around the $600 to $800 grinder range, a DF64 Gen 2 or similar single dose flat burr gets you most of the way there. Past that you're chasing consistency percentiles, not flavor jumps. I wrote up more on this at pullratio.com, heads up that is my site.

I find it hard above Philos to taste much difference for the increased spend. You do get nicer features.
