You bought a French press because someone told you it makes better coffee than a pod machine. They were right — but then you used pre-ground supermarket coffee and got a muddy, bitter cup with sediment thick enough to read your fortune in. The missing piece isn’t technique. It’s the grinder. A decent burr grinder set to coarse changes everything about French press coffee, and you don’t need to spend more than about £50 to get one that does the job properly.

Why Grind Size Matters for French Press
French press is an immersion brew method — the coffee sits in hot water for 4 minutes, then you push the plunger down to separate the grounds. This long contact time means the grind size controls almost everything about the flavour.
Too Fine = Bitter and Silty
If your grind is too fine (espresso or filter size), the water extracts too much from the coffee during those 4 minutes. You get a harsh, bitter cup with a thick layer of sludge at the bottom. The mesh filter on a French press isn’t fine enough to catch espresso-grade particles, so they end up in your cup.
Too Coarse = Weak and Watery
Go too far the other way and the water can’t extract enough flavour in the steep time. You get thin, sour, underdeveloped coffee that tastes like it was brewed with half the grounds you actually used.
The Sweet Spot
A consistent coarse grind — roughly the texture of sea salt or breadcrumbs — gives the water enough surface area to extract flavour evenly without over-extracting. For more on how grind size affects every brew method, our grind sizes guide covers the full spectrum from Turkish to cold brew.
Burr vs Blade Grinders for French Press
This is the single most important choice. Blade grinders chop beans randomly; burr grinders crush them between two surfaces at a set distance. For French press, the difference is night and day.
Why Blade Grinders Fail
A blade grinder spins a blade that chops beans into random-sized pieces. Some end up powder-fine, others stay in large chunks. When you brew with this mix, the fine particles over-extract (bitter) while the large chunks under-extract (sour). The result is a messy, inconsistent cup.
Why Burr Grinders Work
Burr grinders pass beans between two abrasive surfaces (burrs) set a specific distance apart. Every particle comes out roughly the same size. This consistency means even extraction — the water treats every particle the same way, and you get a clean, balanced cup.
Can You Get Away With a Blade Grinder?
Realistically? For French press specifically, a blade grinder is better than pre-ground coffee — but only just. If you already own one, use it as a stopgap while you save for a burr grinder. Pulse in short bursts, shake the grinder between pulses, and accept that the cup will be okay rather than great.
Our Top Pick: Timemore C2 Max
If you want one recommendation: the Timemore C2 Max manual grinder, about £50-60 from Amazon UK or specialist coffee retailers. It’s the grinder I’ve used daily for the past eight months and the one I recommend to everyone who asks.
Why It Wins
- Coarse grind quality is excellent — the stainless steel burrs produce a remarkably even coarse grind with minimal fines
- 36-click adjustment — enough granularity to dial in exactly the coarseness you want for your preferred steep time
- Capacity: 30g of beans, enough for 2 large mugs
- Build quality: Aluminium body, feels solid, nothing rattles
- Grinding speed: 30g in about 40 seconds — quick for a hand grinder
- Compact and portable — throw it in a bag for camping or travel
What It Doesn’t Do
It’s a manual grinder, so you’re cranking by hand. For one or two cups, this is fine — even pleasant in a morning-routine sort of way. For a family of four who all want French press simultaneously, an electric grinder saves time and arm effort.
Best Manual Grinders for French Press
Timemore C2 Max — About £50-60
Our top pick. Excellent coarse grind consistency, solid build, and the right price point for anyone who brews 1-2 cups daily.
Hario Skerton Pro — About £30-40
- Why consider it: Cheaper than the Timemore, widely available from Amazon UK and Lakeland. The ceramic burrs produce a decent coarse grind
- The catch: Ceramic burrs are slower and less consistent than stainless steel at coarse settings. The grind wobbles slightly at the coarsest adjustments
- Verdict: Good for beginners on a budget. If you’re not sure you’ll stick with manual grinding, this is a low-risk entry point
1Zpresso Q2 — About £70-80
- Why consider it: The best coarse grind of any hand grinder in this price range. Seven-core steel burrs, 38g capacity, gorgeous build quality
- The catch: At £70-80 it’s pushing into entry-level electric grinder territory
- Verdict: For the French press obsessive who wants the absolute best manual grind. If you brew pour-over and AeroPress too, the Q2 handles all three brilliantly
Porlex Mini II — About £35-45
- Why consider it: Ultra-compact, fits inside an AeroPress for travel. Japanese ceramic burrs, stainless steel body
- The catch: Only 20g capacity — barely enough for one large mug. The coarse adjustment is limited compared to the Timemore
- Verdict: A travel grinder first and foremost. Not ideal as your only grinder unless you exclusively brew single cups
Best Electric Grinders for French Press
Baratza Encore — About £130-150
- Why it’s the standard: The entry-level electric burr grinder that every coffee forum recommends. 40 grind settings, conical steel burrs, consistent coarse output
- UK availability: Amazon UK, Bella Barista, Coffee Hit
- Verdict: If you can stretch to £130, this is the grinder you buy once and keep for years. It handles French press, pour-over, AeroPress, and everything coarser than espresso. The motor is loud but the grind quality justifies it
Wilfa Svart — About £100-120
- Why consider it: Scandinavian design, flat burr set, slightly cheaper than the Baratza. The coarse settings are excellent for French press — I’ve compared it side by side with the Encore and the difference is marginal
- UK availability: Amazon UK, John Lewis
- Verdict: The better-looking option. If the Encore is a Honda Civic, the Wilfa is a Volvo — same reliability, nicer interior
De’Longhi KG79 — About £30-40
- Why consider it: The cheapest electric burr grinder that’s actually a burr grinder. It works for French press at the coarsest settings
- The catch: Retention is high (grounds stick inside the chamber), the grind isn’t as consistent as the Encore or Wilfa, and the build quality feels plasticky
- Verdict: A budget option that gets you into burr grinding for under £40. Expect to upgrade within a year if you catch the coffee bug
What Coarse Grind Actually Looks Like
This trips people up because “coarse” means different things depending on who you ask. Here’s what to aim for:
- Visual: Roughly the size of sea salt flakes or coarse breadcrumbs. You should see distinct individual particles, not powder
- Touch test: Rub a pinch between your fingers. It should feel gritty and granular, not smooth or powdery. If it clumps together like sand, it’s too fine
- The paper test: Tip some grounds onto white paper. If there’s a dust of fine particles surrounding the larger pieces, your grinder is producing too many fines — tighten or clean the burrs
- Brew feedback: If the coffee is bitter and silty, grind coarser. If it’s weak and sour, grind finer. Let your cup guide the final adjustment
How to Dial In Your Grinder for French Press
- Start at the coarsest setting your grinder offers
- Grind enough beans for one cup (about 15g for a standard French press mug)
- Brew with water at 92-96°C (just off the boil — wait 30 seconds after the kettle clicks) for 4 minutes
- Taste the result — is it bitter and silty, or weak and watery?
- If bitter: move one click coarser
- If weak: move one click finer
- Brew again and taste
- Repeat until you hit the flavour you like — this usually takes 3-4 attempts
Once you’ve found your setting, note it down (or mark it with tape on the grinder dial). You’ll only need to adjust again when you change coffee beans — different roast levels and origins extract differently.
The British Coffee Association notes that water temperature and grind size are the two biggest factors in brew quality — getting both right transforms your cup.
Manual vs Electric: Which Suits You
Go Manual If…
- You brew 1-2 cups per day — hand grinding 15-30g takes under a minute
- You enjoy the ritual — there’s something meditative about cranking a hand grinder at 7am
- You want portability — camping, travel, office desk drawer
- Budget is tight — £50 gets you a premium hand grinder; the same money gets you a basic electric
- Noise matters — hand grinders are near-silent. Electric grinders wake the household
Go Electric If…
- You brew for 3+ people — grinding 60g+ by hand gets old fast
- Convenience wins — press a button, walk away, come back to ground coffee
- You brew multiple methods — electric grinders switch between espresso and French press settings more practically
- Morning energy is low — not everyone wants an arm workout before their first coffee
The Honest Answer
For French press specifically, manual grinders punch above their price bracket. A £50 Timemore produces a coarser, more consistent grind than a £40 De’Longhi electric. If you’re only brewing French press and only making 1-2 cups, manual wins on quality per pound spent.
Features That Matter and Features That Don’t
Worth Paying For
- Stainless steel burrs over ceramic — faster, sharper, more consistent at coarse settings
- Stepless or fine-click adjustment — lets you micro-adjust rather than jumping between preset notches
- Large capacity (30g+) if you brew for more than one person
- Easy disassembly for cleaning — grounds build up in burrs and affect flavour over time
Not Worth Paying For
- Built-in timers on electric grinders — just weigh your beans before grinding
- Dozens of grind presets — you’ll find your French press setting and leave it there
- Glass hoppers — look nice, attract dust, break if dropped
- “Anti-static” features — these barely work. A drop of water on the beans (the Ross Droplet Technique) does more

Buying Tips
- Check the burr material before buying — some “burr grinders” at the £20-30 price point use ceramic blades that are barely better than a blade grinder
- Read the 1-star reviews — they tell you more than the 5-star ones. Common complaints about cheap grinders: inconsistent grind, static, motor burnout after 6 months
- Buy beans from a UK roaster — freshly roasted beans (within 2-4 weeks of roasting) make a bigger difference than upgrading your grinder. Our brew method comparison covers how to get the best from whichever method you prefer
Common Mistakes with French Press Grinding
- Using pre-ground espresso coffee — it’s far too fine for French press. You’ll get a bitter, silty cup every time. Buy whole beans and grind coarse
- Not cleaning the grinder — old grounds trapped in the burrs go stale and taint every subsequent grind. Brush out the burrs weekly, deep clean monthly
- Grinding too far in advance — ground coffee starts losing flavour within 15 minutes of grinding. Grind immediately before brewing, not the night before
- Ignoring grind consistency — a grinder that produces lots of fine dust alongside coarse particles gives you the worst of both worlds. Invest in a burr grinder that produces uniform particle sizes
- Storing beans wrong — even the best grinder can’t save stale beans. Keep them in an airtight container at room temperature, away from light and heat. Never refrigerate or freeze unless you’re storing long-term
- Over-filling the grinder hopper — cramming too many beans into a hand grinder forces them through the burrs unevenly. Follow the manufacturer’s capacity recommendation
Frequently Asked Questions
Can I use a blade grinder for French press? You can, but the results will be inconsistent. Blade grinders produce a mix of fine dust and large chunks. For French press, this means some particles over-extract (bitter) while others under-extract (sour). A burr grinder solves this for as little as £30-50.
How coarse should I grind for a French press? Aim for the texture of coarse sea salt or breadcrumbs. If you can see individual distinct particles and they feel gritty between your fingers, you’re in the right range. If the grounds look like sand or powder, go coarser.
Is a hand grinder better than an electric for French press? At the same price point, yes. A £50 hand grinder (like the Timemore C2 Max) produces a better coarse grind than a £50 electric. The trade-off is effort — you’re cranking by hand for 30-40 seconds per cup. Electric wins on convenience if you’re grinding for multiple people.
How much should I spend on a grinder for French press? £30-60 gets you a good hand grinder that will last years. £100-150 gets you a solid electric grinder. Spending less than £30 usually means blade grinders or very low-quality burrs — worth avoiding. Spending more than £150 only makes sense if you’re also brewing espresso.
Do expensive grinders make better French press coffee? Up to about £100-150, yes — you’re paying for better burr quality and grind consistency. Beyond that, the improvements are marginal for French press. A £400 grinder designed for espresso produces a fantastic coarse grind, but so does a £60 Timemore. The diminishing returns kick in much sooner for coarse brewing than for fine.
