The Chestnut Slim grinder from Timemore is a really high spec, but accessibly priced, hand grinder which we’ve been thoroughly impressed with in our testing. The following relays our experiences with the Timemore Chestnut Slim, but if you’d rather experience it in video form, head straight to the bottom of this piece or click here.

An Overview
Equipped with 38mm hardened stainless steel conical burrs, these are designed primarily for filter brewing, but there is also an option to upgrade the burr set to Timemore’s ‘Spiked to Cut’ stainless steel burrs, or their 6 point titanium coated burrs if you want to prepare your coffee as espresso. The solid metal chamber of the Chestnut Slim means that the drive shaft is held securely in place and offers that bit more durability and an improved grind profile versus the Timemore Chestnut C2’s moulded plastic chamber.

Weighing just 430 grams, the Slim can be conveniently disassembled and broken down into component parts for travel – and that’s all made even easier using the included travel case. At just 45mm in diameter, it also fits perfectly inside an Aeropress, and the wooden handle is removable, saving even more space. It then magnetically clicking back into place when you’re ready to grind. 

The outer casing of the grinder has a diamond patterned knurled finish, providing a textured grip, which makes the grinding experience that little bit smoother and ergonomic. The design of the handle and bearings inside the driveshaft all contribute to a very smooth grinding action, and we’re really impressed with the speed of the grinder – when grinding for a single cup V60, we’ve consistently been able to grind 15g of coffee in around 20 to 25 seconds without breaking a sweat. 

Grind Adjustment & Recommended Settings
The grinder can be adjusted by fully closing the adjustment dial to the ‘zero position’, winding it all the way around clockwise until the crank handle ceases to move and then counting the clicks back to your desired grind setting

When it comes to dialling in for specific brew methods, there are some really useful jumping off points mentioned in the instruction manual that comes with the hand grinder. These are useful in guiding you before you settle on your own preferred grind settings for whatever brewer you’re using to make your coffee,  but we have also trialled the grinder to establish our own suggestions:  

Aeropress (1 minute steep): 16 clicks
Aeropress (2 minute steep): 19 clicks
V60 (single cup 15g): 18 clicks
V60 (two cup 30g): 22 clicks
Clever Dripper: 20 clicks
Steepshot: 15 clicks
French Press (500g): 24 clicks
French Press (1 litre): 27 clicks
Chemex (1 litre): 32 clicks

The maximum capacity of the Chestnut Slim is around 28g of whole bean coffee at a time if you’re using lightly roasted, dense beans. Any more than that and you’re really starting to push what the chamber and the grounds bin are capable of holding.  

Additional Features
With narrow hand grinders, it can be tricky to get your beans into the grinding chamber tidily. Timemore have made this a little easier by mounting the stabilising arms deep within the chamber, making this process considerably easier. We’ve found that weighing into the grounds bin of the grinder also makes it easier to load your beans more efficiently.

Another particularly thoughtful element of the Chestnut Slim’s design is the fact that the burrs are recessed into the body. This means you’re able to balance the grinder on your counter whilst weighing out your beans – a really nice feature that isn’t present in every hand grinder. 

Cleaning & Maintenance
After grinding, you can use the included cleaning brush to sweep out any chaff or bits of ground coffee that might cling to the burrs because of static build up. The amount of ground coffee retained is fairly negligible and we haven’t found the need to updose to account for grinds retention in this particular grinder. 

Following a fair bit of usage, you’ll want to deep clean the grinder, which is also fairly easy to do. Screw the grind adjustment dial to the coarsest setting and as you keep spinning it will come off completely, allowing you to access the burrs inside. Keep track of the order of each component you pull out so that can assemble it again properly in the correct order. The instruction manual will help you out here if you get a bit lost, so we’d recommend holding onto it. 

Nicely finished, the Chestnut Slim enlists durable, quality materials that make for a high spec hand grinder. Nice to hold, smooth to grind with and super adjustable, it’s priced appropriately and accessibly compared to other hand grinder options of a similar spec, and very capable of making delicious coffee on the go or with very little effort at home, regardless of your chosen filter brewing method.
