FrontStreet Coffee's Recommended Entry-Level Manual Coffee Grinders for Home Use

Coffee grinders can be either manual or electric. Among electric grinders, there are blade, conical, flat, and ghost tooth types. Detailed introductions and comparisons are covered in this article. Although electric grinders are convenient, their bulky nature makes them difficult to carry, giving manual grinders more significance. There are several specific models of manual grinders that are particularly recommended, which this article will introduce to you.

Pros and Cons of Manual Coffee Grinders

Advantages: No electricity required, generates less heat (reducing loss of aromatic compounds), easy to carry, and simple to disassemble and assemble.

Disadvantages: Requires physical effort and has limited grind fineness.

The disadvantages of manual grinders are the physical effort and time required. Making pour-over coffee gives people a leisurely feeling, and using a manual grinder that requires effort seems to contradict the original intention, which led to the creation of electric grinders. Additionally, electric grinders can grind beans into finer coffee powder, something many manual grinders cannot achieve. However, models like the HG ONE can grind coffee beans to espresso-grade fineness, though they require considerable effort and expense.

Conversely, the advantages of manual grinders include no electricity consumption, lower heat generation during grinding, and portability. If your workplace doesn't have space for an electric grinder, a manual grinder can be a lifesaver. Most importantly, proper "cleaning" after each use is essential, as residual grounds and rust can affect each batch of coffee beans. Thorough cleaning ensures the pure taste of every cup of coffee!

Anonymous Coffee Grinder

Opening forums like M01 or the PTT coffee board, you'll see many people recommending this Anonymous Coffee Grinder. The logo features a cat in a coffee pot. The current Anonymous grinder is now in its second generation, known as "Anonymous 2," designed by Anonymous Coffee Studio. It comes in two versions: single-origin and espresso, with prices differing several-fold. Anonymous 2 offers five color options: red, black, gold, silver, and blue. It features an aluminum alloy shell that is both lightweight and sturdy, with grinding burrs made of stainless steel precision-processed by CNC to ensure quality when grinding coffee beans. The bearings use Japan's NMB brand, offering high precision and smooth operation.

In many people's practical tests, the coffee grounds produced have very few fines. Although manufactured in China, it has gained high recognition in the community due to its quality materials and excellent design. Group purchases often see enthusiastic "+1" responses. Currently, the known purchasing channel is through Taobao.

Porlex Manual Grinder

Another frequently recommended Japanese brand manual grinder is Porlex, which features a well-designed removable handle, fewer fines compared to many brands, and a Mini version that's even more portable. The ceramic grinding burrs are a small advantage, while the drawback is that the metal body makes it easier to slip and heat up during use. Many solutions to this issue have been introduced online.

OE Lido 2

Practicality and Design:

Some people create innovations in their daily lives. Orphan Espresso manufactures the most expensive, dream-like manual grinders on the market, and their latest creation is the Lido 2. It looks like the notorious jar from "Teenage Mutant Ninja Turtles II: The Secret of the Ooze," except it can't turn dandelions into terrible monsters (or turn turtles into crime-fighting heroes). This Cadillac (or McLaren P1) of grinders performs best among those mentioned here. It's priceless, expensive, and even performs well in harsh environments. If the power goes out, you don't need to worry about being affected. Made from durable plastic, glass, and stainless steel, it weighs 3.5 pounds, making it completely unsuitable for travel. So why would you need it? The Italian-made steel blades can pulverize an ounce of coffee in just a few seconds. While a Hario requires 40-50 turns to grind beans, the Lido can do it in just over a dozen turns.

Is this the best? The grind adjustment is a bit tricky, and the strength required to operate the grinder might not compensate for this. The author had their father and girlfriend test it, and they found it difficult to hold and operate this bulky grinder. While it wasn't too difficult for the author, who actually enjoyed the consistent power of the Lido 2 during grinding. The Lido 2 can hold up to 8 ounces of coffee grounds, so if you're making coffee for a group, this manual grinder would be very suitable for you.
