Tru Conical Burr Coffee Grinder: What You Need to Know

The Tru conical burr coffee grinder was a budget-friendly option that showed up in stores like Walmart and Target for around $30-50. If you've come across one at a thrift store or have one sitting in your cabinet, you're probably wondering whether it's any good. The honest take: it's a decent starter grinder that beats a blade grinder every time, but it has real limitations once you start caring about grind consistency.

I've used a few of these budget conical burr grinders over the years, and they all share similar strengths and weaknesses. Let me break down exactly what the Tru grinder does well, where it falls short, and whether you should keep using yours or move on to something better.

The Tru Brand and What They Made

Tru was a small appliance brand that produced a range of kitchen gadgets including coffee grinders, toasters, and blenders. They weren't a specialty coffee company by any stretch. Their grinders were sold as affordable alternatives to the $100+ models from Baratza and Breville, and for a while they were one of the cheapest conical burr grinders you could buy.

The most common Tru grinder model featured a plastic body, a simple dial for grind settings, and a small hopper that held about 4-5 ounces of beans. The conical burr set was made from steel, though the quality of the steel and the precision of the machining were noticeably lower than what you'd find in mid-range grinders.

Tru has since become harder to find in retail stores, and the brand appears to be discontinued or at least scaled way back. Replacement parts are nearly impossible to source, which is worth knowing if yours breaks down.

Grind Quality and Consistency

Here's where things get interesting. The Tru grinder produces a grind that is noticeably more uniform than a blade grinder. If you're coming from a $15 blade grinder that chops beans into random-sized chunks, you'll see an immediate improvement in your cup quality.

That said, the grind consistency has real limits. At coarser settings (French press range), the Tru produces a mix of medium and coarse particles with a fair amount of fines. You'll see dust alongside larger chunks, which leads to muddy French press coffee and over-extraction.

Medium Grind Settings

The sweet spot for the Tru grinder is the medium range. Drip coffee and pour-over at medium settings produce reasonable results. The particle distribution is tighter here than at the extremes, and most people brewing with a standard drip machine won't notice the inconsistencies.

Fine Grind Settings

Espresso is essentially off the table. The Tru can't grind fine enough or consistently enough for pressurized espresso, let alone unpressurized. Even for Moka pot or AeroPress at fine settings, you'll get a wide spread of particle sizes that makes extraction unpredictable.

How the Tru Compares to Modern Budget Grinders

The budget grinder market has changed a lot since the Tru was at its peak. Back then, $40 bought you the Tru or maybe a Cuisinart DBM-8. Now that same budget gets you options like the Bodum Bistro or even entry-level models from brands like OXO that offer much better consistency.

If you're looking at the Best Burr Coffee Grinder options right now, the floor has risen dramatically. A $50-70 grinder today will outperform what the Tru delivered, with better build quality and easier cleaning to boot.

The biggest difference is in the burr quality. Modern budget grinders use better-machined burrs with tighter tolerances. The Tru's burrs were functional but rough around the edges, literally. Small imperfections in the cutting surfaces created those extra fines that muddied up the cup.

Common Problems and Fixes

If you own a Tru grinder and it's acting up, here are the most common issues I've seen.

Grinding Slows Down or Stalls

Coffee oils and fine particles build up between the burrs over time. The fix is simple: remove the top burr (usually held in place by a twist-lock mechanism), brush out all the residue with a stiff brush or old toothbrush, and reassemble. Do this every 2-3 weeks if you grind daily.

Inconsistent Grind Size

If your grind suddenly gets more inconsistent, the burrs may be wearing down. Unfortunately, replacement burrs for the Tru are almost impossible to find since the brand is largely defunct. This is usually the end of the road for the grinder.

Static Cling

The Tru grinder, like many budget models, generates a lot of static. Grounds stick to the catch container, the chute, and everything else nearby. A quick fix is to add a single drop of water to your beans before grinding (the Ross Droplet Technique). This kills the static without affecting your coffee.

Loud Motor Noise

These grinders were never quiet, but if the motor noise increases over time, it usually means coffee has worked its way into the motor housing. A thorough cleaning helps, but there's no easy way to access the motor internals on most Tru models.

Should You Still Use Your Tru Grinder?

If you already own one and it's working fine, there's no reason to throw it away. It beats a blade grinder for drip coffee, and it's perfectly acceptable for casual coffee drinking where you're not obsessing over extraction percentages.

But if you're looking to upgrade or if your Tru is on its last legs, I wouldn't recommend trying to find another one. The money is better spent on a current-production grinder with available parts and better grind quality. Check out the Best Burr Grinder roundup for options that start around $50 and offer a clear step up in every category.

The tipping point is usually when you start brewing manually. The moment you switch from a drip machine to a pour-over or French press, grind consistency becomes much more noticeable in the cup. That's when the Tru's limitations start showing up clearly.

Is a Conical Burr Grinder Always Better Than a Blade Grinder?

Yes, always. Even a budget conical burr grinder like the Tru produces more uniform particles than any blade grinder. Blade grinders have no mechanism for controlling particle size. They just spin a blade and chop whatever is in the chamber. Some beans get pulverized into dust while others stay in large chunks.

A conical burr grinder, even a cheap one, forces beans through a gap between two burrs. The gap size determines the particle size. It's not perfect on budget models, but it's a fundamentally better approach to grinding coffee. If you're currently using a blade grinder and considering a Tru or any other burr grinder, make the switch. You'll taste the difference immediately.

FAQ

Where can I buy a Tru conical burr coffee grinder?

New Tru grinders are very difficult to find since the brand has been discontinued from most retailers. Your best bet is secondhand marketplaces like eBay, Facebook Marketplace, or thrift stores. That said, for the same price you'd pay for a used Tru, you could get a new budget burr grinder with a warranty and available replacement parts.

Can the Tru grinder work for cold brew?

Yes, and this might actually be its best use case. Cold brew is very forgiving with grind consistency because the long steep time (12-24 hours) and cold water extract flavors slowly and evenly. A coarse grind from the Tru works fine here, even with the extra fines mixed in.

How long do the burrs last on a Tru grinder?

Expect the burrs to deliver acceptable performance for about 300-500 pounds of coffee with regular cleaning. For someone grinding 30 grams per day, that translates to roughly 3-5 years. You'll notice increasing fines and slower grinding as the burrs wear down.

Is it worth repairing a broken Tru grinder?

In most cases, no. The cost of sourcing parts (if you can find them) and the labor involved usually exceeds the price of a new budget grinder. If the motor dies or the burrs are shot, put the money toward a replacement instead.

Final Thoughts

The Tru conical burr grinder was a solid entry point for people who wanted better coffee without spending a lot. It did its job for basic drip brewing and introduced a lot of people to the idea that grind consistency matters. If yours is still running, keep using it for drip coffee and cold brew. When it's time to replace it, step up to something in the $60-100 range where you'll get noticeably better grind quality, actual parts support, and a grinder that can handle more brewing methods.
