Cuisinart Custom Grind & Brew Single-Cup Coffee Maker Review: DGB-30

The DGB-30 is for people who want fresh-ground coffee one cup at a time and have a few minutes to spare in the morning. It is a poor fit if your routine depends on a grab-and-go pod machine. We scored it on three things: how the coffee tastes, how hot it arrives, and how much work it adds to a weekday morning.

The DGB-30 combines a stainless conical burr grinder with automatic grind-to-basket brewing. It uses a gold-tone permanent filter, and it also takes a 4-cup basket paper filter if you prefer paper. A charcoal water filter, refill and cleaning indicators, and an adjustable tray round out the feature list.

Cup sizes, controls, and counter space

Controls are limited on purpose. Mild, Medium, and Bold set strength for hot whole-bean brewing. Ground bypasses the grinder, and Ice works with beans or grounds. Strength cannot be chosen in Ice or Ground mode. At 15.71 inches tall, the body occupies noticeably more counter space than a typical small pod machine, so measure your cabinet clearance before you buy.

Whole beans, ground coffee, and pod compatibility

Whole beans and pre-ground coffee both work. The DGB-30 is a basket-style drip brewer, so there is no K-Cup holder, no espresso system, and no steam wand. If pods matter to you, this is not the machine.

Grind control and brewing workflow

Setup was straightforward, and so is the routine. The Cuisinart manual describes a preset medium grind, and the strength setting changes the dose rather than the grind size. That means you will not dial in burr spacing the way you would on a standalone grinder. Some listing copy promises an adjustable grind, but we would not buy the machine expecting it.

The workflow is simple. Fill the hopper, pick a size and strength, and press start. Afterward you open the basket door, discard the grounds, and close it securely. An interlock stops the machine from brewing if the basket or door is not seated correctly.

The hands-on lesson here is about pace. The drip phase can feel slow when a fast grab-and-go drink is the priority, so the DGB-30 rewards a slower morning.

Noise, mess, and refill frequency

Brewing releases conspicuous steam above the machine, so keep it out from under low cabinets. Bean jams can also interrupt a brew, and recovering from one means paying attention to the grind-filter position. We do not have a verified decibel figure for the DGB-30, so we will not quote one.

Refill frequency depends on how many cups you pour, how strong you brew, and how much water the tank holds. Cuisinart lists a 58-ounce tank, though some retail copy gives different figures, so treat the official number as your guide. The 8-ounce bean hopper is large enough that you can leave beans in it between brews.

Flavor and strength

Fresh grinding is the reason to buy this machine. The hot cup has a rich, robust character. Strength comes from dose, so Bold gives a fuller cup and Mild a lighter one. Because you cannot change the grind size, choose beans that suit a medium grind.

How hot does the coffee get?

The coffee reaches the cup very hot, which is the answer most buyers want. We have no verified temperature reading, so we will not quote a number.

Over-ice brewing

Ice mode brews roughly half the hot volume you selected, concentrated to be poured over ice. It is hot coffee brewed for ice, not cold brew. Our finding was that the over-ice cup retains flavor after the ice melts and does not taste washed out right away. That makes it a real reason to pick this machine for summer mornings.

Cleaning after each brew

The daily chore is the one that decides whether you keep using the machine. Emptying and rinsing the used-coffee basket adds a recurring task to each cup, and that is where the DGB-30 loses to a pod machine. You do not need to wash the entire grinder every day. Discarding the grounds and rinsing the basket covers the daily routine.

Grinder care and descaling

The manual calls for a brush on the ground outlet, and unplugging before any disassembly. The hopper and burr come out for cleaning, and washed components should dry thoroughly before reassembly. Descale monthly, or sooner if your water is hard, and follow the CLEAN indicator. Grinder cleaning takes more effort than disposing of a pod, so budget a few minutes for it.

Where the DGB-30 earns its place

The very hot, rich cup, the simple controls, and the over-ice cup that keeps its flavor as the ice melts are the three things we would point a friend to. Setup is straightforward, and nothing about the first brew needs the manual.

Trade-offs and what we cannot tell you

The weak spots are the ones we have already covered: the grounds-basket chore, the footprint, the steam, the slow drip phase, and the occasional bean jam. What we cannot tell you is how long a DGB-30 lasts. We have no failure-rate data, and the Limited 3-year warranty is the only durability assurance we can point to.

DGB-30 vs. DGB-2

The DGB-2 is the older Cuisinart Grind & Brew single-serve. It grinds into a reusable cup that you move to the brew head by hand, and it takes K-Cup pods. Grinding and transferring that cup can scatter grounds over the tray and counter. The DGB-30 grinds directly into its brew basket, offers six sizes against three, and adds a dedicated Ice mode.

The original black DGB-2 is marked discontinued on the manufacturer site, so retail availability varies. Some DGB-2 units stop brewing while the grinder keeps running, while others run for years, so early failure is a risk, not a certainty.

Pod machine or separate grinder and brewer?

Choose a pod machine if speed and zero cleanup matter most. Choose a separate grinder and a drip brewer if you want to control grind size, since the DGB-30 gives you a preset grind. The DGB-30 sits in between: fresher than pods, simpler than two appliances, and less flexible than either. If you find the DGB-30 sold out or too tall for your cabinets, the DGB-2 is the fallback, with the messier workflow described above.
