OVALWARE Airtight Cold Brew Coffee Maker with Tea Infuser & Spout 1.5L/51oz

Brewing smooth coffee concentrate at home gets significantly simpler with the OVALWARE 1.5L Cold Brew Coffee Maker, a dedicated cold brew coffee maker designed to sit neatly inside standard refrigerator shelving. Instead of dealing with messy paper filters or awkward strainers, you simply add coarse coffee grounds into the interior core, fill the pitcher with water, and let it steep. The cold brewing approach produces coffee that is 70 percent less acidic than traditional hot brewing, yielding a rich concentrate that you can store and mix with water, milk, or ice whenever you want a drink.

Material quality stands out across the entire design. The main body is built from extra-thick, lab-tested borosilicate glass, which provides strong resistance to temperature changes. Inside, the brewing core uses an 18/8 rust-free superfine laser-cut filter paired with a medical-grade stainless steel filter and lid cap. This fine mesh keeps sediment from escaping into your finished batch while allowing water to circulate thoroughly around your grounds. A BPA-free silicone seal keeps the container completely airtight, locking in flavor and freshness for up to two weeks in the fridge.

Daily handling is straightforward thanks to thoughtful physical touches. An integrated, easy-access handle gives you a confident grip when lifting the pitcher from a crowded shelf, and the built-in pouring spout controls the flow to avoid accidental spills. A removable non-slip rubber cushion base wraps around the bottom of the pitcher, adding protection when setting the glass down on hard kitchen counters. In addition to coffee, the infuser handles loose-leaf tea and tea bags, and the heat-resistant glass allows you to brew hot tea like a traditional teapot just as easily as steeping iced tea in the refrigerator.

As with any glass steeping setup, there are practical considerations to keep in mind. You need to use a coarse grind size to ensure proper extraction without clogging the fine laser-cut perforations. While the pitcher is engineered to fit within standard fridge shelves, its 1.5-liter capacity means it takes up meaningful vertical space. Because it relies on passive steeping rather than rapid electric heating, you also need to plan ahead and allow sufficient time for your cold brew concentrate or chilled tea to develop before serving.

Verdict: The OVALWARE 1.5L pitcher is an outstanding choice for iced coffee fans and tea drinkers who want to prep large, low-acid batches for the week ahead. If you need a quick single cup in minutes or prefer an automated electric appliance, look elsewhere, but for pure simplicity and dependable airtight storage, this pitcher delivers.

• Capacity: 1.5 liters (51 ounces)
• Carafe Material: Extra-thick borosilicate glass
• Filter Material: 18/8 rust-free superfine laser cut medical-grade stainless steel
• Seal Material: BPA-free silicone
• Base: Non-slip rubber cushion

A great fit if you:

• Want to make smooth, low-acid coffee concentrate at home and store it fresh for up to two weeks.
• Enjoy both cold brew coffee and hot or iced tea, and prefer using a single pitcher for both.
• Need a dishwasher safe brewer made with stainless steel, silicone, and durable borosilicate glass.
• Like to prep up to 1.5 liters of concentrate in advance to pour throughout a busy work week.

Consider something else if you:

• Need an electric, rapid-brew machine that prepares a hot cup of coffee in under two minutes.
• Prefer an unbreakable stainless steel or plastic travel container designed specifically for rough outdoor transit.
• Only brew single servings at a time and lack the refrigerator shelf height for a 51-ounce pitcher.

Confirm on the listing:

• Check the exact physical height and diameter to ensure it fits comfortably upright on your refrigerator shelves.
• Verify whether your coffee grinder can produce a coarse grind setting, which is recommended for the laser-cut filter.
• Review the specific replacement parts availability, such as spare silicone seals, if you plan on heavy daily use.
• Check the included packaging details to see if cleaning brushes or recipe guides are provided alongside the infuser.

How to compare your options: When evaluating cold brew pitchers, focus on filter construction, container materials, and lid sealing capability. This model provides an airtight BPA-free silicone seal paired with medical-grade stainless steel and borosilicate glass, which ensures your concentrate stays fresh for up to two weeks without absorbing stray refrigerator odors. Its ability to brew both hot and cold beverages in the same vessel also offers versatility that basic single-use plastic pitchers cannot match.

• Always stick to a coarse grind size for your coffee beans to prevent fine particles from passing through the laser-cut stainless steel mesh.
• Ensure the BPA-free silicone gasket is seated evenly along the lid cap before storing the pitcher to maintain an airtight seal in the fridge.
• When switching from cold brew coffee to delicate loose-leaf teas, wash the pitcher and filter thoroughly in the dishwasher to keep flavors pure.
• Keep the non-slip rubber cushion base attached to the bottom of the borosilicate carafe whenever placing it on stone, tile, or granite countertops.
• Pour your finished concentrate slowly using the built-in spout and easy-access handle, diluting it with cold water, milk, or ice to taste.
