Berlinzo Ice Ball Maker Mold, 2 Clear 2.4in Whiskey Spheres Review (2026)

What this product is

This is a two piece ice ball maker from Berlinzo that produces two clear 2.4 inch ice spheres per freeze cycle, sized to sit in a standard rocks glass for whiskey or other spirits on the rocks. According to Berlinzo's own product page, the kit includes a silicone mold, an outer tray that acts as a water storage box, and a manual, and it works by directional freezing, where water freezes from the top down so that trapped air and impurities are pushed into a separate reservoir rather than staying in the ice itself. The company lists overall mold dimensions of about 7.2 by 4.9 by 7.4 inches.

Fit for the job

For anyone who wants restaurant style clear ice at home without spending on a dedicated ice press, this mold does the core job of producing genuinely clear rather than cloudy spheres. Two spheres per batch is enough for a solo nightcap or a drink for two, but it does mean you need to freeze ahead if you are hosting more than a couple of people, since the mold only runs one cycle at a time. Berlinzo also sells an optional storage bag that holds a batch of finished spheres, which is the practical way to build up a supply before a party rather than relying on the mold alone.

Features and specs

The process, per the manufacturer's instructions, starts with filling the water storage box with room temperature water to a marked line, pressing the silicone mold down into it, and freezing for roughly 20 to 24 hours at typical freezer temperatures. This slow directional freeze is what produces the clarity, as opposed to a standard silicone tray that freezes from all sides and traps cloudy air bubbles in the center. Berlinzo states the mold is BPA free silicone, and releasing the finished sphere is done with a short rinse of warm water over the base rather than forcing it out, which helps avoid cracking a mostly clear sphere.

Build and materials

The mold itself is BPA free silicone paired with a plastic outer tray that holds the freezing water, based on the brand's own description. Because clear ice depends on a slow, controlled freeze, this is not a fast turnaround accessory, and results can vary somewhat with your freezer's temperature consistency and the water you use. The 2.4 inch sphere size is built to fit comfortably in most standard rocks glasses without overflowing them, and the slower melt rate of a large sphere compared with regular cubes is the main reason spirits drinkers reach for this style of ice in the first place.

Who should buy it

This suits someone who drinks whiskey or other spirits on the rocks regularly and cares about presentation and slower dilution more than speed or bulk output. It is a lower cost entry point into clear ice compared with a standalone directional freezing ice chest, though it asks for more patience since you are limited to two spheres per roughly day long freeze. If you regularly host groups and need many spheres at once, a larger multi cavity mold, like a stackable six pack style tray, will get you further per freeze cycle even if the resulting ice may be less consistently clear than this smaller batch approach.
