Berlinzo Premium Clear Ice Ball Maker Mold - 8 Large 2.4" Crystal Clear Ice Balls for Whiskey, Cocktails & Bourbon - Easy-to-Remove Mold for Ice Spheres - XL Storage Bag Included (Non-Electric)

I was really intrigued by the concept of "clear" ice. I was accustomed to standard ice cube trays - put the water in and tomorrow you've got ice. But the ice was filled at the bottom of the cube with air bubbles, and it melted fast. I started hearing about clear ice makers - no air bubbles at all, and the ice lasted much longer. I was curious if that claim was really true, and if so, how do they work? So I did some research and learned of the basic principles. Large bodies of fresh water like lakes and slower moving river in northern regions will freeze over each winter. They freeze from the surface downward, and that's the key - water freezing top - down like that forces air and impurities down as it freezes, leaving a layer of clear ice over the unfrozen water below. These home clear ice makers operate on the same principle; water is placed into an insulated container - a cooler, if you will. Silicone molds are inserted at the top of the cooler. These molds have holes placed at the top and bottom to allow for both complete filling and the free movement of water between the tank below and the molds. The molds must also be filled with water to the top. Put the device in your freezer. The freezing process begins at the top of the molds and moves downward, forcing air and impurities through the holes at the bottom into the insulated tank below. Leave the device in your freezer at least 24 hours (my 5 cubic foot freezer operates at -3° F, and it takes 28 hours for this device to freeze thoroughly). Taking the ice out of the molds reveals crystal clear ice spheres, exactly as promised. Removing the molds is a bit of a chore, but the design of this device - thick, strong handles at each end of the individual molds makes removal surprisingly easy, as long as you're patient and don't try to use too much force. The included storage bag easily holds about a dozen spheres, but with careful packing I've gotten 16 spheres in there. Some notes on what else I learned during my research: - The embedded air bubbles are the chief reason ice sitting in a liquid melt down so quickly - as the outer layer melts the warmer liquid will infiltrate into those bubbles, hastening the process. Clear ice has no embedded air, so the warmer liquid can't get to the interior sections. - It's the surface area of ice that melts. Square cubes have more surface area than spheres, so spheres will melt more slowly than square cubes. - Harvested spheres (or cubes) will crack if you take them directly from the freezer and immerse them in liquid. The ice should be 'tempered' (left to sit at room temperature) for 10 to 15 minutes before immersion. - Water quality makes a difference, particularly in the tank below the molds. Dispersed minerals and other impurities will wind up at the bottom of this ice, possibly giving it an unpleasant taste or smell. Not an issue if you plan to use this ice for chilling bottles or cans, but it could give unpleasant results if used in consumables. Water from reverse osmosis filtration or distilled water would work fine if you want to use the tank ice in consumables, as well as making for excellent molded clear ice. Of course you can simply discard the tank water, or use it (after it warms to room temperature) to water plants. I try not to waste the tank water, and my plants appreciate it. - This device produces 2.5-inch spheres; ensure your glasses will accommodate spheres this large. - The 8-sphere device is large and will take up significant space in a refrigerator freezer. The smaller units for 2 or four spheres/cubes would work better there.

Worth every penny! If you enjoy your drink and appreciate a cristal clear ice, this is the way to go. Easy to extract always perfect. It is a little bulky but it is what the system demands for great results. Sturdy and perfectly made.

A device that does exactly what it is supposed to do and does it extremely well!!! I am obsessed with making the correct ice for cocktails in my home bar. Berlinzo makes the only products that work as advertised that I have been able to find. This makes perfect ice balls, crystal clear and does it quickly. The spear ice maker takes about 15 more hours of freezer time and the spears are not perfect but good, the ice balls from this device are spectacular!!!

The Tinana and Berlinzo are essentially the same ice maker with two different labels. But there are some differences between the two, and to my mind, they do not favor the nearly twice as expensive Berlinzo: 1. Physically, they are 98% identical. The only physical difference between these is that the Berlinzo is sheathed in a hard plastic outer casing with a satin black finish and some small, but nice, graphics. Between the two, this gives the Berlinzo a more “formal” and “classy” appearance. Seriously, it looks nice. If that matters to you, while it sits in your freezer, then it’s your ice maker of choice. Or, perhaps you want to give one of these as a gift; the Berlinzo does look nicer. [FWIW, their exterior shipping boxes are both nice, but to my mind, the Tinana is nicer in its simplicity.] Other than the Berlinzo’s outer shell, they are identical, and their parts are interchangeable. However, I think this outer shell contributes to difference #2. 2. Per their instructions, the Tinana should be allowed to freeze for 30 hours, while the Berlinzo requires 40-48. If you’re on any kind of clock, that’s significant. Other than the thin satin plastic shell on the Berlinzo, I can think of no reason why the two devices should have such significantly different freezing times. Interestingly, the Berlinzo instructions specifically state that you should not freeze it for more than 50 hours, else there is a risk of cracking the shell. That strikes me as a disadvantage, or at least a risk of disadvantage. I found the freezing times for both devices accurate. 3. The Berlinzo comes with a nice plastic bag in which to store your spheres. Unfortunately, it’s not really big enough to hold more than one batch at a time. Ziplock is your friend here. 4. In all other respects, the two devices produce identical, almost entirely clear ice spheres when you follow the instructed times for freezing. And if you don’t, they also perform similarly. Pulling either device out of the freezer six hours ahead of time will reveal a not-fully-frozen base, and partially formed (about 75%) spheres. Also, if you decide to use warm or even hot water to slow the freezing process further, you’ll need to adjust your freezing time accordingly. I do, and have found an additional six hours (for a total of 36) in the Tinana works well, while the Berlinzo requires its full 48. 5. The spheres from both devices also benefit from tempering. Without tempering, they didn’t always crack, but they did sometimes. And with tempering, none of the spheres cracked when room temperature whiskey was poured on them. Most people recommend five minutes for tempering, and that makes sense if the spheres are kept in an ice bucket or bowl. I found that when placed in individual glasses, 2-3 minutes seemed sufficient to avoid cracking. YMMV. I have attached pics showing the spheres side-by-side. They are indistinguishable. I also did a 90-minute melting test, with images taken at 00:00, 00:30, 01:00, and 01:30, with a sphere from each maker in a glass containing 2 ounces of water. Granted, water and booze are not the same thing, and holding a glass will speed the ice melting process. But all I wanted to do was compare how a sphere from each maker would perform in the same environment. Short answer: they melted identically. And that’s no surprise since they are almost identical in their construction, and entirely identical in their method. For me, the performance of both the Berlinzo and the Tinana are 5 stars, with the Berlinzo docked one star for value and the additional 10-18 hours of freezing time. With respect to some of the less positive reviews: 1. Yes, it’s difficult to remove the rubber molds from the freezing box. It gets easier after first use, but they’re tight for a reason. I’m older, and my finger strength isn’t what it used to be, but I managed to get everything apart. 2. It’s not difficult to fill the container or to get the molds topped up. A gooseneck kettle is handy for topping off. 3. There is occasionally a little bit of excess ice around the seams (see pics), but it comes off easily. 4. Depending on your water minerality, you may find you get better results by boiling the water first, filtering it with a real filter (Brita doesn’t cut it), etc. Distilled or RO/DI water doesn’t always produce more clarity. The people who make the OnTheRocks version of this (I use their box for cubes) have some videos with recommendations for “fine-tuning” your ice. We have off-the-charts hard water in our house, and a whole house softener that reduces, but does not eliminate, the hardness. The tap water produced quite acceptable ice spheres. 5. With respect to water “wastage,” don’t rinse that ice block down the drain. Let it thaw and use it to water plants or pets or whatever. It’s perfectly clean water. It’s only waste if you waste it. Don’t throw it away!

As a cocktail enthusiast, I was excited to try out this ice ball maker, and I'm pleased to say it didn't disappoint. This simple yet effective device has quickly become an essential tool in my home bar setup. The ice ball maker is incredibly easy to use. Just fill it with water, close the mold, and pop it in the freezer. In a few hours, you have perfectly formed ice spheres ready to enhance your favorite drinks. What sets this ice ball maker apart is the quality of the ice it produces. The spheres are crystal clear and perfectly round, adding a touch of sophistication to any glass. Not only do they look impressive, but they also serve a practical purpose. The large surface area of the sphere melts more slowly than traditional ice cubes, keeping your drink cooler for longer without diluting it as quickly. The mold is made of durable, food-grade silicone that's both flexible and sturdy. This makes it easy to remove the ice balls once they're frozen, and ensures the mold will last for many uses. One minor drawback is that it only makes a limited number of ice balls at a time, so you'll need to plan ahead if you're entertaining a crowd. However, for personal use or small gatherings, it's perfect. In terms of maintenance, the ice ball maker is dishwasher safe, making cleanup a breeze. Overall, this ice ball maker is a fantastic addition to any home bar. It's easy to use, produces high-quality results, and adds a touch of elegance to your drinks. Whether you're a cocktail connoisseur or just someone who appreciates a well-presented beverage, this ice ball maker is definitely worth considering.

The Berlinzo clear ice ball maker is totally awesome and a great conversation starter. The process takes approximately 24 hours to be completed, but once done you have 2 crystal clear ice balls, and two nicely formed ice squares in the base of the unit itself. The unit itself in very durable and flexible. To separate the base of the unit from the water reservoir can be a little tricky, after removing the ice balls I turned the unit upside down and run a butter knife underneath the lip on the reservoir and the base to break the seal in order to remove the two nicely sized ice squares in the base of the unit. I think it was a good price and I would highly recommend purchasing one.

The invention of the automatic ice maker is a godsend in my book. Though it gets boring when you have the same old ice maker machine ice for when you want an ice-cold drink in a nice glass. And then, in steps the Berlinzo Clear Ice Ball Maker Mold, and you have fancy-dancy ice balls for your fancy drinks. While it is not automatic, you have to fill this mold and its holder with water, then place it in the freezer for up to 24 hours, indeed it works. My first Ice Ball was terrific, now my second one was not so great, but that was my fault, as I did not dump the ice that formed in the base of the holder out and start fresh with all water. Not sure why, but I see in other comments on the page that it needs to breathe. It was an easy process, to clean the mold and holder when I took it out of the box, filled the holder with water, inserted the mold into the holder, and placed it in my freezer. Just make sure you have room in your freezer for the holder, it is a tad bulky. The next day I took it out, opened it up and there was a perfect ice ball. I have read some comments that the ice did not come out clear, for me it did, using only Washington DC City tap water. I wonder if I use fancy bottled water if the ice will be even better. The only downside I see is it makes one ice ball at a time, and it takes 24 hours. Fine if you want to drink alone or are thinking far enough ahead that you take several days to make several ice balls for drinks with friends. Though I see on their site they have a two-ice ball mold set up as well. For now, I will continue to make one ice ball a day and put the ice ball in my freezer ice storage bucket. I took several out that I made day after day, and they were all just fine. I am pleased with the ease of use, the quality of materials, and the finished product that the mold makes. I like its well-designed packaging, and the shipping on Amazon was quick and no hassle. This is a great housewarming gift, or general gift, for a friend who likes to make nice drinks. You don’t have to drink alcohol to have a nice-looking drink with ice in it, it will be great for an Arnold Palmer-style drink. I think kids will get a kick out of these ice balls in their drinks too, it will make them feel so grown up. I am looking forward to making a bunch of ice balls and having them stacked up in a glass ice container for a future event. I think you will enjoy this product as much as I have, and am going to this fancy-dancy drink season!

Hard to get ice out of mold. The ice is amazingly clear when you empty the molds and container completely of all ice. If you leave the frozen blocks in the bottom, ice isnt clear. It’s really hard to get the blocks in the bottom out… I have to run hot water over it for a long time to get the blocks to release… over all, the ice balls are beautiful if done right.
