Presto 02937 Dorothy™ Electric Rapid Cold Brewer - Cold brew at home in 15 minutes - No more waiting 12 to 24 hours.

I will start out by saying that I've been making my own cold brew for approximately 2 years now. Prior to this, I was "wasting" a lot of money buying cold brew on a nearly daily basis. I love a cold glass of cold brew in the summer after dinner. It's usually my dessert! I also love the taste of coffee, and I only add a little milk (sometimes half/half) to my cold brew, no sweetener.I have been more than happy with my County Line Mason Jar cold brew maker. I've had it for two years and never once had coffee grounds in my finish product. It makes an extremely strong cold brew. Only downfall is the 14 plus hours to make it! There have been many of nights that I wanted to kick myself for forgetting to make it when it ran out! Enter the "Dorothy"! What a fantastic idea, I thought. I wondered if it would work. I read through the reviews, and depending on what you want to believe, some say yes, other said no. Here is MY opinion after using this for about a month now.It does work! I can say that what I've made in this rapid brewer has tasted fantastic, and I have not had any grounds in my finished product (although it can be a bit cloudy/silt). I think that silt is a problem more with the French Press, which this is like! I have never had an issue getting the "tornado", or whirlpool to form. I can say that when using filtered refrigerator water that you will have to double (possibly triple) the amount of time needed to make the coffee as strong as you would with room temperature water. I have also noticed a difference in cold brew strength depending on how fast the coffee is introduced to the "tornado". The instructions say to add the coffee slowly, so definitely do that! I have now been filling the carafe slightly below the max line (using refrigerated water), using 2/3 cup of coffee grinds (store purchased, but not freshly ground), and running this for an hour. I've gotten into the habit of starting this process while I'm cooking dinner. Bottom line here is that I don't think you can obtain "concentrate strength" cold brew with the Dorothy, but filled close to the max will give you more than enough for two large glasses of cold brew. And it will still taste as good (more coffee, less milk/creamer) in the rapid brewer. As long as the instructions are followed, I don't find it "watered down" at all, as some reviews have stated. My last batch was quite strong (1 hour spinning). Deviating from the instructions (like when I just dumped the entire 2/3 cup of coffee in at once), and you might experience different results.My biggest knock on this product would be the fragile glass carafe. Be careful!! I actually broke the first one in a week (my mistake, as it was bumped off the counter). I can't say that any glass would have survived that fall on a wooden floor. To order a replacement carafe from Presto would be $20, plus $9 shipping, so I bought another new Dorothy for $35 (Prime, no shipping). Now I have spare parts. But this carafe feels very fragile and I use extreme caution even washing it (I hand wash all parts even through it states that it is dishwasher safe). That brings me to my second criticism, cleaning the Dorothy. Let's just say it is messy! Coffee grinds all over the place trying to get the press part/plunger off of the stirring cup. I've learned to use a plastic bag (grocery store bag or bread bag) and place the plunger, with stirring cup still attached, in the bag and release the stirring cup from the plunger (which once you know how, it's easy to release) all in the bag. Yes you have some liquid in the bag, but this keeps most of the grounds from going down into the plumbing. I just have a paper towel or two in the bag to absorb the liquid.I enjoy having fresh cold brew that I can make relatively quick, so for that, I recommend the Dorothy. I will continue to use my old cold brew maker, but definitely have room in my kitchen for the Dorothy! My daughter also thinks it's so cool to watch, and she doesn't drink cold brew, but offers to make it for me!! Bonus!

I ordered this product again because I had given my previous one to family member. Love the product. However when I received the product the glass was broken pieces. I called customer service and within 4 days received a replacement. I've used it almost every day since I have gotten this. At least 10 times. Highly recommend.

I used this over twenty time with perfect results. One time I had a hard time pulling out the bottom piece after brewing and it was stuck. The carafe broke while trying to remove it. You can get a new one direct from Presto web site.

So far this works without a hitch. I will say, it’s somewhat loud. The sound of it spinning and then the water sloshing. Not really a pleasant sound. I am currently brewing for first time. Will update after it completes.UPDATE: Worked perfectly. Follow the directions. You absolutely must wait the 5 min or longer before plunging or you will have the water and grounds burst upwards out of the carafe. It has too much pressure and needs to settle. Once you wait, it will push down smooth with ease and no resistance! Pour your coffee and call it wallah!! Grounds in the carafe and coffee in your cup, ground free! I let mine brew the 20 min. I feel like its the perfect black coffee cup level strength and I don’t like really weak coffee. Again that is only with 1/2 grounds, not the 2/3 it recommends. You can do the 2/3 and then even brew longer if you want it STRONNGG.

I just made a batch with cold, filtered refrigerator water (They suggest double brew time for cold water), and it was so smooth and delicious. I find it smoother than cold brew that sits in the fridge overnight. First use, so we'll see how it turns out longevity wise, but so far very happy with it.*follow up. My only complaint is that it's kind of a pain to clean.
