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 just made my first pot of cold brew with this unit. Aaaaaaabsolutely delicious. I poured a tall glass on ice, added a splash of milk, one heaping teaspoon of Allulose, and a dash of vanilla. Super refreshing for this record breaking hot day. I recommend to those who are considering purchasing this unit to carefully read the instructions over prior to making the coffee, then again as you go. They are easy to follow. If you do, you'll have a delicious carafe of cold brew practically toute de suite.One batch easily fills three tall glasses on ice, so basically with one use, you've already broke even with the cost of two similar cold brews at a cafe.

I liked this so much I bought a second one, and I make them both at the same time and save the coffee in the fridge, rather than making it every day. I let it spin for about 30 minutes as I like my coffee strong enough to handle adding creamer without losing the taste of the coffee. I have used them for about 3 years now. The motor shorted out in one of them, sadly, but my husband was able to replace the motor cheaply (not a Presto replacement, he just bought a motor). And... I broke a carafe because the glass is pretty thin. Pro-tip: when you pull the plunger/grounds basket out, there is a lot of suction. Hold the carafe firmly pressed against a counter or your sink so that it doesn't jerk when the plunger releases and you slam into something like a dumb-dumb. Otherwise, these have been a godsend as I don't like making or drinking drip coffee. It's about as easy as a french press, just takes a little while because you have to let it spin for a bit. When I bought mine, they were $30, and now they are selling for half that- well worth it! In fact, it's cheaper to buy one of them than it would be to buy a replacement carafe so I'm about to have a THIRD base as I buy it *again* lol.

A little extra prep, makes a better tasting cup. I love this! Even cheaper coffee brands taste decent. Albeit, I'm using bottled water only. Great price! I hit a sale & they even paid shipping.It's designed like a French press, except uses cold water. The electric base creates cyclonic action, to stir the cold brew. This action decreases normal cold brewing time, from hours to 20 minutes; let it swirl five minutes longer, for stronger flavor. ingenious design with the magnetic coffee basket. So far, no complaints, no problems. It makes roughly 2 cups; ideal for a single coffee lover wanting a second cup later. I refrigerate the unused portion. If you want it warm, it tastes great when warmed in microwave too.I've experimented with different grinds.The downside: using recommended courser grind, requires using more coffee to brew (2/3 cup) than what a drip maker (using hot water) does with same measurement.Wish the carafe handle was a little sturdier. I'm going to safeguard mine using foam on handle. Glass isn't very thick; use care when rinsing carafe in the sink, removing the press (with basket attached) or placing on a stone counter. A full carafe is surprisingly heavy! IMO, Carafe needs to be made with thicker glass. Otherwise great product.

This is probably the worst product I've ever ordered from Amazon. I followed the instructions to the letter, and when it came time to push the plunger, the whole carafe shattered, with coffee and grounds everywhere including all over me. This product is dangerous. Do not purchase.

I was excited to try the Dorothy for the fast pinch making cold brew when i didn't plan ahead for a 24 hour soak. I followed the instructions and made my first batch right away. Although it wasn't bad, it definitely wasn't great either. The coffee wasn't as smooth in flavor as the 24 hour brew time, it was a little 'rough around the edges'. It seemed gritty and underwhelming. The coffee also just looked like dark water, not coffe. I won't be keeping it, I have it in my donation pile not worth returning for $11.
