Bunn machines, like the ICBT or axiom use a digital controller to brew on bursts, let say put water, wait 15 seconds, add water again wait again and so on. That way we can decide for how long the water is in contact with the coffee. Fast brewing makes weak coffee, slow brewing extracts more coffee. That's what makes those machine more expensive, you control more variables, like temperature, water bypass, and obviously size of the batch. About starbucks being better on your stomach is not going to be the machine, but the acidity. Some coffees acid, I would say try darker coffees for less acidity. Some coffees like Mexicans or nicaraguans are less acidic. Light roasts are very acidic. Answer from guanacazo on reddit.com

r/Coffee on Reddit: Why are commercial coffee machines (ie. Bunn) such as the ones in starbucks so expensive? And do they utilize an altogether different brewing mechanism? I am hoping to find something similar at a more reasonable price point
November 19, 2019 -

I am curious to know if anyone is familiar with these types of coffee machines and can shed some light on what it is they do differently and if they utilize a standard drip brewing approach. or something completely different?

https://commercial.bunn.com/33600.0029

I have ulcerative colitis and when I make coffee at home with a standard drip machine it gives me such bad inflammation even when I use the same beans I get from starbucks. When I get the coffee at starbucks, I tolerate it so well and it makes a tremendous difference in my quality of life. I really am curious to know what it is that makes these machines different from the rest. It would be so appreciated if anyone knowledgeable on them could chime in.

They both do and don't do a lot different - because all home machines also do things different from one another in very similar fashions. How much water is used, how it's distributed across the coffee, the intervals between portions of water being added ... all of these things can make subtle differences in brewing the coffee. But none of those should make a difference with your colitis. They're not extracting anything different and as far as I know, there's nothing within "over" extraction that's particularly upsetting, or anything missing in "under" extraction that would be be similar - doing a different or sometimes better job of the same brew shouldn't matter as far as your digestive tract. You may be making your coffee at home stronger than Starbucks does in store, it is very common for home consumers to use a higher coffee:water ratio in their home machine than somewhere like Starbucks does. Most of what makes those machines so expensive is durability and pace. They're designed to remain functional over 1000s of brews because that's a typical week for them, where a home machine would take several years to put on that kind of milage. Similarly, a commercial machine needs to be capable of making back-to-back pots or similar, so needs a much better heat management system and a much beefier power supply - which turns into a more expensive electical safety system and certification.

Less expensive and therefore made with cheaper components. The A10 Model will hold up to use in Police Department Squad rooms and Fire House kitchens. I know this from personal experience.

January 9, 2024 - Theyโ€™re so fast you can easily wait for a brew cycle to finish. BUNN machines also donโ€™t let you adjust the water temperature, coffee strength, or bloom phase (3). Theyโ€™re designed to brew one style of coffee and do it well. If thatโ€™s not what youโ€™re after, take a look at our other picks for the best drip coffee makers. BUNN coffee makers are an investment. Theyโ€™re not outrageously expensive, but they certainly arenโ€™t the cheapest on the market.

September 21, 2013 - So, after some research, I decided to give the BUNN a shot. I was a little apprehensive about spending $100.00 on a coffeemaker, but I figured I like coffee well-enough now to justify the purchase, especially if it lasts a while. It was $99.00 at Wal-Mart. It can be found slightly cheaper on Amazon, I think. There are other versions that BUNN sells that have updated styling, for slightly more money.

First New Coffeemaker in 9 Years! | BobIsTheOilGuy
October 17, 2023 - It uses basket filters (so it has to be very even) I've had 2 behmor coffee roasters.. their products do not last well but they pretty much have the entire market for a decent under 500$ coffee roaster. My only concerns with their coffee maker would be durability over time. I am sure it makes an excellent cup. The bunn is only good for full pots and you really should have a 5-7min brew time.

Our Ninja coffee maker died on us 16 months into ownership. Unwilling to repeatedly buy garbage over the years, I checked out the recommendations and we gave it a go.

While we still need to get our fancy grinder, this machine makes coffee absolutely incredible. Added points because it's fun to watch and it looks good!

I can only speak for the basic Bunn coffee maker (I think This is the current version) but my parents, and both sets of grandparents own the basic Bunn coffee maker and have had them for as long as I can remember. IMHO I believe they make some of the best coffee at home, and their simple design prevents them from breaking down. I can only remember one issue my mom had, some part needed replacing, and she was able to get the part from Bunn in no time. (I am pretty positive they have a lifetime warranty, if not just great customer service). I have owned my own Bunn for about 4 years now and I have had no problems and love the coffee it makes.

Edit: Sorry if I offended any coffee aficionados! I am fully aware that this won't make an award winning cup of coffee. The bottom line of this post is in my personal experience, Bunn coffee makers last a very long time and make a good cup of coffee. My dad makes multiple pots of coffee a day, and they've had theirs for as long as I can remember. Anyways, Make sure to check the comments for other coffee maker ideas, seems there are several other recommendations being made!

Answer (1 of 2): I see only two cons. One is that by keeping the reservoir hot all the time they arenโ€™t very energy efficient although mine has a power switch that I turn off each morning and back on at night. The only other con is that it makes coffee too quickly.

r/Coffee on Reddit: Bunn vs Other Brands
October 6, 2020 -

Hi there,

I'm thinking about buying my mom a new coffee maker for Christmas, but I know absolutely nothing about coffee. She used to co-own a hole-in-the-wall cafe and used Bunn coffe makers. Since then, that has been her favorite brand. I think the main reason she likes them is because they keep a reservoir of hot water and evidently brew the coffee quickly. Does anyone have any thoughts about Bunn vs other brands? I'm not opposed to getting the Bunn, but if there is something better that she might not be aware of, that would be cool, too. She has a Keurig right now, but she doesn't love it.
