Yes, decaf can be delicious

Recently switched to decaf for health reasons. This is the best decaf I found by far. We use a drip brewer into a carafe, and I’m able to have a pot available throughout the day. We also love supporting a local business!!!

Rich and bold

I love strong coffee and this one is so far my favorite. It has a rich, smooth flavor and does not bother my stomach or throat. I just reordered more since I enjoyed it so much.

I love all of General Warfields special specialty coffees. I like Peru I like Uganda and Ethiopia and I don’t know which one is best but I think of the three they’re all good but I think my favorite is Peru.

For a decafe it had some flavor and if i maded it stronger it was still good and not funny tasting.
Just ordered two more flavors and if they are good i will be a happy camper.

Easy transition from caffein

“You should cut out caffeine “ words that made me panic .. I have loved coffee since I was very young and woke up to the robust fragrance of strong coffee. My Dad would put a few spoonfuls in my milk to get me to like milk…. I never could drink it! But coffee I drink every day. I liked it strong with no sugar and just a little white. You know it is good coffee when you pour a little white and it mushrooms up from the bottom to the top. So of course I tried it with my very first cup of General W. And what a beautiful explosion it was … I know I have
Made the right choice because previous brands I tried not so much. Now I have a cup in the afternoon because I can🎶

Great Low Acid Coffee, Highly Recommended

My wife Brenda loves coffee however, the acid in coffee can really upset her stomach. General Warfields Special Blend Whole Bean Coffee does not create any issues that other strong coffees do. It has a deep and rich flavor that does not over power the pleasure of drinking coffee. If you are looking for a great cup of coffee without the acid this is the coffee for you.

Great tasting coffee!

I bought 2 different brands of low acid coffee. Warfield’s coffee trumps the other brand by a mile! Delish!

Peruvian Perfection

Talk about a perfectly balanced roast. The Peruvian and Ugandan are my favorites...can't go wrong with either.

My favorite selection!

Having tried them all, this one is my favorite. It’s slightly milder/sweeter than Uganda or original, but doesn’t lack in flavor! Very pleased with all my purchases.

Medium bold flavor

A solid but slightly stronger brew. A f you like a pop in your coffee, you won’t be disappointed!

I thought Nespresso coffee was good, but this is next level. I am so glad I started drinking whole bean organic coffee.
