Why low acid

Smooth by design, measured by a lab

Coffee's acidity comes from many compounds. Chlorogenic acids (CGAs) are among the ones that shape the sharp, bitter edge in a cup, and roasting time and temperature decide how much of them is left.

  1. 1
    100% organic Arabica. Arabica beans naturally carry lower CGA levels than Robusta.
  2. 2
    Convection roasted. Hot air heats each bean evenly from skin to core.
  3. 3
    A slower, lower-temperature finish. It reduces CGAs further without over-darkening the beans.
  4. 4
    Independent testing. Third-party labs test for pH, chlorogenic acids, pesticides, mycotoxins and heavy metals.

How to brew

A full cup in one press

  1. Pop in a cup. Use any single-serve pod brewer.
  2. Pick your size. 6 to 8 oz for a bolder cup, 10 oz for a lighter one.
  3. Brew and enjoy. For iced coffee, brew the smallest size over ice.

FAQ

Questions about this coffee

How many single-serve cups come in a box?

Each box holds 12 single-serve cups. You can also buy a 3-pack of 36 cups or a 6-pack of 72 cups, which cost less per cup than single boxes. Every roast and flavor uses these same box sizes. Browse all of them in our single-serve pods collection.

Does Half Caff taste the same in bags, cups and steep bags?

Not quite. The Half Caff bags and single-serve cups are a medium roast, smooth and earthy, with notes of dark chocolate, plum and manzanita honey and a full body. The Half Caff steep bags have their own profile, softly sweet with caramel notes, so check that page if you prefer the tea bag style format.

What is Half Caff, and do I mix it myself?

Half Caff is a ready-to-brew blend of caffeinated and decaffeinated coffee, with less caffeine than our regular roasts. You do not mix anything at home; brew it the same way you brew any of our coffees. It comes in whole bean, fresh ground, 5 lb bags, single-serve cups and steep bags. See the Half Caff collection.

Will your single-serve cups work in my Keurig?

Yes. Our single-serve cups are made for Keurig-style brewers and work in most Keurig 2.0 models. If your machine only accepts its own brand's pods, check its manual or email hello@lowacidcoffee.com with your model before you order. Keurig is a trademark of its owner, and Alex's is not affiliated with Keurig. Shop single-serve cups

How much caffeine does the Half Caff have?

Half Caff blends caffeinated and decaffeinated coffee, so it has noticeably less caffeine than our regular roasts but is not caffeine free. Our steep bag guide puts a Half Caff steep bag at about 50 mg, roughly half a normal cup. With bags, the amount depends on how much coffee you brew, so we don't publish a per-scoop figure. Read the steep bag guide

What makes Alex's coffee low acid?

The beans and the roast. We start with organic Arabica, roast it with hot air convection and hold the final stage longer at a lower temperature. That slower finish reduces chlorogenic acids (CGAs), naturally occurring acids in coffee, without over-darkening the beans. An independent lab then measured pH and CGAs in our four core roasts. See the lab results

How much do I save with Subscribe & Save?

It depends on the product and pack size. A single 12 oz bag on subscription is 10% off its one-time price, and 3- and 6-bag subscriptions save more compared with buying single bags. Steep bag boxes are 20% off, 5 lb bags 15% off and variety packs 20% off their one-time prices. Single steep bags aren't available on subscription. The product page shows the exact price.

Description

If you love coffee but it doesn’t always love you back, Alex’s Low Acid Organic Coffee™ Half Caff Single Serve Cups make it easy to enjoy a smooth, flavorful cup with half the caffeine and none of the discomfort. They are perfect for anyone who wants the taste and aroma of real coffee with less caffeine and low acidity. Satisfaction guaranteed.

Alex’s Low Acid Half Caff offers about 50 milligrams of caffeine per serving, roughly half that of a standard cup, while keeping the same rich and balanced taste. This smooth and earthy blend delivers notes of dark chocolate, plum, and manzanita honey, creating a full bodied coffee that feels indulgent any time of day.

More than 30 percent of coffee drinkers experience heartburn, acid reflux, or stomach discomfort after drinking coffee. Many believe the issue comes from pH level, but that is not the full story. Coffee naturally contains many acids that contribute to flavor and aroma. The actual cause of upper GI distress is a compound called Chlorogenic Acid, especially CQA 3, 4, and 5. These compounds occur naturally in coffee and can rise significantly during drum roasting.

Most coffee roasters use drum roasters, where beans come into contact with hot metal. We take a better approach. Our patented convection roasting system uses a bed of hot air, so the beans never come into contact with steel. This method creates a precise, even roast and significantly reduces Chlorogenic Acid levels. The result is a smooth, rich coffee that is gentle on your stomach and easy to enjoy from the convenience of Single Serve Cups.

If you are skeptical, that is fair. There is plenty of conflicting information about coffee and acidity. Our process is supported by research from Dr. Taka Shibamoto, Distinguished Professor of Environmental Toxicology and Director of the UC Davis Coffee Center. His studies show that high levels of Chlorogenic Acid contribute to both bitterness and stomach irritation in coffee.

Certified Organic by Organic Certifiers. See for yourself why so many people call Alex’s Low Acid Organic Coffee™ the smoothest coffee they have ever tried. Order a box of Half Caff Single Serve Cups today and enjoy a cup that is smooth, balanced, and kind to your stomach.
