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

Ready for your brewer

  1. Measure. Start with 15g, about 2 tablespoons, per 8 fl oz of water.
  2. Brew. Drip, pour-over or French press. Use water just off the boil, about 195 to 205°F.
  3. Adjust. More coffee for a bolder cup, less for a lighter one.
  4. Store well. Reseal the bag and keep it cool and away from light.

FAQ

Questions about this coffee

How much coffee is in a 5 lb bag?

A 5 lb bag holds 80 oz of coffee, more than six and a half times a 12 oz bag. It suits households that brew every day, offices and anyone who shares their coffee. It comes in French Roast, Decaf, Rise & Shine and Half Caff, whole bean or fresh ground. Browse the 5 lb bags.

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.

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.

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

Can I return a 5 lb bag after opening it?

No. Opened 5 lb bags are excluded from returns. Unopened 5 lb bags follow our standard policy: within 30 days of receipt, with a return authorization from customer service before you ship it back. If a bag arrives damaged or incorrect, contact us within 7 days of delivery. New to a roast? Try a 12 oz bag first.

How should I store my coffee to keep it fresh?

Keep it tightly sealed in a cool, dry place, away from heat, sunlight and moisture. Our whole bean and ground coffee is sealed in airtight packaging to protect freshness, and each steep bag comes in its own foil packet, so open them one at a time. After opening, keep the package tightly closed between uses and follow the best-by date.

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 Fresh Ground lets you enjoy a smooth, rich cup with half the caffeine and none of the discomfort. It is perfect for anyone who wants full flavor with less caffeine. Satisfaction guaranteed.

Alex’s Low Acid Half Caff offers about 50 milligrams of caffeine per serving, roughly half the amount of a regular cup, while keeping the same bold, balanced taste. This blend is smooth and earthy, with notes of dark chocolate, plum, and manzanita honey. It’s ideal for a full-bodied, satisfying coffee any time of day.

More than 30 percent of coffee drinkers experience heartburn, reflux, or stomach discomfort after coffee. Many assume the problem is acidity, but that is not the full story. Coffee naturally contains many acids that contribute to flavor and aroma. The real irritant is a compound called Chlorogenic Acid, especially CQA 3, 4, and 5. These compounds occur naturally and can rise significantly during drum roasting.

Most coffee roasters use drum roasters, where beans come into contact with hot metal. We take a different approach. Our patented convection roasting system uses a stream of hot air, so the beans never touch steel. This process ensures an even roast and significantly reduces Chlorogenic Acid levels. The result is a clean, flavorful coffee that is easy to drink and gentle on your stomach.

If you are skeptical, that is understandable. There is a lot of confusing information about coffee and acidity. Our method 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. Try it for yourself and see why so many customers call Alex’s Low Acid Organic Coffee™ the smoothest and most enjoyable coffee they have ever had. Order a 5lb bag of Half Caff Fresh Ground today and enjoy coffee that tastes great and feels even better.
