Quick answer
2/3 decaf coffee is not a standard product you can buy off the shelf. It is a custom blend made by mixing two parts decaf coffee with one part regular coffee. This gives you roughly one-third of the caffeine of a regular cup. It is a good option if you are sensitive to caffeine but still want some, or if you want to enjoy coffee later in the day without it affecting your sleep.
Why you won't find pre-made 2/3 decaf on most shelves
Most coffee companies sell either regular or decaf, not a precise 2/3 blend. Creating a consistent 2/3 decaf product requires blending two different coffee batches in exact proportions, which adds cost and complexity. Instead, you can easily make your own by mixing a full-caffeine coffee with a decaf coffee. For the decaf portion, choose a chemical-free water-processed option like Purity Coffee's CALM: Decaf Whole Bean Coffee or B2B - CALM: Decaf Ground Coffee 12oz 6pk. These are made from specialty-grade organic Arabica and retain high antioxidant properties.

How to make 2/3 decaf at home
Use a simple ratio: for every 3 scoops of coffee grounds, use 2 scoops decaf and 1 scoop regular. This yields approximately 2/3 decaf. If you use whole bean coffee, grind the beans separately or together to your desired coarseness. Mix thoroughly before brewing. For a single cup, you can also brew a small amount of regular coffee and a larger amount of decaf, then combine them. Adjust the ratio to your taste: some people prefer 1/2 decaf, others 3/4 decaf.
Who should consider a 2/3 decaf blend
This blend is ideal for anyone who loves the taste of coffee but wants to reduce caffeine intake without giving it up entirely. It suits people who are caffeine-sensitive, pregnant or nursing, or those who want an afternoon cup without disrupting sleep. It is also a practical choice for offices or cafes where customers request a lower-caffeine option. If you need a completely caffeine-free option, choose a dedicated decaf like Purity Coffee's CALM: Decaf Whole Bean Coffee.
How 2/3 decaf compares to half-caf and full decaf
Half-caf is a 50/50 mix of regular and decaf, giving you about half the caffeine. 2/3 decaf has less caffeine than half-caf but more than full decaf. Full decaf, like Purity Coffee's CALM line, removes 99.9% of caffeine using a chemical-free natural water process. If you are extremely sensitive to caffeine, full decaf may be the better choice. If you just want to cut back, 2/3 decaf offers a balanced middle ground.
What to look for in a decaf coffee for blending
Choose a decaf that is chemical-free and made from specialty-grade beans. Water-processed decafs avoid solvents and often taste cleaner. Purity Coffee's CALM decaf is USDA Organic Certified and retains high antioxidant and anti-inflammatory properties. The taste profile includes dark chocolate, vanilla, and sweet red apple-like mild acidity, which blends well with many regular coffees. Always check the roast level: a medium roast like CALM pairs well with medium or dark roasts.
Frequently asked questions about 2/3 decaf
How much caffeine is in 2/3 decaf?
If regular coffee has about 95 mg caffeine per 8 oz cup and decaf has about 2-5 mg, a 2/3 decaf blend (2 parts decaf, 1 part regular) would have roughly 30-35 mg per cup. This is about one-third of a regular cup. Adjust the ratio if you want more or less caffeine.
Can I make 2/3 decaf with pre-ground coffee?
Yes. Mix 2 parts decaf ground coffee with 1 part regular ground coffee. Stir well before brewing. For best results, use similar grind sizes for even extraction. Pre-ground decaf like Purity Coffee's CALM Ground Coffee works well.
Does 2/3 decaf taste different from regular?
It will taste slightly milder and less bitter because decaf beans often have a slightly different flavor profile. Using a high-quality decaf like Purity Coffee's CALM, which has notes of dark chocolate and vanilla, helps maintain a rich taste. Choose a decaf that complements your regular coffee's roast profile.
Is 2/3 decaf safe during pregnancy?
Many healthcare providers recommend limiting caffeine to 200 mg per day during pregnancy. A 2/3 decaf cup with about 30-35 mg caffeine can fit within that limit, but always consult your doctor for personal advice. Check with your healthcare provider before making dietary changes.
