After Hours · The science
Evenings deserve their own coffee.
Your morning cup is about waking up. Your evening cup has a different job: the gym, the deadline, the drive home. After Hours pairs real Arabica with L-theanine, a combination researchers have studied for focus and alertness (the studies tested the ingredients, not our coffee). Ready in 4 minutes.

What's in your evening cup
-
Effect
In studies, caffeine + L-theanine together helped people stay alert and focused.
-
Caffeine
About 110 mg per sachet, roughly one regular cup of coffee. It is not decaf.
-
L-theanine
220 mg per sachet: a 1 : 2 ratio with the caffeine. It's an amino acid found naturally in tea leaves.
-
What's in it
100% Arabica coffee + L-theanine. Nothing else: no sugar, sweeteners, colours or flavourings.

Quick prep
Easy Pour: tear, hang on your cup, pour hot water. Ready in about 4 minutes. No machine, no shaker, no scoop.
The 1 : 2 ratio
Two of the best-known studies used 50 mg caffeine + 100 mg L-theanine. After Hours uses the same ratio: 110 mg + 220 mg per sachet. That's within the range researchers have tested (up to 150 mg + 250 mg).
Tea has only about 4–22 mg of L-theanine to 25–50 mg of caffeine. So the 1 : 2 ratio has to be added on purpose.
What the studies found
Each study compared the pair with a dummy drink that had nothing in it (a “placebo”).
Straight talk
The honest reading
- The effects are real but modest.
- Caffeine did most of the work; L-theanine added to it.
- The studies measured focus, attention and alertness, not workouts or sleep.
- They tested the ingredients, not our coffee.
Quick questions
Is it decaf?
No. About 110 mg caffeine per sachet, like one cup of coffee.
Is it a pre-workout?
No. It's coffee with L-theanine. No powders, sweeteners or colours.
When should I drink it?
Whenever your evening needs it: before the gym, the late meeting or the drive home.
Can I have it as my regular evening coffee?
Yes. It's 100% Arabica, so it tastes like real coffee.
What about sleep?
After Hours has about one cup of coffee's caffeine, the same as a regular evening cup. If you're sensitive to caffeine, start with half a sachet and see what suits you.
