These five boxes share a 20-bag format and current price, which makes flavour and caffeine (not packaging) the useful decision.
The simplest tasting ladder
Brew Pure Green first. Then try Jasmine, Lemon and Mint one at a time, keeping water and steep consistent. This shows if you enjoy green tea itself or mainly the added aroma. Put Decaf beside Pure Green last, because decaffeination is a processing difference rather than a flavour garnish.
Floral, citrus or cooling
Jasmine is perfume-like and aromatic; lemon brings brightness and familiarity; mint provides a cooler finish. None is objectively more refined. A flavour that masks bitterness can be helpful to a new green-tea drinker, while an experienced drinker may prefer the plain baseline.
Caffeine and the word decaf
Standard green tea naturally contains caffeine. Decaffeinated green tea has had most caffeine removed, but “decaf” is not automatically “caffeine-free.” People who need strict avoidance should follow the current manufacturer statement and medical advice rather than a category assumption.
Brewing without bitterness
Freshly boiled water can make some green teas harsher. Follow the pack temperature, or let the kettle cool briefly before pouring, and avoid extending the steep simply to chase darker colour. Change one variable at a time; cooler water and a shorter brew often reveal more sweetness.

How we keep this guide useful
teas.co.uk both stocks these Twinings greens and writes this guide. No brand paid for inclusion or position. Our starting list is every Twinings green currently stocked here, grouped by caffeine, format, ingredients, tea family and intended use. "Best" here means the most suitable Twinings green for a given need, judged on this dated list rather than any universal tasting.
Box names like Sleep, Digest or Defence are treated as range labels here, not as medical evidence. Check the current Twinings box for its ingredient list, allergens and brewing steps. If you are pregnant, on medicines or managing a long term condition, run ingredients like liquorice root past a suitable clinician. Last editorial and catalogue check for these Twinings greens: 8 August 2026.
