Tea Boosters

No. Samurai Shot in a 500 ml bottle is a concentrate for multiple servings. The manufacturer describes serving a small 50 ml shot, or mixing a measured amount with water or another liquid. Check the quantity and serving instructions on your flavour’s label. Samurai Energy in a 330 ml can and the sparkling Royal Moments and Geisha Velvet drinks, by contrast, are ready to drink without dilution.

Calculate caffeine for the amount you will actually drink. According to the manufacturer, Bitter Green contains approximately 65 mg per 50 ml. Adding water does not change that caffeine dose; it only increases the volume of the drink. Samurai Energy Pu-Erh & Blueberry lists approximately 40 mg per 100 ml, or 132 mg in a full 330 ml can. Check the units before comparing different products.

The manufacturer lists Gingerhead as caffeine-free; its base is ginger, turmeric, lemon and chilli. It is not sugar-free, however, and it has a pronounced spicy taste. Expect caffeine in the tea-based options and read the warnings on the label. Do not choose a drink for a child just because it has a fruit flavour or says “natural”; the caffeinated options are not intended for children.

No. Bitter Green and Pure Dark have recipes with no added sugar, but Sweet Flower and Gingerhead contain cane sugar. Matcha Booster contains pear concentrate, and Samurai Energy Pu-Erh & Blueberry uses a stevia-derived sweetener. Choose by the ingredients of the particular product. Adding juice or syrup to the finished drink also changes its sugar and energy content.

Reseal the opened concentrate, keep it in the fridge and use it within the period stated on its label. One storage period does not automatically apply to shots, sparkling drinks and cans alike. Tea concentrate may have natural sediment; this alone does not necessarily indicate a fault, but it is not proof of freshness either. Note the opening date if you use the bottle gradually.
