Blackcurrant leaf tea comes from Ribes nigrum, the same shrub that produces the berries — a small perennial native to northern Europe and North America that can reach two metres. Here it's the leaves doing the work, and they give a cup that's herbaceous up front with a smooth, sweet finish: lemon and berry notes running alongside blackcurrant itself, honey, a touch of herbs, and something roasted underneath that edges toward coffee. Tea & Coffee packs it fresh to order at its Kent factory.
There's no caffeine in it, so it works as a late-day cup or a straightforward swap if you're cutting back on the stimulant without giving up something to steep. Leaves have long been drunk as a detox tea, and some traditional use extends the idea to metabolism and fat-burning, though none of that is settled science — treat it as folklore worth knowing rather than a guarantee.
To brew it, spoon the loose leaf into a filter or infuser, set it in the cup, and pour water straight off the boil. Give it a long steep, up to about seven and a half minutes, longer than you'd leave a black tea, to let the herbaceous character come through fully. Honey or lemon suit it well, though it holds up fine on its own too.
