It is done.
Bottled 16 liters, blended with half a liter of very concentrated hibiscus tea (200g of dried flowers), juice of a freshly squeezed big (hand-sized) ginger root, zest of one orange, and sugar calculated to yield 2.45 volumes of CO2.
Light tartness from the hibiscus, as well as deep pink, light red color.
Refreshing but fiery ginger pairs well, ad gives it a lemonadey touch without becoming wimpy.
Looking forward to seeing how this will turn out.
