The team at Six Barrel Soda have been working on a Tonic Syrup for ages. There are some good tonics out there and they wanted to make sure theirs was the best. They're funny like that. Six Barrel Tonic Syrup is zesty and citrusy with a gentle bitterness and it’s not overly sweet. It’s made with fair-trade organic cane sugar, lemon juice, lemongrass, lemon zest, a hint of pimento and contains quinine. Use it for house G&Ts or for dry, grown-up non-alc drinks. Garnish with lemon, thyme or cucumber. Each bottle will make 15-20 drinks, you’ll save on rubbish and also money. Plus your drinks will be better which is the main thing, and it's gluten-free.
