Frequently Asked Questions

Tonic wine is a fortified wine, meaning a spirit such as brandy or neutral grain spirit has been added to raise its strength. It is blended with herbs, roots and spices, and many tonic wines also contain caffeine. It tends to be sweet, with rich dark fruit flavours and a syrupy texture.

Tonic wine is generally between 15% and 20% ABV. That makes it stronger than standard table wine and comparable to port, sherry or vermouth.

Many tonic wines do. The caffeine comes either from natural ingredients such as kola nut or is added separately, and the amount varies by brand. Low-caffeine and caffeine-free versions are also available, so check the label.

No. Despite its Victorian marketing as a health restorative, tonic wine is not a medicine. It is an alcoholic drink with a high sugar content, and combining caffeine with alcohol can mask how drunk you feel. Treat it like any other alcoholic drink and follow NHS guidelines.

All three are fortified wines. Port and sherry are defined mainly by their grapes, production methods and regions in Portugal and Spain. Tonic wine is defined by its botanical infusion and caffeine content, and its identity is British and Caribbean rather than regional.

A red base wine is fortified with a neutral spirit, which raises the ABV and preserves it. Botanicals such as gentian root, angelica, quinine, cinnamon and clove are infused, caffeine is often added, and the wine is blended, sometimes matured, then filtered and bottled.

Traditionally neat or over ice in a rocks glass, sometimes with a wedge of lime. It also works in cocktails such as a punch, a spritz with soda water, a sour or a warm spiced toddy.

Not before opening. Its high alcohol and sugar content give it a long shelf life, so it does not need refrigeration until it has been opened.

In Jamaica it became linked with reggae, dancehall and sound system culture, and Caribbean migrants brought that tradition to post-war Britain. Separately, in Glasgow and the West of Scotland it developed its own identity within working-class communities.

Tonic wine dates back to the late 19th century, when fortified wines infused with quinine, iron and herbal extracts were sold as health restoratives. By the early 1900s commercial brands had added caffeine and proprietary herb blends.
