Ginger Beer
A carbonated ginger drink with real heat to it, brewed traditionally rather than simply flavoured. The name misleads twice over: most bottles on a shelf are soft drinks under 0.5% alcohol, and most are flavoured and carbonated rather than brewed at all.
Quick Facts
Flavour Profile
Primary Flavours
Tasting Notes
Hot and spicy with a deep ginger burn, balanced by sweetness and a little citrus; noticeably fierier than ginger ale.
Storage & Handling
Refrigerate and use within a day or two of opening; cloudy sediment is normal in brewed styles.
Shelf Life
Unopened: 6–9 months. Opened: use within a day or two; sediment is normal.
Usage
Built over ice in spicy highballs, 100ml to 150ml topping a spirit and lime. The Moscow Mule and the Dark ’n’ Stormy both depend on it, because the heat is what stands up to vodka or rum where a sweeter mixer would simply disappear.
Brewed, Not Flavoured
Ginger beer began as a genuinely fermented drink, and the culture behind it is a curiosity in its own right. The ginger beer plant is not a plant at all but a symbiotic mass of a bacterium and a yeast, kept and fed in the way a sourdough starter is. Fermentation produced the carbonation, a little acidity and a trace of alcohol. Almost nothing on a supermarket shelf works that way now. Most bottles are ginger flavouring, sugar and forced carbonation, which is why the heat varies so wildly between brands and why several of them taste of little beyond sweetness.
Against Ginger Ale
Ginger ale and ginger beer are not two strengths of the same drink. Ale is clear, light and built around the flavour of ginger, while beer is cloudy, heavier and built around its burn. Swapping one for the other does not weaken a Moscow Mule so much as change what it is, leaving something that reads as sweet and faintly spiced rather than hot. The pungency comes from gingerol in the fresh root, which converts to shogaol when the ginger is dried and turns sharper still. A bottle listing ginger extract well down the ingredients is unlikely to hold much of either.
The Mule and the Copper Mug
The Moscow Mule was assembled in Los Angeles in 1941 by John Martin, who was trying to sell Smirnoff vodka, and Jack Morgan, who had ginger beer he could not shift. The copper mug arrived with it and has long outlived the marketing. It is worth being straight about what the mug does. Copper conducts heat readily, so it takes the drink’s temperature quickly and feels cold against the lip, but it does not insulate and will not keep a drink cold for longer than glass would. Unlined copper also reacts with acidic drinks, which is why food safety guidance favours a lined mug.
Buying It
Heat is the thing to buy for, and it is not something a label reliably tells you. Read the ingredients for ginger appearing early rather than as an extract at the end, and treat cloudiness as a hint that the root is present in quantity rather than as a flavouring. Sugar levels vary enough to matter in a drink that is mostly mixer. Once opened it goes flat within a day or two whatever the bottle claims, so a small bottle used at once beats a large one kept in the door of the fridge.
Pro Tip
A weak Mule is almost always weak ginger beer: pick one with real heat before you blame the vodka.
Top Tips
- Buy for heat rather than for the word on the label. Ginger appearing early in the ingredients is the useful signal.
- A copper mug takes the drink’s cold quickly and feels it against the lip, but it does not keep the drink cold. Use a lined one.
- Open a small bottle. Ginger beer goes flat within a day or two, and a flat Mule is a lost drink.
Possible Substitutions
- Ginger ale (milder and sweeter)
- Ginger syrup topped with soda water
Production Method
Ginger beer was traditionally brewed by fermenting ginger, sugar and water with a starter culture, the 'ginger beer plant', producing a cloudy, lightly alcoholic drink. Most modern versions carbonate a sweetened ginger brew or infusion to a non-alcoholic strength while keeping the cloudiness and heat. Fresh or dried ginger, sometimes with chilli or citrus, sets the level of spice.
History & Context
Brewed ginger beer was a fermented, mildly alcoholic drink in 18th-century England before becoming the soft, carbonated version we know. It gives the Mule and the Dark 'n' Stormy their bite.
Common Questions
Is ginger beer alcoholic?
Almost never, as sold. Traditional brewing produced a trace of alcohol, but the bottles sold as soft drinks sit under 0.5% and are treated as non-alcoholic. Separately branded alcoholic ginger beers do exist, are labelled as such, and usually sit around 4%.
Ginger beer or ginger ale?
Beer for anything meant to bite. Ale is clear and light and carries the flavour of ginger without the burn, so a Mule made with it comes out sweet and mild rather than hot. They are different drinks rather than two strengths of one.
Why is my Moscow Mule weak?
Usually the ginger beer rather than the vodka. A mild or heavily sweetened bottle gives the vodka and lime nothing to push against, and the drink reads as flat. Too much ice melt finishes the job, so build over plenty of ice rather than a little.
Why a copper mug?
Because it came with the drink in 1941 and stayed. Copper conducts heat quickly, so the mug reaches the drink’s temperature and feels sharply cold to the lip. It does not keep the drink colder for longer, and unlined copper reacts with acid, so use a lined one.
