Body and sweetness

Syrups for alcohol-free drinks

Simple, rich, honey, ginger and spiced syrups — how to make them, how long they keep, and which drinks each one suits.

Syrup is how you add sweetness without adding water, and in alcohol-free drinks it is also how you add body. Granulated sugar will not dissolve properly in a cold drink; it sits at the bottom and makes the last mouthful sweeter than the first.

Making syrup takes about four minutes and is the difference between a drink that tastes homemade and one that tastes assembled.

The four worth having

Everything below is made the same way: combine, warm gently until dissolved, cool, bottle, refrigerate. None of them needs boiling, and boiling actively harms the flavoured ones.

Simple syrup (1:1): Equal parts sugar and water. The neutral default. Keeps about a month refrigerated.
Rich syrup (2:1): Twice the sugar. Sweeter per millilitre and noticeably thicker, so it adds body without adding volume — useful when a drink tastes thin. Keeps longer, around six months.
Honey syrup (3:1 honey to warm water): Honey alone is too thick to mix cold. Brings a faint bitterness that is genuinely useful in alcohol-free drinks. Keeps around a month.
Ginger syrup: Fresh ginger steeped into simple syrup. The most useful flavoured syrup for alcohol-free drinking, because ginger supplies actual physical heat.

Spiced and infused syrups

Whole spices — cinnamon, clove, star anise, cardamom — steeped into warm simple syrup give you a mulled character on demand, which is far more practical than mulling a whole batch of drink. Steep for twenty minutes off the heat, then strain: leaving the spices in means the syrup keeps extracting and turns bitter and medicinal within days.

Herbs are the opposite: they want no heat at all beyond warm syrup, and only a few minutes. Boiled mint tastes of cooked spinach.

Storage, honestly

Sugar is a preservative, so a higher-sugar syrup keeps longer — that is the real practical argument for rich syrup over simple. Anything with fresh fruit, herbs or dairy in it keeps for days rather than weeks.

Label the bottle with the date. Syrup does not spoil dramatically; it goes cloudy or develops a faint ferment, and by the time you notice you have usually already made a drink with it.

The short version

Granulated sugar does not dissolve in cold drinks — syrup exists to solve that.
Rich (2:1) syrup adds body as well as sweetness and keeps far longer than simple syrup.
Steep whole spices for twenty minutes then strain; leaving them in turns the syrup bitter.
Herbs need warm syrup and minutes, never heat and never boiling.
