Ginger Syrup

One US cup of ginger syrup weighs between 293.5 and 308 grams, depending on how the cup is filled and which source measured it. That range is the answer; a single number would not be. Every figure behind it is below, with the method each source used.

Also called ginger cocktail syrup, ginger simple syrup, fiery ginger syrup, spicy ginger syrup, cocktail ginger syrup.

TL;DR: **One US cup of ginger syrup weighs 280 to 310 g depending on brand and product family.** Two distinct product families exist under the same name: real-ginger artisan (Liber & Co Fiery Ginger, Morris Kitchen, Portland Syrups, Liquid Alchemist) and commercial ginger-flavor (Torani, Monin, Fee Brothers). Real-ginger artisan runs lighter (280-298 g/cup) due to ginger juice water content displacing sucrose; commercial ginger-flavor runs heavier (300-310 g/cup) because it is essentially rich sugar-water syrup with flavoring. King Arthur does not publish ginger syrup.

Ginger syrup as a discrete cocktail ingredient is a relatively modern American bar product, dating to the craft-cocktail revival of the mid-2000s. Its cultural ancestor is Jamaican ginger beer plant fermentation — a symbiotic culture of yeast and bacteria that produces naturally carbonated ginger beer over several days — and the pre-Prohibition-era ginger-based punches and cordials that faded from American drinking culture through the twentieth century. The modern rebirth traces to two cocktails: the Moscow Mule (vodka, ginger beer, lime, dating to 1941 but popularized by copper mug fetishism in the 2000s) and the Dark 'N Stormy (Gosling's Black Seal rum, ginger beer, lime, a Bermudian trademark since the 1980s). Bartenders wanting more control over ginger intensity and sweetness began substituting ginger syrup for pre-made ginger beer, and craft brands like Morris Kitchen (Brooklyn, 2009) and Liber & Co (Austin, 2013) built entire product lines around fresh-juiced ginger as the differentiator.

The two-product-family split defines the modern market. **Real-ginger artisan syrup** starts with fresh ginger root that is either cold-pressed for juice or blended and strained to extract maximum flavor compounds (gingerol, shogaol, and volatile terpenes). Liber & Co's Fiery Ginger Syrup uses 50% organic Peruvian ginger juice by volume plus pure cane sugar; Morris Kitchen combines cold-pressed ginger juice with cane sugar and invert cane sugar to prevent recrystallization and produce a silky texture; Portland Syrups and Liquid Alchemist follow similar real-ginger formulations. **Commercial ginger-flavor syrup** (Torani, Monin, Fee Brothers, Finest Call) is fundamentally a cane sugar-water base with natural or artificial ginger flavoring and preservatives — no real ginger juice at all. The flavor is thinner and one-dimensional, closer to ginger candy than to fresh ginger, but the price is a fraction of the artisan cost and shelf life is longer.

The density difference between the two families is real but modest. Real-ginger artisan syrups converge around 50-55° Brix based on published sugar content per serving (Liber's label shows 10 g sugar per 15 mL serving, implying 667 mg/mL sugar concentration and roughly 291-298 g per US cup). Commercial ginger-flavor syrups run richer at 60-65° Brix because they follow the standard commercial flavored-syrup profile, landing at approximately 300-310 g per US cup. Sucrose-water density tables at 20°C give the physics: 50% w/w sucrose = 1.230 g/mL (291 g/cup), 55% w/w = 1.259 g/mL (298 g/cup), 60% w/w = 1.289 g/mL (305 g/cup), 65% w/w = 1.319 g/mL (312 g/cup). Real-ginger variants may skew a few grams per cup lighter than pure sucrose at the same Brix due to the water and suspended fibre content in fresh ginger juice; commercial variants track the sucrose-water physics directly.

In the ExactCups syrup cluster, ginger syrup joins the **cocktail-syrup family** alongside grenadine (280-320 g/cup) and orgeat (288-320 g/cup). All three follow the same real-fruit vs commercial family split, and all three cluster in the 280-320 g/cup band — well below the 336 g/cup cluster (honey, agave, barley malt, golden syrup at 76-80% solids) and below the 320 g/cup cluster (date syrup, pomegranate molasses, cane syrup, sorghum syrup at 65-70% solids). The pattern is consistent: cocktail syrups optimize for pourability and flavor integration in mixed drinks, not for maximum sugar concentration, so they run at 50-65% Brix rather than the 65-80% Brix of concentrated baking syrups.

Practical bartender recommendation: for a proper Moscow Mule, Dark 'N Stormy, Penicillin, or any cocktail where ginger drives the flavour, use a real-ginger artisan brand (Liber & Co, Morris Kitchen, Portland Syrups) — the fresh gingerol content translates directly to the finished drink's aromatic complexity. Commercial ginger-flavor syrups work for volume applications where cost matters more than character. Weigh at approximately 295 g per cup as a central working figure across both families. Store refrigerated after opening; artisan real-ginger syrups typically keep 4-6 months refrigerated, commercial preservative-containing syrups keep 12+ months.
