Sloe gin fizz: a sweet drink that is still a full drink of alcohol

A sloe gin fizz tastes like fruit and soda, and the alcohol is easy to miss. USDA portions one drink at 225 g carrying about 18.7 g of alcohol, 148.5 calories and 4.4 g of sugars. That figure is a recipe calculation, not a measured glass, and the sugar moves with the syrup and the brand of sloe gin. The NIAAA puts a US standard drink at about 14 g of pure alcohol, so one fizz holds more than that. We found no study of the cocktail itself, of sloe gin, or of the sloe berry in people. Everything below the composition comes from research on alcohol in general. The firmest of it is about food. In a crossover trial on 9 healthy men, drinking 0.30 g/kg of ethanol after a meal gave a peak blood alcohol of 13.3 to 17.7 mg/dl, against 30.8 mg/dl on an empty stomach, whatever the meal was made of.

As people eat it, per 3.5 oz (100 g)

How much is actually in it

• USDA lists a sloe gin fizz at 8.3 g of alcohol, 66 calories and 1.95 g of total sugars per 3.5 oz (100 g). — standard US recipe in the national food composition database Evidence E source
  8.3 g ethyl alcohol, 66 calories, 1.95 g total sugars per 3.5 oz (100 g)

What a real portion looks like

• One sloe gin fizz as USDA portions it weighs 7.9 oz (225 g) and carries about 18.7 g of alcohol, 148.5 calories and 4.4 g of sugars. — US dietary survey portion for one drink Evidence E source
  1 drink = 225 g: 18.7 g alcohol, 148.5 calories, 4.4 g total sugars
• In the United States one standard drink contains about 14 g of pure alcohol. — US adults, NIAAA definition Evidence E source
  1 standard drink = about 14 g pure alcohol

What your body absorbs

• Drinking 0.30 g/kg of ethanol after a meal gave peak blood alcohol of 13.3 to 17.7 mg/dl vs 30.8 mg/dl on an empty stomach in 9 men, whatever the meal's fat, carbohydrate or protein content. — 9 healthy men, ethanol 0.30 g/kg within 15 min of a standardized breakfast, crossover (n = 9) Evidence B source
  Peak BAC 13.3 to 17.7 mg/dl after meals vs 30.8 mg/dl fasting; AUC 1270 to 1767 vs 3210 mg/dl min
• Eating before a moderate alcohol dose cut peak breath alcohol from 0.064% on an empty stomach to 0.020% to 0.047% depending on the food. — 21 overnight-fasted healthy adults (10 male, 11 female), alcohol 0.3-0.35 g/kg, crossover (n = 21) Evidence B source
  Peak BAC 0.064% no food vs 0.047% snack mix, 0.031% bar, 0.020% full meal; 90-min bioavailability down 22% to 67.9%
• Vodka mixed with a sugar-sweetened cola gave a lower peak breath alcohol than the same vodka with a diet cola, 34.8 vs 38.3 ug/100 mL. — 12 healthy volunteers (8 male, 4 female) aged 19-64, vodka 0.5 g/kg with 'regular' or 'diet' coke, crossover (n = 12) Evidence B source
  Peak BrAC 38.3 (diet) vs 34.8 (regular) ug/100 mL; faster gastric half-emptying with diet mixer
• Speeding gastric emptying with erythromycin raised peak blood alcohol by a mean 40% after the same drink with a meal. — 8 male volunteers, ethanol 0.5 g/kg in orange juice with a beef meal, double-blind crossover (n = 8) Evidence B source
  Peak blood alcohol +40% (p < 0.01); larger total absorption
• A meal or a food bar eaten before vodka cut alcohol absorption by about 30% against drinking on an empty stomach. — 20 healthy participants, vodka 0.35 g/kg (men) or 0.30 g/kg (women), four-way crossover (n = 20) Evidence B source
  Relative bioavailability (AUC0-t) about 30% lower with the bar or control meal vs fasting

What it does to your health

• In a 28-day crossover trial, 30 g of alcohol a day as gin lacked the antioxidant changes seen with the same alcohol as red wine. — 40 healthy men, mean age 38, 30 g ethanol/day as gin or red wine for 28 days each (n = 40) Evidence B source
  Vs gin, wine lowered plasma oxidized LDL by 11.0 U/L (CI -17.3 to -6.1) and MDA by 11.9 nmol/L (CI -21.4 to -2.5)

Safety, limits and interactions

• Eight days of ranitidine raised the peak plasma alcohol after a small post-meal drink from 4.92 to 6.47 mg/dL. — 20 healthy men, ranitidine 300 mg or placebo daily for 8 days, alcohol 0.15 g/kg after an evening meal (n = 20) Evidence B source
  Peak plasma alcohol 6.47 vs 4.92 mg/dL (P = 0.05); 2-h AUC trend 3.89 vs 3.17 (P = 0.07)
• CDC states there is no known safe amount of alcohol use during pregnancy. — pregnant people and those who could become pregnant Evidence E source
  No safe threshold identified

What people believe that the data does not support

• Mixing vodka with carbonated rather than still water sped alcohol absorption on average, but 7 of 21 drinkers showed no change or a slower rate. — 21 fasted subjects (12 male, 9 female), vodka diluted to 18.75 vol% with still or carbonated water (n = 21) Evidence C source
  Mean absorption rate 4.39 vs 1.08 mg/100ml/min (p = 0.006); faster in 14/21

Who this works differently for

• The same 0.3 g/kg alcohol dose gave widely different blood alcohol curves between people and in the same person on different days, fed or fasted. — 24 healthy men, ethanol 0.3 g/kg before or after an evening meal on two days each (n = 24) Evidence B source
  Significant fed vs fasted differences in AUC, Cmax and time to peak; large inter- and intra-individual variability

The bottom line

Food before the drink keeps showing the same direction. In 21 fasted adults, in a trial sponsored around a food bar, a full meal cut peak breath alcohol from 0.064% to 0.020%, and in a second trial on 20 people a bar or a meal lowered absorption by about 30%. Food lowered the peak. It did not take the alcohol away. Both measured breath for 90 minutes after a vodka dose, not a cocktail. The sugar in the fizz may matter a little. In an open trial on 12 volunteers, vodka with regular cola gave a lower peak breath alcohol than with diet cola, 34.8 against 38.3 ug/100 mL, with wide spread between people. The idea that bubbles make you drunk faster holds only on average. In 21 fasted people, vodka with carbonated water was absorbed faster in 14, and 7 showed no change or a slower rate. That study did not randomize the order. The bigger lesson is how unpredictable alcohol is. In 24 healthy men the same 0.3 g/kg dose gave widely different blood alcohol curves between people and in the same man on different days. Gin is also no health drink. In 40 healthy men over 28 days, red wine lowered oxidized LDL by 11.0 U/L against the same 30 g of alcohol as gin, and these are blood markers, not heart events. Who should be careful. The CDC states there is no known safe amount of alcohol during pregnancy, and that covers a sweet cocktail as much as a shot. Stomach acid drugs can change the numbers too. In 20 healthy men, eight days of ranitidine raised the peak after a small post-meal drink from 4.92 to 6.47 mg/dL, a result right at the edge of significance with a dose far smaller than one fizz. Ranitidine itself is no longer sold in the United States. We have no card yet on drinking limits, on driving, or on alcohol and cancer, so this page does not cover them.
