Order of ingredients by weight: Zucker, Guarana Extrakt (Träger: Maltodextrin, 2.5g Coffein/100g Brause), Citronensäure, Natriumbicarbonat, Maltodextrin, Aromen (Source: 1)

Assuming all caffeine is added specifically and not attributed to guarana (this is wrong):

Ingredient	Weight [g]	Calories [kcal]	Comment	Sources
Sugar	3	12	4 kcal/g	1,3
Guarana extract			0.621 kcal/g, 4-6% caffeine	1,5,6
- Maltodextrin	1.55	6	3.87 kcal/g	1,4
- Caffeine	0.125			1,2
Citric acid				1
Sodium bicarbonat				1
Aroma				1
unaccounted	0.325	0
Total	5	18		1,2

If all caffeine content is from guarana alone there's between 2.08 g and 3.125 g of guarana in the mix (100 / [4,6] % * 0.125 g) (source: 5). This would also add between 1.29 g and 1.94 g of starch ([2.08, 3.125] g * 0.621 gkcal/g) which would amount to between 4.54 to 6.81 kcal (source: 6).
