A daily, automated read of carbonated soft-drink shelf prices — quantifying the Sugar-Sweetened Drinks Tax spread on a like-for-like price-per-litre basis across the Coca-Cola portfolio.
Normalised price per litre of full-sugar Coca-Cola (subject to the levy) versus Zero Sugar (exempt), matched by format and pack count, flavoured variants excluded. A positive spread is the visible pass-through of Ireland's sugar tax onto full-sugar price-packs.
How unit economics change with pack size — the core of price-pack architecture. Larger packs drive down €/litre (the classic volume incentive).
