Germany’s Planned Sugar Tax Could Hit Plant Drinks, but Not Cow’s Milk

An oat drink without a single gram of added sugar could soon be taxed in Germany. Cow's milk, with its natural milk sugar, would stay tax-free. That is what the German Finance Ministry's outline paper for a planned sugar tax proposes, and it is exactly where the plan is now catching political headwind.

The sore spot: same sugar, unequal tax

The sugar in an unsweetened oat drink is not added; it forms during processing when the oat's starch is broken down. The sugar in cow's milk is not added either; lactose is naturally present. Two drinks, comparable sugar contents, neither with added sugar, but only one of them would be taxed under the outline. That imbalance is exactly what Zoe Mayer criticises:

“The culture war over plant-based alternatives appears to be continuing with the sugar tax.”

Dr. Zoe Mayer, nutrition policy spokesperson, Green parliamentary group (translated)

An unsweetened oat drink with the same natural sugar content as milk would become taxable under the outline, the MP notes, even though its sugar is process-related rather than added.

A pattern repeating itself

The unequal treatment is not new. Cow's milk enjoys Germany's reduced VAT rate of 7 percent, plant drinks pay the full 19 percent. REWE, vly, Berief and Oatly, among others, backed a petition to lower it; little has happened so far. In Mayer's view, the sugar tax continues the same pattern: products with comparable nutritional profiles are treated differently depending on whether they are animal or plant based.

“This continues the structural discrimination against plant-based alternatives that we already see with VAT.”

Dr. Zoe Mayer (translated)

Her demand to the Finance Ministry: target the tax specifically at added sugar rather than product categories. That would serve the health policy goal without making exactly those products more expensive that many people choose for climate or animal welfare reasons.

How binding is any of this?

Important context: the outline paper is based on recommendations of the government's finance and health commission and is still in the political process. There is no draft law yet, and the proposal is disputed within the federal government itself. Whether, when and in what form the tax arrives is open. Nothing changes at the checkout for now.

The debate joins a series of tax and labelling disputes around plant-based products, from the freshly reignited EU debate about banning the names veggie burger and sausage to the call for a reduced VAT rate on plant drinks.

The context: plant drinks are everyday products

What is being decided here is no niche: plant drinks generated 632 million euros in German retail in 2025, almost one litre in eleven of milk sold is now plant-based, and 78 percent of milk buyers purchase both. The full numbers and sources are in our World Plant Milk Day article, and our plant milk guide (in German) covers which drink works for what.

We will keep following the legislative process and report as soon as the outline becomes a bill.
