The liquor, including limited-edition vodka, rum and whisky, is being sold by German company G-Spirits for around £100 each.
One of the main women involved in the project is Hungary's current Playmate of the Year Alexa Varga.
She is joined by Amina Malakona and Evelin Aubert, who have all been photographed topless demonstrating the process on the company's website.
The models will contribute towards producing 2,500 litres of each spirit in small batches and their photographs will appear on the bottles that go on sale.
G-Spirits have insisted that the campaign is in keeping with public health standards.
A spokesperson has said: "We pay high attention to a hygienic filling process. Furthermore medical personnel is present to check it."
