depends on the quality you buy. i don't brew to save money, i do it to create variety for myself and to produce something of high quality, something the big breweries in germany don't give a shit about. simple mass produced beer is 11.49 eur for 24x 0.33 bottles (1.45 eur per liter) but you can even go cheaper than that if you can stomach it. mass produced beer tastes like shit in germany. beer from proper small scale breweries are around 5-8 eur per liter.
