I have used Michael Zammataro's groundbait since 2015 when I first went to his factory in Essen with Einfachstippen. I have tried many of his groundbaits and use several of them all the time.
Brassen, Kanal-Mix Black, Rotauge, Turbo Cloud Natur & Black - Additive for Roach is Koriander.
The Turbo Cloud in Natur and Black is used in most of my mixes, and I usually add earth or the Kanal Mix. For Roach I add some Coriander additive and for Bream some Caramel additive.
I have used the Rotauge many times now - at the moment all the time - and it is a great groundbait on its own or mixed with others like the Roach and Skimmers Natur / Black. Great results with Rotauge!
I add VDE Black Earth to my mixes in the colder months.

I use Black Earth and Black Earth Heavy mostly in the winter months when you don't need as much food content in the groundbait, although the Black Earth is also good in the Summer.
Always pass the earth through a maggot riddle before using it.
I mix my Zammataro groundbait to the right consistency and the add the riddled earth as required. Then I mix them thoroughly together with a drill and whisk.
EXPO Expo is an excellent groundbait if you are after Tench and Skimmers - especially Tench.
