• Bags of EFFERBAKTOL 2 and 5 contain pre-adjusted SO2 quantities and are ready to use. • They are specifically suited for SO2 management in barrels, ageing containers or small tanks (variable capacity tanks). • They are equally recommended for the protection of musts in small containers. • Thanks to its composition and to its granule form, EFFERBAKTOL 2 and 5 avoids, in most cases, the tedious stage of a pump-over or mixing after sulfiting. • For sulfiting grapes, musts and wines in bigger containers (presses, harvest bins, large tanks, etc.) EFFERBAKTOL 50 or EFFERBAKTOL 100 should be used.
