I have racked some Pinot noir into glass carboys and MLF continues. Had a mild sulphur issue (probably left on the gross lees a day or two too long), so dosed with Reduless, and will be racking after 72 hours according to recommended use. Q: There are oak cubes in the carboys, they have sunk into the lees. After racking can I just scrub them in a strainer, rinse with Star San, and throw back into the wine when it is returned to the cleaned carboys? My guess is no problem as long as sanitation is OK?
