Since you racked off the gross lees already, I would add the oak cubes now. I take it Cabernet is on the right, and the lower level is the indicator that you lost more wine to the lees during that transfer?I racked both the Super Tuscan (ST) & Cabernet with Skins over to Big Mouth Bubblers last night at 1.014 and 1.010 SG. Having the wide mouths made moving the Skins in 2 muslin bags much easier. The plan is to leave the skins on for another 6 weeks for EM.
There’s more headspace than I would like, but when the bags of Skins rise, it will give then room for now. I did add the 1/4 tsp of K-Meta, just out of habit when racking, hope it doesn’t hurt The Cabernet had quite a bit more lees than the ST as you can see. I’m wondering if I should add the Oak cubes in now? or wait?? Thoughts ?View attachment 74753
Many of us will save and refrigerate the liquid part of the lees (whether gross or finer lees), after a day you can generally see liquid on top and solids on the bottom, and pour off the liquid to add back to your wine before discarding the solids. Basically you lose less wine in each racking if you take this step.
I'm also doing EM with my Super Tuscan but will just keep it in the same fermenter (30 L Speidel) as it is in now during primary. So I won't add oak cubes till I rack to secondary after EM is done. I think either way is fine, I'm just lazy and have no fear of leaving my wine on the gross lees for a few extra weeks.
