I’ve ordered a 1-pound bag of medium toasted French oak chips on Amazon and over the course of past two days added about 55g (~2oz) in each of the filled full carboys:

• B#1 Syrah “wild”
• B#2 Syrah “calm”
• B#3 Cabernet Sauvignon “good boy”

I again don’t have enough juice to top up the last outstanding carboy, it’s about ¾ full:

• B#4 Cabernet Sauvignon “bad boy”
