The time for using Cu++ is at the end of fermentation after the first rack. Ferment. Rack + 30ppm SO2. 2 weeks, rack again add Cu++ (copper sulfate at 0.2ppm white or up to 0.4ppm red). rack again in 2 weeks no SO2 then. rack again in 3-4 weeks, add SO2 again.
Months later is not the time to add copper sulfate. By then the Hydrogen Suflide has become bound and copper will do little to no good.
We use Stavin oak bean all the time with our used barrels and in tanks. HOWEVER, we also micro oxygenate the wine at the time of oak in tanks. We use 2 to 4 g/l oak beans. at 2 g/l that figures out to 0.336 oz. of oak beans for every 1 gallon.
