Topping off question

[Mazaruni]

My second batch of wine, VR Black Currant, is in its 3 gallon secondary, beginning to slow. When I transferred it, I had about 700 ml of extra which I saved for topping off after racking later on. The extra stuff has not completed fermentation yet, and I am keeping it in the fridge. Should I have put this in a smaller airlocked container to let it complete fermentation? How do you preserve extra so you don't restart fermentation later? Thanks!

I usually leave my smaller container on the counter under airlock right next to the carboy, especially while it's still fermenting

Agree, Use standard wine bottle, small stopper and a trap. Put it next to your "main batch".
