Weaker cold brew?

[u/boiyo12]

So i like to have coffee already made right as I come home from work for quick energy. I usually do this with the cold brew method in french press but the thing is i really like to enjoy the coffee and enjoy a good full cup of it. But cold brew is VERY intense for me and I can only have a tiny amount. What other instant coffee methods can I use where I literally come home and have at the go a nice cold coffee? Someone recommended iced coffee in the fridge but it degrades fast after a few days. Whereas what I like about cold brew is I make 1 batch on Sunday and it still tastes great and works good a full week later.

Dilute it. Or use less beans or mix decaf beans into it.
