Do a good long pour of boiling water in the v60. Make sure it's hot to the touch. This won't eliminate temp drop but at least help.
Another question: is it a glass v60 or plastic? The plastic ones work much better at keeping the temp counterintuitively.
It's actually metal. I figured the metal shouldn't sap much energy from the water since it doesn't have much thermal mass
Plastic tends to be the best, imo. I don't even really worry to heavily about preheating when using my plastic v60. But if j. Brewing with my Stagg XF, I absolutely place the Stagg XF on top of my Stagg kettle as well while it gets up to temp. Though the Stagg XF does have the benefit of being double walled stainless steel, so it does a great job of keeping temp.
I'd honestly love to see someone measure temp drop of metal vs plastic V60s. Although metal conducts heat more easily (i.e. it "takes" heat from the water more easily), it's thermal capacity is lower than plastic, glass, and ceramic. In my mind, preheating the metal should be less of a concern because it takes less energy to bring the metal up to temp. This is all theoretical though. Maybe I'll meet someone with a plastic V60 one day and ask to borrow it for this exact test.
