Realised the grind of coffee I was using with the electric burr grinder was too coarse for use with the new V60, I chucked some into the Porlex Mini hand burr grinder & reground it. I needed 15 grams & coincidentally, that's how much I had just ground.
A much better result, the brew didn't drain through the filter as quickly.
I went against my normal processes & had a cup with my dinner, thus far without ill effect.
Really impressed with the smoothness of the slow extraction vs faster methods such as the AeroPress.
