This has been a good measure for me. Sit at a distance and watch as those who drink spirits and those who do not normally drink spirits try what you've made. Don't dismiss this kind of feedback.
I wonder if similar articles were ever written about craft brewing or California wines. Not everybody is a fan I suppose, but he has some valid points. That the large batch blending is required speaks to the possible inconsistency of even the large distilleries and poor quality large volume produced spirits require more time and batch blending to become good. While really incredible spirit producers small, medium or large can certainly make great spirits regardless of there volume.
Just my 2 cents. Good to keep in mind as we crack into this world, don't cheapen your brand with something you don't love yourself.
