I think to get good information you need multiple sources. It helps control differing opinions and agendas and gives you a more well-rounded perspective. Luckily, we have a lot of great sources in the whiskey world. K & L, Cowdery Blog and Newsletter, WA blog and mag, Sku, Sour Mash Manifesto, SB, etc. That's a lot of high quality writing and information, and most of it is free.
The K&L blog is great; and I don't use that term lightly. I don't know of any merchant blog in any field that is even close to that good.
