How to use a Refractometer & caveats with it

[Single Malt Yinzer]

I prefer using a refractometer over hydrometers. For me it came down to this: I make a HUGE mess every time I use a hydrometer with wort. Even so I wanted to know which is more accurate, etc. So I'm sharing this info for others to learn about them. In short - just buy one. Cheap ones are $35 or so and do good job. The caveat for using them is that the once the fermentation begins the SG reading will be off. No problem, there are several online calculators available to correct it for you.
