Rio brazos

Poured this neat in a glencairn glass. This one is super odd to me. The nose is sweet and like an odd caramel flavor coming through. The palate has a mild burn, is peppery, and then the finish is where it throws me off. It taste like a "chemical" product or some type of caramel flavoring that tastes full of processed sugar. The finish has a lingering flavor after 2 minutes that flavor turns really sour. I wouldn’t recommend this at all.
