Advice on redistilling

[thomas puppish]

So, I ran a few older sugar washes through my 20 gallon still and wasn't happy with the product. The washes were not air locked when stored for several weeks, so I thought that may have lead to inconsistent, low proofs. Thoughts?

11 gallon wash got me about 2 gallons spirit. About 1/2 gallon was at a 80P - 130P range, the rest were heads and low wines.

I'm looking for a consistent, 140 - 160 proof shine. Should I dilute and redistill the low wines for a better product?
