3rd Jar cloudy...then clear

[Grappa-Gringo]

Good day everyone... here's a quirky one. We were distilling yesterday, as I've done many times before, -- 10 gal pot over propane, 2 inch piping, -- liquid was a mix of corn and rye that was fermented and filtered so there wasn't any chance of scorching or such.... We were running it hard and fast for a good strip. We had to go through roughly 15 gallons -- basically 2 runs of 8 gallons each. We ran first batch, with nice and clear drip for almost 3 liters. Then came a cloudy drip for a just shy of a liter.... then back to clear. Percentage was still pretty good on the cloudy bit....
I know we were running into the tails, but it was strange that it went back to clear after a cloudy bit.... This has happened to me previously, but I've never really thought about it till yesterday. Insight please.
