I believe I got some old amylase(no expiration date). My skittles wine wouldn't clear, even after superkleer. So I tried re dosing it with amylase and then a week later more superkleer. In the process I racked it into a large carboy so I could dose it together. When I racked it back to the original carboy and jug I had a pint of excess so I decided to drink it. My wife liked it and my daughter liked it but I didn't, so I put a little Green Hawaiian Punch in the bottle and an hour later it was clear. The 3 gal and 1 gal carboys were still very hazy. So I put 4 tbsp of Red Hawaiian Punch in the 1 gallon carboy. Now it is almost clear with a lot of sediment. The 3 gal carboy is still cloudy with no sediment so the punch is definitely clarifying the wine.
ETA:4oz of Hawaiian Punch is clearing the starch from 3 gallons, should be done in 24 hrs.
It's passing the laser test.
