We tapped our 3 trees last week and already have 50 gallons of sap!
Last year we tried this closed tubing system and it worked wonderful! There is very little room for contamination or spilling, and the buckets don't have to be emptied as often as other systems.
1/2" drill bit
clear plastic tubing 1/2" (We found this at Home Depot) You will need approximately 3 feet per tap.
5 gallon buckets, you can get food grade here: 5 Gallon Bucket
5 gallon bucket lids
Begin by washing your buckets and lids with soapy water.
Drill a hole in the lid of your buckets. You will need a drilled lid and a bucket per tap, then more buckets and lids to store extra sap.
Cut the tubing to length. You want a little wiggle room, but not so much excess that the tubing sags.
Now you wait for the bucket to fill. This year, it hasn't been long.
As the buckets fill, remove them from the tap, place a lid without a hole on the bucket for storage, and place a new, clean bucket under the tapped lid.
We also place stones on the empty new, empty buckets to give them some weight against the wind storms we've been having.
