After the hole is formed, a "spile" or "spout" is added. Many Types of spiles are available, if buckets are to be used for collection. In years past, hollowed elderberry stems were favored for tapping; however, these spiles will not usually fit tightly in the tap, may damage the tree or can even be a source of infection. Commercially available spiles are a much better alternative. These spiles should be cleaned in a 1 to 20 bleach to water solution and rinsed several times. Cleanliness is very important to tree health and sap quality. When deciding on spile type, the decision on what type of bucket to use is also important. Spiles are usually made to service a particular type of bucket. If everyday plastic buckets are used (such as used food-grade buckets often available for free at bakeries or restaurants), spiles with hooks may be a good alternative. If commercial buckets are used, spiles should be suited to the bucket. Spile should be tapped into the tap hole gently enought to avoid tree damage (putting a split in the trunk), but firmly enough to seat the spile. Remember that the spile will have to hold the weight of up to 2 gallons of sap in a good run. Check the tap and then attach the buckets to the tap or the tree.
