Porous Pegs – Real Ales
- Twin (or double) porous pegs are used in such a way that they eliminate the need for separate soft and hard pegs. Made of oak sap wood, they are in effect two pegs left attached to one another during manufacture, the result being a double length peg, which can be broken down into two pegs of standard length when required.
- The twin peg is inserted into the spile hole, and the harder it is driven in, the more restriction there is to venting, thus giving the required control. Vigorous working of the beer may cause the upper peg to become blocked, in which case that can be broken off to leave the lower peg still in the spile hole to continue venting, or subsequently to be knocked in more tightly to “hard” peg the cask.
