As I understand briar is harvested, cut into blocks and boiled in water. If it is to be oil-cured, is this step inserted after the boiling in water or substituted for it? I've read that when oil-curing was begun by Dunhill they boiled the briar in olive oil. Has this been the oil of choice since then or are different oils used as selected by the briar cutter or the pipe maker? I've also read that oil-curing removes resins not otherwise released by water curing. True? It would appear to be that oil-curing is no better than prolonged air-curing and that oil-curing, although it imparts a nutty taste during break-in and has cachet from being begun by Dunhill, is an alternative, not better, cure.
