I went to several Coles and Woolworths checking manufacturing dates. Most are Sept/Oct 2018 and a few from Jan 2019. From this I can make an assumption that original estimated quantity for 3 month period has been exceeded due to increased sales leaving a shortage. Blend and pack would have set slots to make batches of BAL in between other orders. This could account for the shortage. If this is the case it means demand is very strong.
