Once you get access to the Bazaar Sidestreets there is a one off decision A Rainbow of Offerings which will give you varous items depending on your choice.
Just looked at the choices being a Fearsome Duellist gives 4 cellars of wine. I chose the Master Thief option when I played it though.
Five Cellars of Wine in my inventory (four from Rainbow of Offerings plus one bought at Bazaar Sidestreets). I just need to wait for the Opportunity Card :) Thanks everyone for all the wonderful and useful advice.
