No, not sure when Paul's next grain bulk buy is, but he will/would need to be the one to contact whenever it does take place.
Also, Paul is/was starting a program where you keep your grain at his place (at least on paper) - and pick up as needed against your balance. Not sure of either details.
Looks like BBC TAproom might host a brew-in around mid- May. Might be able to get grain then.
