I use Maris Otter or Pilsner as a base for everything. I also have a good selection of crystal, light wheat, victory, chocolate and dark munich.
For large quantities 2-row, maris otter, wheat malt and possibly pilsen.
Thanks for all your suggestions. Now I have to remember the hop ordering site I stumbled on here a while back, and read up on culturing yeast
A bag or more of 2-row, lots of wheat, Crystal 60, Munich, Pilsner, Chocolate, Black Patent and Biscuit.
