Make it what? You can do a flavor hop addition with 1oz of hops at 15 or 20 minutes with a little plain light DME. the add the Cooper's can at flame out. check out my recipes for ideas.
Brew it as 19 liters instead of 23. Use spray malt instead of sugar. Go up to a 11 gram pack of premium yeast. Just some ideas. Great beer can be made with Coopers.
