I've only made two toucan original series lagers and a toucan stout. The lager turned out very nice - similar to a pom superlager but without as much alcohol of course. I would imagine the Pale Ale would be hoppier than the lager. I find the Real Ale as a one-can to be plenty bitter and wonder if the Pale Ale is as hoppy?
It that's the case I would maybe chuck in 750g of LDME or a can of light liquid ME to balance the bitterness. With the stout I used two cans plus a kilo of LDME plus 750 dex and it's dynamite but the extra fermentables balanced out the bitterness nicely.
Only one bottle left
Also suggest a cleaner yeast like Nottingham as the Coopers kit yeast may turn out too fruity.
