Stewills,
I recommend adding a kilo of liquid malt extract in place of the usual kilo of dextrose or sugar, and about 20g of saaz hop pellets to that Morgan's pilsener. I also recommend getting 200g of carapils grains (get your HBS guy to crack them for you) and soak them in 2-3L of just boiled water for about 20 minutes. Strain the water from the grains through a fine seive, or grain bag into a large pot, add your kilo of liquid malt, dissolve and boil for 15 minutes. When you turn off the heat, throw in the saaz hops then gently tip all this into your fermenter. Add the kit, dissolve, then top up with cold water before you pitch the yeast. This takes only another half hour, but will drastically improve the flavour, body and head retention of the standard Morgans kit. I made the Morgans Pils as my first kit beer, with just a kilo of dextrose and although it tasted kind of like beer, it really wasn't something I was happy to share with people. It had no head retention either.
Welcome to an addictive but rewarding hobby!
