Coopers mexican Cerveza how long in bottle?

Hi all - would this Cerveza be drinkable after say 3 or 4 weeks in the bottle? Im drinking my first batch which is a brewtec draught which started to taste good after 3 weeks, and i have 2 batches of lagers which i am leaving for 12 weeks. Just wanted to know from people who have made this one before what there experiances are. The instructions dont say to leave for 12 weeks like it does on the lagers. Cheers
