I definitely agree about reading up on brewing, you won't be disappointed! Brewing is very fun, and satisfying. To give a very broad answer to your question, the process of making wort involves steeping malted grains in water and holding at a specific temperature(s) to allow certain enzymes to convert the grain starches into fermentable sugars, after enzyme activity is finished the brewer boils and makes additions of hops. The liquid that is now ready to ferment is your wort (btw, it's very delicious even before you ferment and turn it into beer)
