I am new to homebrewing. Just did my second batch. The first one was an extract kit for an IPA. The second was an extract kit for an Oktoberfest. I used ale yeast on both. They taste very malty. Almost similar. There is an obvious change of taste as the IPA was maltier. But... The 2nd batch (Oktoberfest) tastes almost the same. Any suggestions what could be happening???
