When it comes to flavor and quality, there are definite ways to approach these concepts. First of all, good and bad are objective. Refrain from saying a beer is ‘good’ or bad’ per your own perspective. Someone less likely finds it suitable.
Good & Bad are absolutes. They put a line in the sand and yet they’re simultaneously squishy. Like what you like, find the good in all of it (even if you think it’s best for the compost pile), and move along.
Calling something bad is objective again. Could there be something truly wrong, amiss, awry, or off? Yes, and you can leave that to a qualified judge. I’d encourage you to continue to try everything. Seek out what suits you best, at the time.
Different is separate from good and bad. It’s like saying someone has a nice personality; it’s often a backhanded supposed complement to an ugly person (in the sayers definition anyway). Be nice, refrain, move on.
Quality is what things – beer and otherwise – should really be measured by. How do you gauge quality? In the beer world a big part is true to brand consistency, from sourcing to in the glass attention to best practices of creation and care. Go for quality. Quality isn’t always ‘expensive’ and it can include all sorts of $$ levels. A ‘cheep’ beer in a misnomer.
While you’re at it, get rid of light and dark when you talk about beer. Those terms are color terms – not flavor terms, where they are often misapplied. And they’re also relative to everybody’s own particular frame of reference.
Like what you like, taste everything, leave the judging on the back porch. Beer is meant to bring community together, to celebrate and get together. Unite over a beer. Leave the division for the mathematicians.
