Whatever you brew will be wasted on him. Your friend doesn't really like beer. But he heard you're into homebrewing, and is trying to be a supportive friend. You'll no doubt brew up something on the mild, malty side, and he'll probably be able to drink it, but deep down, he'd rather be drinking a Miller. Of course, to be polite, he won't admit that, and will tell you how "drinkable" your beer is, but at the end of the day, he'd rather be drinking his Miller, and you'd rather not waste 6 hours of your weekend brewing a beer for someone who isn't as into it as you are.
Continue to offer him sips/glasses of whatever you brew, and he'll keep telling you it's "nice, but not for me," but don't waste a day on a batch neither you nor him will really enjoy. Just brew for yourself.
