OK so maybe I should clarify. There are a few high-ABV beers and beer styles out there. Typically, though, stouts are the easiest to do, because of their bold, strong flavours. High ABV fermenting is stressing on beers, and, similarly to wine, it needs aging to mellow out. But, for homebrewers, aging is not easy. Beer is a nutrient-rich environment, so bacterial growth is very easy. For wines, you can "stabilize" it, using sorbates and sulfites (even seen the "contains sulfites" label on wine or ciders?). Beers can be stabilized, but once stabilized, you can't bottle carbonate your beers, it needs to go into a keg. So it's a catch-22, a tossup and a balance. Easier solution? Brew a beer where the flavours of the beer hides some of the off flavours from the fermentation. Introducing the stout. Heavily roasted barley introduces flavours like espresso, dark chocolate, toasted nuts, bread crust and more. All strong, deep flavours, and they hide those flaws. Another style that hides it well is the IPA. Because it gets slammed with hops, and hops also hide those flavours.
That's why I can confidently say the majority of the beers will be in those two styles.
