Loyalty runs on inheritance, not preference.
9 of 12 named a single 'go-to' brand and said they rarely buy anything else. The justification was almost never a taste attribute — it was a social inheritance ('since youth', 'my husband drinks it', 'our football crowd'). Asked to compare to the runner-up, most said the two tasted 'the same'.
3 of 12 broke the pattern. P25 chooses by region and ingredients; P20 buys by bottle design; P13 prefers alcohol-free and actively rotates based on price. Each of these three articulated a decision rule a waiter could repeat back.
Brand marketing that positions a beer on taste attributes is talking past the majority of buyers — they are not evaluating taste, they are honouring a habit. The entry point for a new brand is the social network, not the palate.
Push adoption through a single trusted person in a social circle (host, friend, regular bar). A direct-to-shelf launch without that social bridge will bounce off an 'inherited' loyalty it cannot touch. Sampling at football-watching parties beats Instagram reach for this segment.
