A recent survey by the There’s A Beer For That campaign has shown that 45% of consumers prefer to drink lager than any other drink, and that 60% had only ever tried up to five different styles of beer, despite the massive range that is currently available.
Some frustration was expressed at the reluctance of so many British drinkers to experiment, but this merely demonstrates a failure to recognise why many people drink as they do. For a lot of drinkers, the beer is merely an adjunct to a social event; it is not the purpose of it. If they've found a beer that suits them - whether it be a particular brand of lager, a national real ale brand such as Doom Bar, or a national smoothflow bitter - they feel no need to look any further. Furthermore, there are still people, a diminishing number admittedly, who feel brand loyalty: I've known people who have declared that Tetley Bitter was the finest pint on the planet. I've even known certain CAMRA members assert this, despite the beer's plummeting quality during the final years of the Leeds brewery.
I think it's unlikely that most drinkers of real ale, or of craft beer for that matter, want to spend every moment of their time in constant experimentation. If you're out for a night with friends and find a reasonable pint, you might decide to stick with that while you enjoy your evening, rather than experiencing a constant itch for something different.
There's no real need for impatience, considering that until the early 1990s, the choice of beer in most towns was severely limited to the products of the breweries who owned nearly all the pubs. We've come a long way since then, but there will always be drinkers who will stick to their favourite brand, or small range of brands. Changing people's drinking habits is a slow process, not unlike trying to do a U-turn in a cruise liner. The best approach is vive la différence - assuming we're still allowed to say that after the Leave vote.
