However, not all new developments are ephemeral. Undoubted fads, like that strange urge bartenders had to make blue drinks a while back, will always come and go - but every so often you get a drinks evolution that makes you sit up and take notice.
The most recent of these for me has been the increase in the number of smoked beers. I don't just mean beers that have been infused with wood smoke, but also beers that have been given a smoky touch on the palate by the use of wood in the ageing process.
Smoked beer has been around for a long time in the form of German rauchbiers, which were made with malt dried over an open flame, imparting a smoky character.
Over here there have been quite a few examples down the years as well, but there currently seems to be a tremendous amount of choice when it comes to smoky beers. Plenty of breweries are making them and they are really worth trying.
I'm loving The Big Smoke from 8 Wired, a heady blend of rich wood smoke and chocolate and coffee flavours, but there are plenty of others I would happily recommend. Stoke's Smoky Ale (part of the Bomber range) is reliably good and readily available, as is Invercargill's Smokin' Bishop. Deep Creek's Scotch Ale gets a smoky touch from the use of whisky barrels in the ageing process, giving a lovely warmth on the back of the palate.
The Sprig and Fern brewery released a beautiful barrel-aged beer recently, and keep an eye out for a special new beer from them, presently going by the name Pearl Project. I tried some from the tank recently and it just about knocked me on by backside, so good was it. It's well worth getting a few riggers of when it comes out.
There are some more, well, polarising beers out there as well. If you love the big, peat-smoke flavours of Ardbeg whisky, you'll love Yeastie Boys' Rex Attitude. This award-winning golden ale is made with heavily peated malt to give a real whisky hit. I've tried it and it reminded me of drinking a glass of Lagavulin single malt submerged in a pint of barley wine.
It's a once-in-a-lifetime experience for those who love their flavours big and bold, but be warned - a little goes a long way.
