Cement tanks with enamel coating were once very common, but went out of fashion in favour of steel and plastic composite tanks.
They're still widely found in traditional cellars in Beaujolais and Switzerland but until recently people did not put them in new cellars.
They are coming back in fashion for their thermal insulator effect, for "low intervention" winemaking.
I initially found Alpine Wines in a search for a good source of eisweins, which they certainly are. However, having bought a number of other wines from them as well, I have been truly delighted by the quality of the wine as well as their advice on the website and over the phone. Pretty much everything I have ordered has been a hit, and I'm rather picky. Excellent service and an excellent selection, most of which you will not find anywhere else. Truly unique. I will keep shopping here for the foreseeable future.
Delivery within 2 days, wines left where requested and one is able to order half a dozen wines at one time. We have always rated Swiss wines very highly and it is good to find a company that supplies such good quality wines.
As a half-Swiss I know what distinctive, quality wines Switzerland can produce. Until now, the problem has been locating them in the UK, since the demise of the Swiss Centre in Leicester Square many years ago. Keep them coming!
PS: I would like to see, and taste a pinot noir or two from the Germanic region - very distinctive from Burgundy, but more importantly from the lighter, thinner Germanic pinot.
