Every once in a while I realise my education in practical Englishness is lacking. A PhD in English history only gets you so far and serious gaps remain that studying early modern pamphlets will never close. Among the things they won't prepare you for in university is sherbet. You may think this is not overly relevant, especially not in the context of German wine - and to be fair so did I (or would have, had I been aware of sherbet). Turns out sherbet actually matters, at least if you are English and for the first time in your life exposed to Nahe Riesling.

Meet the wine that tastes like sherbet.

A highly recommended, reasonably priced Riesling with Art Nouveau/Jugendstil label and named after the world's most famous intelligence agency - I pressed "add to shopping cart" before my brain had even processed this properly. You may not know this, but I am intrigued by the world of espionage, I like cheap puns and I have the marvellous ability to misread pretty much everything to make me giggle. So it took my brain another second after I had added the wine to my latest delivery to realise that (while the label really does feature angels with a Riesling gun!) there is no German humour reference to the CIA here.

Instead we are looking at the estate Riesling of one of the world's oldest wineries, and CAI stands for Carl August Immich. Please don't be disappointed, after all we are speaking about a man who blew up a mountain in order to make good Riesling.

Andreas Durst likes his photography natural, but stylish. And, not being one to be taken in by glossy surfaces and wines that wear a lot of make-up, as it were, Andreas Durst likes his own wines straight and clear. So when he makes a rosé, it's no surprise that it doesn't turn out all fruity and sweet.

By now word has got around that there is German red wine. I mean, it has, right? If it hasn't, can you please just nod politely and leave me the illusion that after shouting about it for a few years we have at least got that message out? So, as we all know by now that there is German red wine, let's deal with the fact that there is quite a lot of it these days. Germany, for instance, is the world's third largest producer of Pinot Noir - or Spätburgunder as it is known there and as you can see on the label below.

At the Langenwalter winery they don't just make some of this - almost half the grapes grown in the Pfalz vineyards are red, actually. This includes Portugieser, Dornfelder and Cabernet Sauvignin. So you'd think that with that much quantity around and a few hundred years of family history the Langenwalters will know something about making good red wine.

It has been a while since France, the world's greatest red wine country (yes, deal with it!) has drawn me into its sway. This time, it's the unlikely region of the Touraine. Lured by the relative exoticism of that appellation for red wine, by the very original varietal mix of Cabernet Franc, Pinot Noir and Malbec, and not least by my love for regional French reds of any ilk, it was more than easy to give in to temptation.

But don't get the idea that some highly strung luxury cuvée caught my eye with a suggestive wink. No, it was a working man's red, as befits the outcome of the recent presidential election.

Dutch wine - I bet you didn't see that one coming. To be fair, neither did we. And yet here it is, and it is not just any Nederlandse Wijn, it is a wine made from Riesling grapes grown near the Dutch city of Maastricht. The existence of Dutch Riesling is the latest and perhaps most groundbreaking in a range of shocking revelations uncovered by the Wine Rambler's uncompromising investigative journalism. Yes, ladies and gentlemen, it is true. There is world class German red wine. There is English still wine and it is even drinkable. And yes, there is Dutch wine too.

Is it drinkable though? The Wine Rambler dares another, potentially fatal self-experiment.

Pinot Blanc. Currently 50th grape variety in the order of acreage planted worldwide. Often seen as Chardonnays less expressive brother. And one of Germany's most reliably satisfying grapes. Most British wine lovers, and indeed most of them around the world, primarily associate this grape with Alsace, a connection that won't be easily challenged (we have tried before). To prove that Germany can indeed do outstanding Pinot Blanc could seem an uphill battle, therefore, but in fact it's the easiest task in the world, as we can let wonderful German Pinot Blancs prove it for us (and get to drink them into the bargain).

With the Harteneck winery of Baden's Markgräflerland subregion, this task is also in very steady hands:

"Oh my god, this looks so cheap." This is a common reaction I get when showing a "Bocksbeutel" bottle to British wine drinkers. What to me is the traditional bottle shape in the Franconian wine region of Germany reminds the UK of Mateus rosé, a mass produced, Portuguese wine brand invented in the 1940s. However, the Franconian bottles are much older than Mateus, in fact the bottle shape goes back to antiquity, and there is nothing unrespectable to it.

The same is true for the winery, although - like the bottle shape - it needs explaining. And don't worry, I won't forget about the wine either!

It's a sad thing indeed when a wine lover is failed by a wine, but can a wine also be failed by its tasters sometimes? We had such a case on our hands at a recent Wine Rambler full committee meeting: You judge for yourselves whether we are being too hard on ourselves. While the dry wines that go with dinners at Wine Rambler Munich HQ are usually settled on beforehand, the dessert offering is, for some reason, usually selected spontaneously during the course of the evening after lively, alcohol-fuelled debate. This has led to some very fortunate choices, inspired by the moment, but sometimes, some prior planning would have been preferable.

When the name Merkle came up on the most recent of these occasions, I thought of the 2009 Riesling-Gewürztraminer cuvée I had tasted at the winery last year. I remembered Gewürztraminer lushness, coupled with the Merkles' typical herbal spiciness, and I remembered above all sweetness. Just the thing, and a change from the more usual Mosel Spätlese or Auslese. I should have realised that the 2010 I had in my cellar was as different from the previous vintage as can be:
