DipWSET Theory: Tasting German Riesling

I don’t know why, but I found that, during my WSET Level 3 studies, starting with Germany was really helpful. Maybe because the regions are completely foreign to me; the wines not regularly available in my area. Perhaps, embarking on a whole new adventure was the way to jump in. And, now, studying for my Diploma, I find the country calling to me again.

When I first started posting about my studies, I began with an exploration of major German regions via the country’s most popular grape. The kind of “dry” tasting notes, if you will, gave me a good idea of what kind of climate and terroir each individual region has. (See German Riesling: Location Matters) But Diploma studies are so much more detailed.

Indeed, this exploration, though it follows the same path, is going to dive a bit deeper and, for fun and educational purposes, I want to actually experience a few of the wines myself to see if I can actually taste what I’m reading about. Hence, “Taste and Learn.”

DipWSET Theory: Winemaking Scenarios

This will be the last post in my WSET Exam-Type Questions series. At least as far as my D1 is concerned. By the time you read this, I’ll have already sat the D1 exam—hope I did ok. Stay tuned, though. D2, 3, 4, and 5 are still ahead of me.

For this last piece, I created two separate winemaking scenarios. To be fair, I pulled certain situations—climactic and soil conditions, wine style type, and even North or South Hemisphere—out of a hat in order to formulate these scenarios. (You know, so I wouldn’t cheat and just ask a question about Sonoma’s Los Carneros AVA and look out my window for the answer.) My goal with these scenarios is to walk through as many steps of the viticultural and winemaking process to prove (to myself) I can talk about all the applicable factors.

Here we go.

DipWSET Theory: Tartrate Stability

First let’s define tartrates. You may have heard them called “wine diamonds.” You can find them on your cork, in the neck of the bottle, and in extreme cases floating in the wine itself (or sunk to the bottom). It’s not bad. It’s just not pretty. Some consumers think it’s a “fault.” It’s not. But to prevent any misconceptions or unhappy conversations, many winemakers will stabilize against them.

What these crystals actually are are deposits of potassium and calcium tartrates. It often happens when a wine (that hasn’t been stabilized against tartrates) sees a dip in temperature—tartrates are less soluble at cold temperatures.

DipWSET Theory: Pre and Post-fermentation Adjustments

[Information based on DipWSET D1 material]

There are certain adjustments winemakers can make to a must wine, pre or post-fermentation. The goal is always to make a more balanced wine, so any and all adjustments should be monitored and measured carefully. Also note that, in many regions, the amount of adjustment(s) that can be made are strictly regulated.

I find I get the pre- and post-fermentation adjustments confused, so thought I’d create a little study guide here. Enjoy.
