We’ve just returned from a few days in Germany visiting the famous wine regions of the Rheingau and the Mosel. Of course, I’d seen lots of pictures of the area and read plenty about it, but this was my first visit and I was truly amazed by what I saw. Wherever I looked, there were vines clinging to impossibly steep hillsides – some up to 65% elevation. How can people possibly work those sites? And why do they choose to plant there?
The answer to the first of those questions may be obvious: with great difficulty! There are posts at the top of some of the vineyards that workers can tie ropes onto and let themselves down to prune the vines or harvest and, in some of the more high-tech places, you find miniature monorail systems that run up and down the slopes to carry the grapes to somewhere slightly more accessible.
But why plant on these slopes? The area is at the northern-most boundary of where wine grapes will ripen properly so growers have to take every opportunity to help the vines. Using south-facing slopes gives better exposure to the sun and protection from cold north winds. The slopes mean that rain drains quickly so that the vines’ roots are in warmer, dry earth and frosts roll away down the hillside; also much of the ground itself is comprised of decomposed slate which acts like a storage heater and holds the heat.
Even with all these advantages, growers still need to choose a variety that will survive the bitterly cold winters. And, for most, the one that works best is Riesling. It’s a grape that many in the UK avoid but, for me, apart from the very cheapest examples, it’s a variety that can produce some remarkable wines. I’ll tell you more about them in my next blog.
