I asked Anthropic's Claude,
"What are the best varieties of grapes to plant now in Ireland for wine production in ten years' time?"
This how Claude responded:
For wine production in Ireland over the next decade, you'll want to focus on cold-hardy, early-ripening varieties that can handle the cool, damp climate while still producing quality fruit. Here are the best options:
Top Recommendations
Solaris — The most widely planted wine grape in Ireland. German-bred hybrid that ripens early, resists disease well, and produces aromatic white wines with good acidity. Ideal for Irish conditions.
Rondo — A reliable red variety that's cold-hardy and disease-resistant. Produces deep-coloured wines, though often blended due to its tannic nature.
Regent — Another solid red option with good mildew resistance. Produces softer, more approachable reds than Rondo.
Seyval Blanc — French-American hybrid that's well-established in cool-climate viticulture. Makes crisp, citrusy whites and handles Irish weather well.
Madeleine Angevine — Early-ripening white that performs well in marginal climates. Light, aromatic wines.
Bacchus — If you have a warmer, sheltered site (south-facing slope, good drainage), this aromatic white can work. More demanding than Solaris but produces excellent quality.
Practical Considerations
Site selection matters enormously — south-facing slopes with good drainage are essential. Wet feet kill vines faster than cold.

Climate change is shifting possibilities — warmer temperatures are expanding what's viable in Ireland. Some growers are experimenting with Pinot Noir and Chardonnay on the best sites.

Disease resistance should be a priority given Ireland's humidity — hybrids bred for resistance (Solaris, Rondo, Regent) will save you significant headaches compared to traditional vinifera varieties.
For a ten-year horizon, I'd plant primarily Solaris for whites and Rondo or Regent for reds, with perhaps a small experimental block of Pinot Noir if your site is exceptional.
Happy St Daria's Day (by the old Julian calendar).
