Part 3 of series on the wines of the Balkan States and former Yugoslavia: Bosnia-Herzegovina. A small wine industry, with just 3,500ha of plantings but 11,000 growers. The main regions are around Mostar between the Adriatic Sea and high central mountains. It's still not a fully regulated industry, but there are a number of indigenous grape varieties which make the wines of current and future interest.

Episode 2 of my series on Balkan wine: Croatia. A beautiful country which attracts two and a half times as many tourists as residents, the wine regions can be divided into coastal and continental inland. There are some similarities with nearby Slovenia, Italy, Austria, and Hungary, as well as international varieties and those unique to Croatia. A fascinating wine country which is rightly gaining some more attention.

First episode on the wines of the Balkan States, starting with Slovenia, a country with lots of connections with neighbouring regions of Friuli in north-east Italy and Steirmark in southern Austria. The climate changes from Mediterranean on the coast to continental further inland, leading to a variety of styles. There's also the tradition of skin-contact white wines, which has been influential around the world. A country whose wines are well worth exploring.

250 indigenous varieties plus a handful of international; different names for the same variety, named after animals, people, and often hard to pronounce; field blends in a small, fractured vineyard ownership; maritime and continental climates: for such a small country, Portuguese wine is hard to pin down, but an understanding of the varieties helps. Here's an overview of some of the major white and black varieties and the regions they're grown in to gain a sense of Portuguese wine.

This episode explores some of the 40 grape varieties approved in Austria, including the classics such as Grüner Veltliner, Blaufränkisch, St. Laurent, and Zweigelt, lesser-known but historic varieties such as Welschriesling and Rotgipfler, and international varieties Chardonnay, Sauvignon Blanc, and Pinot Noir.

Conversation with Sheila Donohue of Vero Vino, who specialise in importing "scarce and wild" Italian grape varieties. We discuss four lesser known—or completely unknown—varieties local to their regions : Schioppetino, Boschera, Famoso, and Durella. Expect lots of acid talk!

Interview with three Cava producers on its identity and what makes the sparkling wine different from others: place, grape varieties, ageing, and its history. Cava has introduced labelling terms and regional designations which allow producers to talk about exactly where the wines come from than before. Interviewees: José Maria of Vins Familia Ferrer, Mereia Pujol-Busquets of Alta Alella, and Marta Casas of Parés Baltà.

Just back from a two-week trip to Australia where I visited the wine regions of Tasmania, Adelaide Hills, and McLaren Vale. The former two are relatively young with lots of development over the last three decades; they're also cool climate with fantastic sparkling wine. McLaren Vale is more historic, but also with lots of changes since the 1990s.

What's the difference between an Old and a New World Wine? Is there a differerence? This episode explores what the terms mean, whether we should use them, and how they can be an easy way into describing the wines of a prominent country? What the episode does not answer is whether England is New World or Old World!

There are many historic grape varieties from southern Italy, which are deservedly regaining attention. This episode looks at some of the black grape varieties across southern Italy, as well as Sicily and Sardinia: Agliancio, Negroamaro, Primitivo, Gaglioppo, Nero d'Avola, Nerello Mascalese, and others.
