At Voskevaz you definitely need to book in advance. Here is their phone number: +374 99 550970.

I just spoke with them — it’s better to book a couple of days in advance, but if there are only a few of you, you can also come on the same day. The cost is 3,000 drams per person (≈ $7.5) for just a tour, and with a tasting it’s from $40 to $100 per person, depending on the number of wines and the category. Better to call — they’ll explain everything in detail.

We first took a taxi to some industrial area and were shocked that a winery could be somewhere there, but actually inside the building it’s very nice — a cool cellar, an interesting tour, and tasty wines. Visiting wineries with vineyards is especially great in spring, when there’s not yet unbearable heat.

do taxis easily go outside the city?

They go anywhere without problems. Just set the taxi to wait and return with the same driver, because from the wineries you might end up waiting a long time for a taxi back.

Also Tushpa Wine Cellar — good wines and tasty food, though it feels like they’re already a bit tired of visitors.

Ah, and also Voskevaz Winery — they built it like a castle. There’s no vineyard there, but in this kind of weather it’s just perfect. And the wines are good too.
