You are right, but a weak currency can wreak havoc as well - let's not forget that after Bulgaria's hyperinflation in 1997, the Lev was pegged to the Euro. Effectively, we've been using the euro for 19 years now.

Hmm... I'm more of a red wine fan. Bulgaria produces both one of the best and worst wines in the world. As a general rule, never buy any Bulgarian wine under 10 euro. There are a few exceptions - try to find Terra Tangra wines - the 2012 selection of Malbec & Cabernet Sauvignon, currently on the market, is excellent at around 6 euro per bottle. Enira (Brass Valley), Stallion, Nimbus and Twins wines are quite good as well, although pricier.
