If you consider Champagne the only "proper" fizz, then look away now.
There are plenty of other fizzes apart from Champagne - they all do different things and occupy different price points.
Ukraine's sparkling wines are at their best enjoyable, inexpensive sparklers with plenty of character.
Artemovskoye White Semi-dry, 2015 a blend of Riesling, Aligote, Pinot and Chardonnay grapes and has a year's ageing on the lees plus some further bottle age. Plenty of aromatic and floral zip, with lemony-sherbet fruit, a bit of leesiness and a pleasantly off-dry finish to round off any rough edges.
What's not to like?
Drink as an aperitif or with match with starters such as mozzarella or seafood.
