This top-notch Prosecco winery isn't far off its 100th birthday and was established by Antonio Franco in Valdobbiadene, right in the beautiful heart of the 'original' production zone marked by often steep hillside vineyards at altitude (hence the snowy shot above), which has recently become a much smaller and more quality-focused sub-zone (Prosecco can be made pretty much anywhere in the Veneto region or virtually the entire northeastern corner of Italy it seems). Nino Franco then expanded the family operation and grandson Primo, who's been in charge for over 30 years, has boosted exports substantially - it shouldn't be too difficult to find their wines in your neck of the woods.
The three tasting-noted below are all made 100% from the Glera variety, the 'old' name for Prosecco which has been re-adopted especially in the Valdobbiadene Prosecco Superiore DOCG zone, to make a point of distinction presumably. They're all produced by the 'charmat', 'cuve close' or, less pretty sounding, 'tank' method, where the second fermentation and lees-ageing take place in a sealed vat, then the wine is cleverly bottled under pressure retaining the natural CO2 bubbles. Franco's sparkling wines just go to show that there's Prosecco and there's Prosecco...
These ones are available in the UK/Ireland from JN Wine, Wine Drop and Sommelier's Choice among others starting at £13.50-£14 (€23) up to £25-ish; or Wine.com and many other outlets in the US (from about $18). Photo copied from www.ninofranco.it.
Rustico NV - lively with lightly toasted almond and yeasty biscuit edges, quite intense fruity vs earthy flavours with long crisp vs toasty finish; very nice fizz.
Vigneto della Riva di San Floriano 2013 - more 'vinous' and concentrated, attractive fruity vs baked bread-y mix of flavours with intense bite and length, lingering oat biscuit notes vs fresh and 'salty'; stylish and elegant.
Grave di Stecca 2010 (old steep vineyard, longer lees ageing, only 7 gr/l residual sugar which is pretty dry) - quite rich and toasty with tangy nutty dry mouth-feel, more serious foodie fizz with lovely rounded vs crisp finish.
