There’s  More Than One Vinegar

I am currently  living in what I call Fortress Balsamico. A friend visiting me in Bologna wanted my advice on a distinctive  but not too extravagant Aceto Balsamico to take home – an example that would be exceptional and different from what she would find in Australia. There were seriously too many bottles on the shelves screaming at us. In the end, we could not make a decision and left without a purchase. 

Consequentially, it’s hard to find other artisanal types of vinegar here beyond the cider varieties. When La Cuisine was open, we stocked Spanish sherry vinegar, along with the vinegars from Martin Pouret in France and of course our favorite balsamic vinegars and from Cavalli in Reggio-Emilia. And we also sold some white balsamic vinegars from Acetaia Malpighi  (now frequently called dressings or condimenti since there was a series of noisy flaps over the term “balsamico” used in their production).

But in all honesty, I used to reach for sherry vinegar to brighten sauces and dressings frequently, and in the summer, often it  would be my garnish for cold soups.  It is modestly priced and has a dimension in flavor that is outside of sour – more of a deep hum than a sharp ping. It was my one purchase from Peck in last week’s adventure where I found it neatly stacked in a small selection of alternative vinegars to the Italian anointed Balsamic Madonnas. 

Sherry Vinegar To The Rescue

So what is it about Sherry vinegar, a distinctly Spanish product that I would search out to have in my tiny pantry? Its history is actually fairly recent compared to the true Orleans-style vinegars and the much publicized Italian balsamic varieties. First of all, it is derived from the unique Spanish traditions of Sherry production. Sherry is produced from white grape varieties instead of red, usually Palomino, Pedro Ximenez or Moscatel. This wine is fortified after fermentation and not during, as is done with Port. Fortifying wine is in essence adding a brandy so that fermentation is halted, sugars are increased as well as the alcohol percentage. This method was originally devised to keep wine from spoiling on long journeys. 

Fortifying these wines after fermentation produces a drier wine than Port, which in addition to being vinified from red grape varieties, is fortified during fermentation.  But some barrels in both Port and Sherry fermentation would still be “off” and the contents would be discarded. Whereas the production of Balsamico has a long and almost mythic history in Italy, the development of sherry vinegar was a recent development in Spain. It was not until the 1940s that sherry vintners focused on making a stylish vinegar with these unwanted wines. 

“Sherry,” by the way, is an Anglicization of Jerez, the principal city in Spain’s sherry-producing region. The area roughly forms a triangle on the map.)

The production method, called the Solera System, is an intriguing concept. Picture a stack of barrels: the finished vinegar is drawn from the bottom cask, but only part of it. What’s taken out is replenished from the barrel above, and so on, all the way to the top where the youngest vinegar lives. (Solera means “on the ground,” fittingly enough.) You end up with a beautifully layered product where the old teaches the young—and vice versa. Balsamic producers and whiskey makers use variants of  this aging method.

This solera method  produces three different types of sherry vinegar from two vantage points – the grape used and the aging process itself. The production in Spain is regulated and protected in the EU – PDO for Protected Designation of Origin – which enforces traditional methods and quality- as well as prohibiting imitations of foods and wines outside the awarded area. The US does not have a similar system of regulation and protection of food products, so imitations abound on our grocery shelves. 

NB you will see DOP  (Denominazione di Origine Protetta) on Italian products, which is simply their translation for Protected Designation of Origin.

Pick And Choose

You should note the differences in Sherry vinegars that can be discerned from the label. First of all, if it is made from the Palomino grape, it will be drier and pair well with savory dishes. It’s the one I bought at Peck.   If  Ximenez grapes are the base, it will actually have a sweeter, more raisin-like flavor – it is great for zipping up the flavor of a reduced sauce.   If the label has Moscatel listed as the grape,  then it will be lighter, more ripe fruit than dried fruit in flavor – in Spain it enhances seafood dishes. The vinegar I bought at Peck is aged only for 6 months and is good for salads and marinades. I would love to get my hands on a Sherry Riserva that has been aged for at least two years as you can tell the difference when it is added to sauces. I have only tasted a Sherry Gran Riserva at a food show. Sort of caramel and dried fruit together in terms of flavor. Gran Riserva Sherry Vinegar is aged for over ten years. 

 Unlike true Balsamico vinegars, Sherry vinegar really plays  well with others. You can use it with lemon juice in a marinade, or add it to whatever green sauce is your favorite (it seems almost every Western cuisine has one). It just gives more body, more oomph.  Most gazpacho recipes will require an  addition  of  sherry vinegar, but it’s great for potato salads, and does a genuine service when added to your stuffing for deviled eggs. 

Below is a recipe for a cold asparagus soup  from Ottolenghi’s cookbook Plenty when it was published in 2010. I added sherry vinegar to it as a drizzle instead of the yoghurt that he suggests. Use the the big woody asparagus for this, (yes this is a great recipe for those wasted asparagus ends) but as you know from my previous asparagus post, I always peel mine.
