We recently discovered this wonderful producer of Balsamico at a recent Salon del Gusto in Turin Italy. In addition to their Aceto Balsamico Tradizionale di Reggio Emilia they produce a number of other amazing balsamic products including this agro di mosto.

Agro di Mosto is similar to Saba in that it is made from the same cooked grape must (Lambrusco and Trebbiano grapes) used for producing balsamico by reducing by 1/3 over an open fire which caramelizes the sugars and concentrates the flavors. Following this common beginning, agro di mosto is fermented and aged in the first barrel of the balsamic production for 2 - 3 years.

Agro di mosto has therefore still a good bit of the sugars that it started with, but it has also started to develop some of the tanginess you will taste in the older balsamics. We love to use this when we are building a reduction sauce.

About Acetaia San Giacomo:
We recently discovered this wonderful producer of Aceto Balsamico Tradizionale (ABT) di Reggio-Emilia at the Salon del Gusto and we are happy to have it on our shelves in time for the holidays. The tradizionale vinegars are all of a minimum level of quality as defined by the consortium and while it would be easy to then consider all such vinegars equal, there can be distinct qualitative differences from one producer to the next. Our vinegars are from a small producer who reaches beyond the consortium's requirements to produce the best traditional product they can. This means choosing only the highest quality grapes for pressing and cooking; cooking the mosto at a lower temperature for a longer period of time; maintaining
a low residual sugar content so that the full complexity of flavors comes through and the vinegar is only aged and stored in wood and never in steel. We have a wide selection of vinegars including the Aceto Balsamico Tradizionale in red seal, silver seal and gold seal as well as their saba, vincotto and condimento balsamico.  For more information on balsamic vinegars, please visit our balsamic education page

Acetaia San Giacomo

We discovered this wonderful producer of balsamico at the Salone del Gusto in Turin Italy. Andrea Bezzecchi produces his vinegars in Reggio Emilia which is just Northwest of the more well known town of Modena. Andrea set a new standard for balsamic vinegar by using exclusively cooked grape must as the base of each vinegar. By comparison, Aceto Balsamico di Modena allows use of up to 40% wine vinegar which is a substantially less expensive ingredient.

While this is the standard for the highest level Balsamico Tradizionale di Reggio Emilia, it is not typically found in younger vinegars.

The result is a range of vinegars with a balance of fresh fruit character and deeply aged vinegar flavors.

Andrea chooses the best Italian grapes from his region and gives each batch undivided attention as the must is cooked, fermented, acetified and aged.

Vinegar Use and Care

Caring for Your Vinegar

What is vinegar?

Vinegar from the French Vin (wine) Aigre (sour), as with many delicious food products comes to us by way of gradual chemical changes resulting from exposure to natural elements such as time, bacteria and oxygen. Yet you'd be mistaken to consider the process of making fine vinegar as simply letting some wine sit out on your counter for a month or two.

Does vinegar go bad?

Caring for your vinegar is pretty simple but there are a few things worth noting. As with many products, the texture, flavor and aromatics of vinegar will change with extensive exposure to heat and light. While it will not technically "go bad" we find that well-stored vinegars maintain the flavors we expect much better than those that might be kept near a hot stove for several months.

Is vinegar sediment ok?

Some vinegars will have a bit of sediment at the bottom of their bottle. This will be the case for unfiltered vinegars and also can happen with vinegars that have been in storage for a long period. This sediment is not harmful and the vinegar will still be good to the last drop.

How is vinegar made?

The most ancient method of vinegar production is today called the continuous method, the surface method, or the more well-known, Orléans process - named after the French city of Orléans which was the center of French vinegar production in the 16th century.

This process is difficult to manage and maintain consistency and it takes a lot of time from raw materials to finished product. We work with a vibrant community of artisan producers committed to producing exceptional vinegars using this more time consuming and labor intensive method.

Most vinegar you'll find in supermarkets is produced using the modern innovation of 'submerged acidification' using industrial acetators to produce vinegar in a matter of hours. These vinegars are functional and inexpensive, but they lack any aromatic complexity and offer limited gastronomic value as compared to the more traditional vinegars.

How do I use vinegar?

Using your vinegar is easy... you likely have your favorite recipes, but here are a few ideas we love:

  • A splash of vinegar in sparkling water for a refreshingly vibrant spritz
  • A drizzle of balsamic over sliced fresh figs, a hunk of Parmigiano-Reggiano or a bowl of vanilla ice cream
  • Quick pickling of vegetables by cooking a solution of vinegar, water, sugar and spices - cool and pour over the cut vegetables and set in fridge for a day
  • Add a dash to finish your pasta sauce (balsamic) or your gazpacho (sherry vinegar) for an added dimension of brightness
