As an expert sommelier and brewer, I can certainly provide you with some insight on using vermouth instead of white wine in risotto. Personally, I think using vermouth can be a viable substitute, but there are a few factors to consider.
Firstly, let's talk about the flavor profile of vermouth. Vermouth is a fortified wine that is infused with various botanicals, herbs, and spices. It typically has a slightly sweet and floral taste, which can add a unique dimension to your risotto. However, this sweetness and floral character might not always work well with certain risotto recipes, particularly those that require a more savory or acidic flavor.
If you decide to use vermouth, I would recommend opting for a dry or extra dry variety. These types of vermouth have a lower sugar content and are less sweet compared to sweet vermouths. Dry vermouth can provide a more balanced flavor and complement the other ingredients in your risotto without overpowering them.
In terms of quantity, you can use vermouth in the same amount as you would use white wine in your risotto recipe. However, keep in mind that vermouth can have a more potent flavor, so you might want to start with a slightly smaller amount and adjust to taste as you cook. Remember, it's always easier to add more later if needed.
One advantage of using vermouth in risotto is its longer shelf life compared to white wine. Vermouth can be kept almost indefinitely, while white wine typically has a shorter lifespan once opened. This can be particularly useful if you don't frequently cook with white wine or if you have a bottle of vermouth on hand that you'd like to use up.
Now, let's talk about some personal experiences. I once experimented with using vermouth in a mushroom risotto, and it turned out quite well. The floral and herbal notes from the vermouth added a unique depth of flavor to the dish, enhancing the earthiness of the mushrooms. However, I wouldn't recommend using vermouth in a seafood risotto, as the flavors may clash.
Using vermouth instead of white wine in risotto can be a delicious alternative, but it's important to consider the flavor profile and the specific recipe you're using. Dry vermouth is generally preferred, and you may want to start with a slightly smaller amount and adjust to taste. Remember, personal preference plays a significant role in cooking, so feel free to experiment and adapt the recipe to your liking.
