All clay-based soils have the potential to change volume and shift with changes in the amount of moisture in the soil-and are sometimes called 'reactive soils' because of this. The amount that soil is likely to shift defines how 'reactive' it's considered to be.
Fortified Wine. Fortified wines are made from a still wine that has additional alcohol added to it, generally bringing the total alcohol by volume to the 17-20% mark. Popular types of fortified wines include: Port, Sherry, Marsala, and Madeira. Made from both red and white wines, with a sweet scene that runs from dry to semi-dry all the way to full blown sweet, the sweeter versions of fortified wines are popular dessert wines.
Types of Dessert Wine Guide. Most dessert wines can be categorized into 5 styles: Sparkling, Light & Sweet, Rich & Sweet, Sweet Red and Fortified. Dessert Wine Basics Sweet wine is produced with extra sweet wine grapes. In order to make them sweet, the fermentation is stopped before the yeast turns all the natural grape sugar into alcohol.
