While no drink provides an instant erection, some beverages support blood flow and cardiovascular health, which can improve erectile function. Apple cider vinegar, often abbreviated to ACV, is amber or dark-brown liquid made from apple juice. To make apple cider vinegar, apples are first pulverized to collect the juice. This juice is then added to a bacteria-and-yeast mixture which triggers the sugars in the apple juice to ferment. This first fermentation causes alcohol to form. The alcohol is then further fermented to form acetic acid or vinegar. The acetic acid gives apple cider vinegar its distinctively sharp taste and scent.
