We made a peach wine from a box kit in the store. This wine is a mist so the ABV is lower than regular wines but much more flavorful. Increasing the ABV is very simple; simply add more fermentable sugars to the wine during fermentation. Please contact us before you do this so we can discuss the amount of sugar to use. We always recommend no more than 2.2 LBS or 1 KG, The process we used was directly from the written instructions in the box. No need to buy anything extra; this kit comes complete. We also used the fastferment to make this wine to highlight its use and simplicity. Check us out at www.barleyandhopsbrewing.com or like us on facebook.
