I'm a 1st. timer. I made some wine from jam following exactly CJJ Berry's recipe. The tem of the fermenter was 26-28 on the heat strip. Started at 1.090 and ended at 1.040. How can I make it stronger. I added re-start yeast at 1 gram per gal but no change. Thanks in advance for any advice

I have never made wine before. I made some from jam exactly to the recipe in CJJ Berry's book. It's only 6.5%. What can I do to make it a reasonble strength. Thanks in advance for any advice offered.
