ok i have tried three mixtures and got same results..... only time bubbles come from bottle are when i shake it up then bubbles roll out fast. then die and stop bubbles all together. I found a leak in top so i made new one and resealed it. i have tried 1 tsp of yeast with 2 cups sugar and no bubbles. I store yeast in fridge when not using per instructions on bottle of yeast. I am using activated dry yeast. What is considered too hot for the water levels? I go till water feels warm to me and add to bottle... should i turn water hotter or colder?
