I am new to brewing and received a Hard Cider kit for Christmas. After brewing in the fermenter, I bottled it in the provided one liter bottles with 2.5 tsp of table sugar. After sitting for two weeks, I decided to refrigerate and try a bottle. Although it tastes good (although a bit weak which is probably why the refill kits come with an extra bottle of concentrate), it really isn't carbonated. There was a slight fizz when I first opened the bottle but there are no bubbles when I poured it. I know the instructions say it should sit in the bottles for 2-3 weeks so maybe I should have waited longer. Does anyone that has used the cider kit have any suggestions or advice? Thank you.
