There is a requirement that "shevi'it" produce be consumed for personal use and cannot be sold or put in trash. For this reason, there are various special rules regarding the religious use of products that are normally made from agricultural produce. Some authorities hold that Hanukkah candles cannot be made from "shevi'it" oils because the light of Hanukkah candles is not supposed to be used for personal use, while Shabbat candles can be because their light can be used for personal use. For similar reasons, some authorities hold that if the Havdalah ceremony is performed using wine made from "shevi'it" grapes, the cup should be drunk completely and the candle should not be dipped into the wine to extinguish the flame as is normally done.
