2,888. What Products Combine for a Nazir

Hilchos Nezirus 5:3

All of the prohibited parts of the grape combine to form the volume of liability. Accordingly, if a nazir combined fresh grapes with raisins, unripe grapes, seeds or peels, and he ate an olive-sized portion, he is liable. The same is true if he ate such things in succession until he ate an olive-sized portion in total. He would also be liable for drinking a reviis of wine and vinegar combined.

Hilchos Nezirus 5:4

Something permitted doesn’t combine with something prohibited in order to render a nazir liable. Therefore, if wine is mixed with honey so that it tastes like wine and a nazir drinks it, or if raisins were pressed with figs so that the raisins could be tasted and a nazir eats it, he isn’t liable to lashes unless (a) there was an olive-sized portion of grape in a mixture the size of three eggs and (b) he eats the volume of three eggs. This is the general law when it comes to prohibited foods, as was discussed in Hilchos Maachalos Assuros.
