It's the other way round.
Unless you do want Grape infused cigars...
If you do want such, I believe you can some already so infused.
Save yourself some money, and you avoid becoming a wino too.
Now here is the easiest way to do this.
Do not smoke any cigars that have larger ring gauges,you would either crush them or,
have to cut them down in size, this could well have a negative effect on how they smoke.
Do use only cigars of the smaller ring gauges which you can easily slip into a wine bottle.
Note you need to uncork or unscrew the bottle first.
Caution, if you break off one end of the wine bottle not 0nly will you have to live with the smell.
but the cigar will keep moving about resulting in uneven infusion.
The wine could evaporate before you are ready to smoke that cigar, and you end up with a dried out cigar.
One final tip, if you think the wine bottle is too full to allow the cigar to placed in there before resealing.
Pour some the wine out into an ashtray or other container then discard outside well away from the house.
