I get this one from new cigar smokers all the time.

Question: Does the size of the cigar make a difference?

Answer: Yes.

A cigar is a blend of three main parts, all of which come together to give you the flavor of a cigar. The three parts are the wrapper, binder and filler. The smaller the cigar the less of each three parts used. The larger the cigar the more of each three parts used. Therefore, the flavor of a 46 ring gauge cigar will differ from a 56 gauge cigar. There are many factors, below are two major ones.

The Filler: The larger the cigar gauge the more filler is required. This changes the flavor of a cigar because there is more tobacco filler burning. Typically, smaller gauge cigars have stronger flavor and larger gauge have less.

The Draw: Larger gauge cigars allow more air to flow through while drawing. This changes many things (too many to get into) but the main factor is how quickly the cigar burns. A faster draw leads to more air. More air leads to faster burning. Faster burning leads to a different taste and possibly a harsh flavor from the cigar.

Again, there are many - many - factors that come into play regarding flavor and size. But, to me the above two are key. I'm sure others can elaborate.
