Is the size of a cigar important to the taste and aroma?
Yes, the same cigar blends in different sizes will taste different if there’s a big difference in ring size and length. This is because a big ring gauge, say 50 or 52, produces an immense volume of smoke compared to a 28, 36 or even a 42 ring. Larger ring gauges allow for more filler tobacco which gives a cigar more complexity and allows the cigar to burn slower and cooler. Naturally, this strongly influences taste and aroma. To fairly compare two different blends, you should taste test cigars of the same size.
To a lesser extent, length also influences taste. Besides, if you start with a 7 inch cigar when you’re used to one 5 1/2 inches long, it’ll become 5 1/2 inches long soon anyway – although, believe it or not, the 7 inch cigar at 5 1/2 inches will taste a little different than the one that starts at 5 1/2 inches.
If a manufacturer excels at making a great cigar 42 ring x 6 1/2 inches, it does not necessarily follow that the same brand in other sizes will be as good or as consistent. You’ll have to try a box of each. If you’re not accustomed to smoking a certain size that you might be curious about, maybe you should enlist the cooperation of a friend who smokes that size regularly.
