Since 2000, Habanos launched every year Limited Editions cigars (Edicion Limitada), introducing to the market cigars not in regular production, in limited quantity, of course, as the name says. Usually these cigars have been issued for the most well-known brands (Cuaba possibly being the exception with their 2008 Piramides).
I understand that initially they were made using regular tobacco and with two-year old tobacco for the wrapper, which was also selected from the upper part of the plant (was it the famous medio tiempio tobacco currently used for the Behike? We will never know! :) ). However, since 2007, all the tobacco used in Limited Editions is at least two-year old. This should contribute to a more enjoyable cigar as the tobacco has had longer time to develop its unique flavour, although not in an assembled cigar (which means that it may still be good not to smoke Limited Editions straight away).
Over time, there have been some magnificent Limited Edition. One I'd certainly like to mention is the Partagas D No. 1 from 2004. Or maybe the Montecristo Sublimes from 2008 (by the way, I felt that these cigars were really good when they first came out, they then lost somewhat strength for a couple of years but they seem to have gained again in flavour over the last 12 months... the power of aging!)
In 2011, Habanos issued three Limited Edition. In classic cuban style we only saw some of them in 2012 but here they are in the picture below:
They include:
1) Hoyo de Monterrey - Short Hoyo Piramides, a 5 3/8 inches long, 46 ring figurado
2) Ramon Allones - Allones Extra, a 5 5/8 inches long, 44 ring gauge
3) Cohiba - Cohiba 1966, measuring 6 1/2 inches long by 52 ring gauge
They are still relatively fresh and they need further time to develop. Generally, I have not been too impressed by them, particularly the Allones Extra which seems to be very much a hit or miss (ie they don't seem to have consistent quality). The Cohiba - which name was chosen to commemorate the 45th anniversary since the launch of the brand - seems to have great potential but it needs a bit of time and it certainly comes at a significant price. The other two are interesting because the Hoyo is a bit stronger than the traditional Hoyo while the Ramon Allones is a bit lighter than the traditional Ramon Allones. But then, why would I buy a Hoyo or a Ramon Allones? I think I'd rather have brands that stick to what they are good and known for, but perhaps time will prove me wrong and with aging I will be praising all of these cigars... In the meantime, I would suggest to stock-up if you can, particularly on the Cohiba. You can most likely expect those prices to go up and once the cigars have run out you will find some major aficionado (or some wealthy newcomer) ready to spend money to still smoke them (assuming that you will have the strength to sell them!). Enjoy!
