I came to know about these aged beef manenos when I visited one of the ranches in Kenya where they keep 9000 beef cattle (yes, nine thousand cattle). They supply their meat cuts to various high end outlets in the country. They slaughter 50 steers each week and the meat is aged in a coldroom within the ranch where it stays for about 21-28 days, or more, under very specific temperature and humidity conditions. The aged beef is then transported using refrigerated trucks to various high end outlets within the country, including tourist hotels, top restaurants and butcheries.

Aged beef is more expensive because during the ageing process, the meat loses about 20% of the weight. Also different cuts have different prices and its true premium cuts like t-bones, rib eye and sirloin steaks can go for upto 2k.

For years I thought that meat from a freshly slaughtered animal was the best quality but the meat expert at the ranch informed me that when an animal is killed/slaughtered, the body stiffens (rigor mortis) and the meat/muscles become very stiff and is very tough even when cooked. During the ageing process the muscles slowly relax and the tough muscle fibres break down while the flavour of the beef increases. So after 21 days of ageing the juicy steak just melts in your mouth.

An interesting thing I also noted is that the ranch has a "bulls quarters", where the champion bulls are kept and each bull is required to mate with 15 cows daily to replenish the herd.

So @njunge pole sana, @matatamingi & other high end customers do not take that lubbish from your village. That trash probably ends up in burma market and then in estate butcheries and later on onto the plates of some middo crass wazuans .

This part reminds me of an instance; we once had a lunch in a Deli,in one of a well known supermarket chain. The beef we ate was extra-ordinary juicy and soft, exactly as @Matatamob has described.
We were convinced it was a combination of 'aged beef' and very good Chef....until after Denis expose.

Kenyans hamna shukrani...After unraveling nasty things eating your country ni 'craft' tena. Jameni?

hajui meaning ya craft, pls forgive him
