The outside of the bulb is brown at the top, but the cloves look and feel normal when peeled.

enter image description here

Is this safe to eat? What is the reason for the brown colour?

Your garlic is fine, some discoloration of the outside layers is normal. When garlic is lifted out of the ground it's covered in dirt and the outer layers are brown. Garlic is then cured (it's just letting it dry for a few weeks, there's no salt or chemicals involved) which prepares it for long term storage, during this process the garlic skin dries. Often the outer layers are peeled off to make the garlic look nicer, and depending on the variety these are usually white or white with purple.

The more layers you peel off the less protection garlic has for long-term storage, at some point you have to stop peeling or it won't last. In the case of your garlic they stopped peeling when there was still a bit of brown, which was the right thing to do. It's just appearance.

Garlic can look all brown and gnarly and still be absolutely fine, it's the condition of the cloves once peeled which matters. If the cloves themselves are discolored, soft or look rotten then they aren't good to eat.

    Garlic is cured? As in salted and smoked?! – Janus Bahs Jacquet Sep 01 '23 at 08:33

    @JanusBahsJacquet from a quick google it appears that in the context of garlic processing, curing just refers to drying out the outer layers, rather than using chemical preservatives (like salts and nitrates) as it typically does. I will note that smoking is normally considered an additional process that may be done in parallel with curing, but is certainly not required (e.g. parma ham is a simple salt-cured ham that is unsmoked) – Tristan Sep 01 '23 at 09:01
  • @JanusBahsJacquet I grew garlic this year in the garden, you just need to let them dry several days in the sun so that it doesn't rot once stored – Kaddath Sep 01 '23 at 09:33
  • @Kaddath, a few days isn't enough, full curing takes at least 3 weeks, often longer depending on temperature and humidity. A few days is enough to get it started, then you can braid it and it will fully cure hanging up in your kitchen. – GdD Sep 01 '23 at 10:47

    Sorry for the confusion @JanusBahsJacquet, as Tristan says curing just means drying. I don't know why it's called curing, it just is. I've edited the answer to make that clear. – GdD Sep 01 '23 at 10:51
  • Excellent video on All-Things Garlic, including the curing process and more. - https://www.youtube.com/watch?v=WgES_Oj6-tQ – SnakeDoc Sep 01 '23 at 16:18
  • @GdD you don't leave them 3 weeks under the sun, no, they would become garlic mummies (here in the south west of France it's really hot and dry when you harvest them), you put them in a shadow and dry place once braid – Kaddath Sep 01 '23 at 16:25
  • Indeed, moving them into the shade as soon as possible after harvest (to the point that real farmers tend to use wagons with shade covers while in the field) is the norm. Note that braiding only applies to soft-neck garlics. Hard-necks don't braid. – Ecnerwal Sep 01 '23 at 16:41
  • That's not true @Ecnerwal, I've braided hardneck varieties for years, they braid absolutely fine. The trick is to braid them before they dry out too much or they get too stiff. – GdD Sep 02 '23 at 18:25
  • I never said you leave them in the sun for 3 weeks @Kaddath, I said you cure them for at least 3 weeks. – GdD Sep 02 '23 at 18:27

Dirt, or oxidation would explain the brown color (dirt if it's always been this way, oxidation if it's changed. Garlic grows in the dirt, and if it's not harvested early enough to have plenty of dirty leaves to strip off the bulb while clean leaves remain below them, it may well be stained with dirt. Or if it simply wasn't stripped of the outer leaves after harvest for that purpose.)

There's nothing wrong with that garlic from this picture. It should be perfectly safe to eat.
