I want to know too.

What i heard is the more heavy it is, the more JUICES.

go to those old unker or aunty stall ask them pick for u
and not those hot chick at the roadside of tambun

Ipoh pamelo sell in ipoh normally doing traveller business.....in other words: chop head
Better off buy local biscuit instead of ipoh pamelo unless u know someone familiar in ipoh.

Go to Jalan Ampang or Pasar Basah Ampang Ipoh ... Used waze... That the place u no need sakit kepala to search for good pomelo... The price was reasonable...

My mum teach me to used ur finger ketuk ketuk the pomelo ... The heavy sound the better ... Less sound means the skin is thick ... Juz how u choose water melon ...

Not sure if its true or not but this is what someone from perak told me.

Always buy Tambun pamelo, chances of getting sweet one is better compare to other part of Perak's pamelo.

Choose the one where the bottom (center) is not protruded but with a depression (like in most oranges), high chances it will be sweet. If bottom protruded, mean sour.

This i try on oranges but not pamelo before. So one hv to try it to see if its true.

Cant believe noone here actually knows how to pick good pamelo.. Myself already a good picker, learn more and compare, then you will get answer. To pick a sweet a good fruits is very easy for me unless watermelon.. That one got water also not mean sweet one, have to listen to the sound and the skin.. Quite hard

No need to know which farm to harvest as u are not picking ur future wife... Make it simple n don complicated it orelse next year CNY also no pomelo for you ...

FYI ipoh pomelo mostly from Taiping, Kedah .... U still able to get genuine Ipoh Pomeloes in Jalan Ampang Ipoh waze ampang pasar ipoh) ... At least 5 to 6 store selling pomelo but the distance between the store quite far away la...

Don worry about sour or sweet pomelo... This the seller wont cheat you ... The oni thing is taste good onot ... Ask the seller, can this eat immediately o have to wait how many day to eat baru sedap...

Lol, seriously, like I said, someone told me that and I am not very sure myself because unless I did passes by Ipoh/perak, else I seldom buy them.

You have to try those method to know if its true.

Anyway, below is a link I found in the net

Red pink definitely is sour ... Normally the sour one is bigger size n the skin is thick ...

How many days u keep be4 u eat ? Tat is y i m asking u to ask the seller how many days able to keep n what the best time to eat .... Farmer normally plug the pomelo before masak ... Eat too early tak boleh eat too late will dry ... So ask them ...

Again if you are buying it in ipoh, go to Jalan Ampang Ipoh... Most of the seller is aunty n uncle ... Don ask ah moi or ah jai which no experience ... Other places in ipoh either chicken chop u or tong simen you ...

FYI : there is not many tambun pomelo available in the market ... All i can said is, go to Jalan Ampang Ipoh to look for pomelo as that the places sell Tambun pomelo ... Y ? Coz tambun town is next to Ampang town
