Master of the Brew

Lets begin at the beginning; In order to obtain this Achievement we first need to have a [skill=185] level of 530. There are plenty of guides explaining how to get there, so I'm not going to repeat them here. Once we have obtained 530 in cooking, we then must proceed to [npc=64231] who is found at Halfhill in the Valley of the Four Winds, next to [npc=60231] allowing for easy access.

[npc=64231] is a [skill=185] Trainer, who has recipes that allow you to obtain 530 if you're not quite there as well as selling the ingredients needed for those recipes. She offers a total of 9 quests, only three of which we have to worry about for this Achievement.

1) So You Want to Be a Chef...
Simply buy 5x Pandaren Peach, learn Sliced Peaches and cook them. Hand them in and get the next quest:
2) Ready for Greatness
Simply buy 5x Rice & 5x Yak Milk, learn Rice Pudding and cook them, upon completing this quest the 6 "Way of..." quests become available, we want Way of the Brew for this Achievement.

Way of the Brew requires that we buy 1x Ginseng from [npc=64231] and hand it into [npc=58717] who is located within the 'circle' of Cooking Masters to our right when facing [npc=64231]. Upon completing the quest, [npc=58717] will return our Ginseng and present us with a new quest: [quest=31480]; First we have to learn the recipe Ginseng Tea from [npc=58717] and then 'cook' a Ginseng Tea before presenting it to him.

Now we are into the unguided section, there are 5 Brew recipes, only 3 of which are needed to hit a skill of 600. Given the easy of obtaining Ironpaw Tokens, I shall be referring to them in this guide.

Buy 19x Ginseng from [npc=64231] and make Ginseng Tea until skill 550, easy.
Return to [npc=58717] and learn Jade Witch Brew
Witchberries can be Looted, Harvested via Witchberry Seeds or bought with one Ironpaw Token from [npc=64395] who sells [item=87712].
Jade Squash can also can be Looted, Harvested via Jade Squash Seeds or bought with one Ironpaw Token from [npc=64395] who sells [item=87713].
We will need 6x Ironpaw Tokens to buy 3x [item=87712] & 3x [item=87713], make [item=75037] until reaching a skill of 576, this should only mean making 13, but mileage may vary. Extras can be stored or sold, what ever you wish to do.

Return to [npc=58717] and learn Banquet of the Brew
We know how to obtain Witchberries (see above), Green Cabbage follows the same logic Green Cabbage Seeds and [item=87706].
100 Year Soy Sauce can only be obtained via Ironpaw Tokens.
We will need 5x 100 Year Soy Sauce, 250x Green Cabbage & 250x Witchberries that is a total of 25x Ironpaw Tokens, we should only have to make 5 lots of the Banquet of the Brew (5 per lot) to hit our goal of 600 skill points in the Way of the Brew.

We will have used a total of 31 Ironpaw Tokens to go from 530 to 600, but you may reduce this number by Looting your own ingredients or Harvesting them on your own Farm.

Materials Needed:
_25x Ginseng -Vendor Bought-
__5x 100 Year Soy Sauce -Vendor Bought only with Ironpaw Tokens
_65x Jade Squash -Vendor Bought with Ironpaw Tokens, Grown with Jade Squash Seeds or Looted
315x Witchberries -Vendor Bought with Ironpaw Tokens, Grown with Witchberry Seeds or Looted
250x Green Cabbage -Vendor Bought with Ironpaw Tokens, Grown with Green Cabbage Seeds or Looted

With all luck, we should now have this Achievement and be considering how to work on the other five; Master of the Grill, Master of the Wok, Master of the Pot, Master of the Steamer, Master of the Oven to finally gain Master of Pandaren Cooking and the title [title=315].

Happy Cooking

To save time/mats make Ginseng Tea till 550 then make [item=75037] till 576 then make 3 [item=87248] , going to 551 with Ginseng Tea will mean [item=75037] will go grey at 575 meaning you will need to make 5 small or 4 large feasts to max your Way of the Brew.

If you are pandaren you need to obtain 615 skill points in the Way of the Brew to get this achievement.
