Are you a Filipino? Yes? Do you want to get a pure and good quality yeast for wine making venture? Yes? Then you might find it hard to get one! The active dry yeast is a common product. It can be bought in most supermarkets, large groceries, bakeries and bakery supply shops. However, this active dry yeast is not meant for wine making. This variety is specially cultured for bread making. Based from my own experience, the resulting wine quality is inferior and has a bready taste and aroma. The variety specific for making wine is not locally available. Not available as of writing this. Hope someone take the initiative of manufacture.
Here are some ways to get it. 
1) The hard and costly identification and isolation method. You read it right, identify and isolate your own wine yeast. Study hard until you are well versed with all the physical structures of all valuable wine yeast. Study microbiology techniques. Then invest in a clean room with all the equipment needed. You are now ready to do it. For the start – get some fruits and let the natural fermentation commence.
Good luck! Who knows, you might discover a new variety that can produce 70% alcohol.
2) The method 1 is for serious scientist. Why do the hell of identification and isolation if you can buy a pure culture from a university laboratory or other private institutions. The next phase is less of burden. Multiply the pure culture using appropriate media.
3) If you have the means, it can be bought online. Buy pure and dry cultures from eBay, Amazon and or online shops. Most sellers accept credit cards and paypal. The dry culture can also be multiplied using appropriate media.
4) If you have a relative or close friend living in United States or other countries where wine making is a popular industry, then ask him to buy some dry culture for you.
5) Befriend a man who is into wine making business. Then ask him to share some cultures. Unfriend him if he refused. Ha! ha!
