Dear sir,
Thank you for your excellent guide to winemaking onyour site.
In fact I have problem in my country and I do not knowhow to solve it.
Kindly Help me to find a solution.
1-In my country it is very difficult and expensive to
get large glass containers like demijohn.
Is it possible to use a normal plastic bottles
(PET)instead.?(i.e. the 1.5 litre plastic Coca Cola Bottles.
2-It is very hard to find Campden Tablets and Pectozyme
.I purchased some tablets (cholor based for strilising
water but its name is not "Campden".
I also do not know What to use instead of Pectozyme).
3-The only Yeast I could find is the ACTIVE Yeast granols for bakery.
How much should I solve into the must?
4-What should I use instead of nutrient for Yeast?
I have got about 100 kg. of grapes (3 kinds) and put
half of them into one plastic container. So since I
have started the job Kindly help me not to get intomess!!!Thaks a lot again.
