It depends on your goals. Just my 2 cents here: The higher the alcohol content, the "hotter" it will taste and longer it will take to be drinkable. For your first wine, I'd recommend you try a lower ABV, that will be drinkable sooner. Otherwise, you make a strong batch, and will be itching to try it, then when you cave and drink it soon itll probably be disappointing and you wont be as eager to make the second batch.
Get your pipeline full with some quicker, less strong wines so you have SOMETHING to drink and marvel at how good it is, before you start trying to make one AS STRONG AS POSSIBLE. Its easier to let a long-term project sit when you have other stuff you can drink NOW. The learning curve on strong wines is soooo much longer too, since there's such a lag before you know whether you made vinegar or something good you want to repeat.
Not saying there only one right way to make wine. Theres not. Ive never made a wine kit or used grape must, yet I've done over 20 different batches. Winemaking just requires patience, and its hard to know if you're doing it right if you cant taste the results. If you're just starting out, do yourself a favor and make it easy and quicker. You will be eager to share it and try some yourself.
Quickest and cheapest way to get started: Make
skeeter pee. following the recipe for amount of sugar to add, and making a starter by dumping a cup of sugar, 1118 yeast and some nutrient into 1/2 gallon plastic jug of some kind of 100% juice (grape or apple would work fine). Shake and put a ballon on top for airlock. Easy peasy.
If you follow the instructions and wait for it to clear, it will be veeery drinkable the day you bottle it, and will be pleeeenty strong enough. Trust me
. You can expect drinkable wine in under 8 weeks if you go this route.
1-2 Gallon batches are the perfect way to do long-term experiments like max strength wine when you start up, Then its only a few bottles you have to store and not look at for a long time, rather than 16-20 bottles that are gonna take up space for years.
