Unlike Europe or the US, India has no annual quota or limits on the quantity of alcohol (wine, beers, ciders, and undistilled beverages) you can home-brew. Instead, the Indian Excise Department has put restrictions on the quantity that can be stocked at any given point of time.
Each state has its limits on what is constituted as commercial quantity. As long as you are brewing/stocking below this threshold and don't reside in a Dry state, you should be safe. I am yet to encounter any law/ government memo limiting the number of batches or number of home-brew parties one can throw, but checking with the local officials is always advisable before you start taking this hobby seriously. Permissible limit to stock as per some state laws are:
Karnataka: 18.5 liters of beer or 9 liters of wine. Tamil Nadu: 12 bottles of beer 650ml or 12 bottles of wine 750ml (It is governed by Tamil Nadu Alcohol (Possession for Personal Consumption) Rules, 1996) Delhi: 18 liters of wine, beer or cider Punjab: 1 case of beer (more with an L-50 permit issued lifetime or annually. Haryana: 12 bottles of beer or wine (more with L-50 permit) Rajasthan: 12 bottles of beer or wine Himachal Pradesh: 48 bottles of beer or wine Goa: 24 bottles of beer
No state in India has legalized home distillery or home alcohol distillation kit. Possession, operating, or dealing with distillation equipment without a license is illegal. However, you can obtain exceptions for medical purposes, herbal extracts, perfumes, and Ayurveda medicines. If you are planning to get a distillation license, then buy a stainless steel distillation kit. Modifying pressure cookers to make crude makeshift stills can land you in trouble.
